Water storage in a private house. Water tanks and autonomous water supply

Storage tank eliminates the problem of lack of water due to interruptions in operation central water supply or power outage if a booster pump was used.

In this article, read about the types of storage tanks and how to choose the right one.

Using a storage tank

A storage tank is a reservoir with a supply of water that acts as a hydraulic accumulator. Its main task is to maintain uninterrupted water supply to the consumer when the central source stops operating.

In the apartment

Each owner of an apartment in multi-storey building faced a water supply shutdown or water supply on an hourly basis. Residents upper floors also familiar with weak pressure due to low blood pressure. The solution to water problems can be storage tank.

The idea of ​​the design is that during a regular water supply, the reservoir is filled, and if the pressure drops or the water supply is turned off, water from the storage is sent to all water intake points in the apartment.

It is recommended to choose the tank size for an apartment in the range of 100-200 liters. This is enough to satisfy the primary needs of an average family of three for a period of several hours to a day. Typically a tank with a float is used, which allows you to maintain an optimal water level.

The volume of the tank is selected individually, based on the area of ​​the apartment, family size, frequency of water interruptions, etc.

In the house

In private houses with centralized water supply, a similar situation arises with water supply. Water consumption in a house is usually higher, because on the territory there is usually a garden, vegetable garden, flower beds, and sometimes also livestock. Thus, the volume of water reserves should be tens of times greater than in the apartment.

For such cases, manufacturers suggest purchasing tanks with a volume of 1500 to 5000 liters (sometimes up to 10,000, but such are rarely used on the farm). The size of the tank will be impressive, but there are usually no problems with placement - a container of water can be installed in the yard, garage, barn and other households. buildings. There is a practice of burying the tank in the ground - this saves usable space Location on.

In the case of a tank buried in the ground, there is another advantage: in winter it does not need to be heated, since the temperature deep in the soil will not drop below zero.

The underground storage tank must have a ribbed surface and be strong enough to withstand the force of soil pressure.

In the country

The dacha differs from the cases described above in that, in most cases, there is no connection to a centralized water supply. Water has to be extracted and stored independently; for this, wells, boreholes and precipitation collection systems are used.

Tank for watering plants

Such a tank is good because the water in it will not be too cold for watering plants, like, for example, straight from a well.

You can use a container for watering plants in your dacha in the event of a power outage (when the pump for a well or borehole is not working).

The watering tank should not be placed in the open sun - if the water heats up excessively, algae and microorganisms will begin to multiply intensively in it.

Tank for shower cabin

Summer showers at dachas are very popular. It helps to freshen up during the day, and in the evening, when the water in the tank has warmed up well, you can take full water procedures.

For a shower, you should buy a tank with a volume of 200-300 liters, preferably flat shape(For convenient installation on the roof of the shower stall).

It’s good if the tank is dark (or better yet, black) in color, this will contribute to more intense heating of the water during the day.

Flat shower tank

How to choose a storage tank

The tank should be selected based on the tasks it will solve in the apartment (on the site). Basic parameters for choosing a container:

• volume;
• material;
• form;
• surface;
• nature of fastening;
• color.

The volume will be individual for each type of need. A tank for an apartment or a private house without a garden can be selected within the range of 100-300 liters. Thus, it will not take up much space and its volume will be enough to meet the primary needs of residents.

The volume of the country tank can be selected up to 5000 liters or more, it all depends on the irrigation area and free space for storing water supplies.

As for the material, you need to be guided by the purpose of the water. If it is to be used for drinking and cooking, the material of the tank must be safe for human health (for example, food-grade plastic). In the case of a summer cottage, plastic also has an advantage over metal, since aggressive components that may be in the water will not actively interact with the container.

The shape of the tank also depends on specific needs. For apartments will do small tank cylindrical(for ease of storage), for country shower– flat (for reliable mounting on the booth). A tank dug into the ground can have any shape.

The surface of the reservoir matters when storing water underground. A ribbed and rough tank will be less subject to soil pressure, which will avoid deformation and movement.

Tank mount too important aspect. The tank can not only stand on the floor (ground), but also be suspended (relevant for small apartments so as not to take up floor space).

Color matters for heating (or vice versa, not heating) the water in the container. If you want the water to heat up under the influence of direct sun rays(shower) – choose dark color, if it is desirable for the water not to heat up above normal (irrigation tank), transparent, white or any light shade will do.

What else you need to know about storing water in a tank

1. The water in the tank should not stagnate, otherwise it will spoil and be unfit for consumption. The water in the tank should be circulated as often as possible.
2. When leaving the dacha for the winter, do not leave the container filled. The water will freeze and the pressure will most likely cause the tank to burst. If supplies were stored in the attic, water will flood the room when it thaws.
3. The container requires periodic cleaning.

Before purchasing a storage tank, calculate how much water your family uses per day. The resulting figure will be the approximate volume of the tank that will suit you.

In modern times, an autonomous water supply system is a fairly common design. This is due to the lack centralized water supply in many country villages built not very long ago. To install such equipment, you will need to purchase a storage tank that can hold a certain volume of water and provide full pressure at any time of the day.

General characteristics of storage tanks

Not all residents of suburban settlements can easily solve the problem of water supply due to the lack of a nearby water source to which a pumping station could be connected. In such cases, the storage tank is indispensable device, performing the functions of a battery.

During the period when water consumption is minimal, the barrel is gradually filled with water in order to supply it water supply network during peak consumption. In order to avoid difficulties during the process of installing it and connecting it to the general system, you should carefully familiarize yourself with the principles of this design.

Device and specifics

Thanks to the storage barrel, the required pressure is maintained in the water supply system. Typically, for such purposes, closed membrane-type equipment is installed, which is made in the form of a container with a rubber membrane located inside. This plate divides the tank into two compartments, one of which is a space consisting of air, the other is filled with water.

The membrane has the ability, on one side, to collect a perfectly clean liquid, and on the other, a composition supersaturated with impurities. This process is called reverse osmosis.

The water supply facility is operated in autonomous networks supplying both hot and cold water. If there is a lack of liquid in the main resource, the storage tank replenishes it from its reserves. The tank is a container made in different options and volumes. It contains pipes for water inlet and outlet, as well as devices for its purification in the form of filters and ventilation system. Higher cost models are equipped with pumping systems.

Control of the liquid level in the barrel occurs through electronic and float devices for determining the level built into the device. From the main source, water is pumped by a pumping station into a storage barrel, fills it to a certain level, and then, when a tap equipped with a float is activated, the water intake procedure is completed.

The liquid chamber is filled after the electric motor of the pump is started, and the dimensions of the air compartment are reduced. The amount of air determines the pressure, which increases as it decreases. Once the collected water reaches a certain level, the pump automatically turns off. It turns on only after the pressure has dropped to a minimum, and at this time liquid is supplied from the water compartment.

The pump operates (turning on and off) automatically, and thanks to the built-in pressure gauge, pressure is monitored. After undergoing purification and aeration, the liquid is supplied to the water supply structure, where it is regulated by means of a water tap. The storage tank performs several functions simultaneously:

• after the pump stops working, it stabilizes the pressure;
• when air or power surges enter the water supply system, it creates protection against hydraulic vibrations;
• maintains a certain volume of water;
• extends the life of the pump.

Due to the water reserve in the storage barrel, there is no shortage of water, and when consumption is low, it is not necessary to activate the pumping system.

Product types

Storage tanks can differ from each other according to the following characteristics:

1. 1. A configuration that can be round, cylindrical or rectangular, or non-standard.
2. 2. Type of construction. Models open type with or without a lid and completely closed.
3. 3. Material used in production. Tanks are made of polypropylene, plastic, of stainless steel or metal.
4. 4. Volume from the inside. Reservoirs can be both small (from twenty to thirty liters) and large (from fifty to ten thousand liters).
5. 5. Purpose. Reservoirs are used for the purpose of cold and hot water supply, irrigation, creating a water supply, and are also included in the designs of summer showers made on their own.
6. 6. Installation option, implying a horizontal and vertical location underground or on the surface.

Models of tanks made of plastic, are considered more in demand due to their practicality. They are distinguished by their simple production, low weight and low price.

Although larger tanks take much longer to fill, they are more economical option, as they allow you to turn on the pump less often.

Stainless steel barrels are resistant to mechanical problems and the occurrence of corrosion, this is due to their considerable cost; often such models are manufactured under individual order.

The method of installing storage tanks having a lower location contributes to the appropriate use usable area. This case implies the presence of a pumping system to supply water to a private house or a bathhouse. With this placement, water is pumped into the storage tank using a pump, simultaneously forming a layer of air.

When the liquid reaches the required level, air forcefully displaces it to the intake points. Often, in order to achieve optimal pressure during the water supply process, a submersible drainage pump, the float of which is installed inside the storage tank.

If a container with a lower location is planned to be used in winter time, then its penetration into the ground should be below its freezing level. In addition, high-quality insulation is also produced. The storage tank of a water supply system used only in summer is usually located at a depth of no more than 50 centimeters from the top layer of soil.

The top arrangement of the tank assumes its installation at the maximum permitted height. This can be on the terrace, attic or under the ceiling, in winter period it is also insulated. The location at the top is capable of providing excellent water intake without the use of a pumping system and provides safe operation reservoir.

Purpose of the tank

In modern times, residents need not only a round-the-clock water supply, but also an ideal pressure that meets the requirements of water distribution equipment. To ensure such water supply, storage tanks are built into the system, which are installed even in the apartment. Such a decision is predetermined by the following cases:

1. 1. On the site of a dacha or private house, there are completely no sources of water supply, and their arrangement is not possible. The storage tank in this situation will be regularly filled from a tanker truck.
2. 2. Despite the presence of a centralized water supply, there are systematic water interruptions or supply is carried out according to one or another schedule.
3. 3. Own water well or another source is not able to meet the needs of residents at any time, which leads to water shortages due to long and continuous withdrawal.
4. 4. For some reason, frequent power outages occur, causing the pumps to stop working.

In each of the listed situations, the water reserve accumulated in the tank will eliminate uncomfortable conditions due to its absence for a certain period (depending on the volume of the tank).

Criteria for correct selection

If there are two or more floors in a private house, the storage tank is installed in the attic, which eliminates the need to install a pumping system. But at the same time, for optimal pressure it will be necessary to place the equipment at a certain height, followed by the installation of a device for heating the water to avoid freezing in winter.

When choosing a storage tank, you need to carefully study all its characteristics. The capacity of the container should be optimal for the number of people for whom it is intended to consume water. It is very important to take into account the number of areas in the room that collect water, for example Appliances, taps and shower. In addition, it is worth considering the possibility of simultaneous water consumption by several consumers.

When choosing a storage tank, you should perform a performance analysis autonomous resource or the order of operation of a centralized system. If the supply of electricity or water stops for two or three hours, then a barrel with a volume of one hundred liters will be able to compensate for these inconveniences. In case of frequent shutdowns utilities you will need a container with a much larger displacement.

It makes no sense to purchase and install a tank with a volume of five cubic meters if within a day the well can fill it with no more than five hundred liters.

When considering the material for manufacture, you need to remember that tanks made of metal or stainless steel are mainly intended to create a reserve hot water. And since they are highly expensive, it makes no sense to purchase them for storing cold liquid. For this purpose, polypropylene barrels with markings for food products. Particular attention must be paid to the quality of the product, since plastic that has a smell may only be suitable for storage process water.

Top Mounting

Installing a tank in the attic is considered the most common solution in the process of arranging an autonomous water supply structure in a private house, country house or bathhouse. For this purpose, it is necessary to purchase a container having the required volume and shape, the installation of which will be carried out on beam floor, located at the top. If this place is inconvenient for residents, then the storage tank can be located in any suitable part of the attic.

The installation event includes several stages:

1. 1. The base on which the tank will be located is strengthened; boards with the required width are laid on top of the floor beams.
2. 2. A storage container is installed on the prepared base.
3. 3. The float valve is installed, an indent of 7.5 cm is made from the top edge, and a hole with the required diameter is cut out at the marked location. Then a part of the valve from the tail side, equipped with a plastic washer for sealing, is passed through it. Meanwhile, a rigid plate and the same sealing washer are mounted on the opposite side of the tank, and then a nut is screwed on. All fasteners must be properly fixed and a connector must be attached to the tail section, which acts as an intermediary between the tank and the water pipe.
4. 4. To install the outlet pipes, holes of the appropriate size are made. A connector with a washer is screwed into the holes located on the inside of the tank. In order to secure the thread, you should use a special tape, and then put on the washer and tighten the nut.
5. 5. Shut-off valves are placed in the outlet pipes.
6. 6. An overflow is carried out, for which a mark is fixed, located two and a half centimeters below the float valve, after which a hole is made.
7. 7. In case of overflow, the pipe is led into the sewerage system and attached to the walls of the container using connectors in a similar pattern. After this, pipes with compression clamps are supplied. The prepared parts of the piping system are attached to the walls of the tank and to the wooden base.
8. 8. The attached storage tank is filled with liquid to check the system for leaks and adjust the float-type valve.
9. 9. The tank is insulated using polystyrene or mineral wool.

Installing a tank in the ground

Before proceeding with the installation of the tank, using the option with a lower location, you should select the most suitable location for this. In this case, it is recommended to purchase structures with a round configuration; in addition, it is worth focusing on the stiffening ribs necessary to improve the mechanical characteristics and ideal installation of the device.

When installing a storage tank that has a different shape and without ribs, then for correct installation a concrete shell will be required. With its help, you can properly fix the device in the ground.

The part of the structure located on top must be equipped with a special hole made in the form of a hatch. This will allow you to periodically monitor the condition of the equipment from the inside. The inclination of the storage tank should not exceed fifteen degrees, which will make it possible to clean it without any effort. special effort.

At the end of the work, an expansion tank (hydraulic accumulator) is connected, designed to compensate for the pressure inside the system.

Installing a storage tank is not a complicated procedure and provides an opportunity throughout the year not to depend on the water supply schedule of a centralized water supply system.

Every owner of a private home sooner or later thinks about installing an autonomous water supply system. The fact is that the majority country cottages for many years it has not been done centralized system water supply. As a result, home owners have only two options: install a storage tank or continue to carry water in a bucket.

Of course, the romance of country life has its merits. But the lack of water in the house does not apply to them. This is a huge drawback that spoils all the pleasure of staying in a private home. The installation of a water supply system with a storage tank changes the situation radically.

You braid the house with pipes and get hot water wherever you need it. True, for this to become a reality, it is necessary to install a boiler in the water supply system of a private house with a storage tank.

Purpose of the storage tank

This device cannot be called too complicated. Nevertheless, it is indispensable in the water supply system of a private home. As the name suggests, the storage tank is used to store water. Imagine a situation where you still have water supplied to your dacha, to your private home. But the supply in such towns is always unstable. This is where the reservoir comes into play.

Important ! The storage tank can hold a large amount of water and maintain a stable pressure 24 hours a day.

The very principle of operation of a storage tank in the water supply system of a private house is interesting. You don't have to turn anything on or worry about running out of water in the kitchen because the device will take it all up. The tank was very cleverly designed. It stores water little by little, creating a reserve supply for critical situations.

What are the types of water supply systems for private houses with storage tanks?

Tank at the top

In this water supply scheme for a private house, the storage tank is mounted on the second or third floor. You can also install the tank in the attic. The operating principle is the same as that of a water tower.

When installing a storage tank at the top of the water supply system of a private house, water will flow through the pipes by gravity. This, in turn, will save you a lot of energy and allow you to save on long utility bills.

Important ! This tank is extremely easy to maintain.

Separately, we need to talk about the force of pressure. Despite the fact that the water flows by gravity, the pressure cannot be called particularly strong. More precisely, it directly depends on the height at which the tank is located.

For example, if the container is located at a height of about 10 meters, the pressure will be 1 atm. To simplify the calculations, let’s take a three-story house. Let the height of each floor be three meters. When installing a tank on the roof of the third floor, the pressure on the first floor will be exactly one atmosphere.

The main disadvantage of this system is that with each floor the pressure will be lower and lower. And below. As a result, on the second floor it will be about 0.6 atm, and on the third floor even less. Although if you are going to install taps only on the first one, this is more than enough.

Important ! The tank takes up useful space.

Very often, the attic at the dacha is used to store things dear to the heart that one simply does not dare throw away. Besides modern technologies allow you to make an excellent room from the attic floor with all the amenities. True, this will require insulation and waterproofing, but the result is worth it.

Advice ! If you have plans for the attic, then don't give up on them for an overhead tank. Just take it outside the house to the overpass.

Location below

If you want to make the most of all the space available inside a private home, you will need just such a water supply system. Moreover, even from the outside the container will not take up even an inch of land.

Tell me, is this impossible? It's actually quite simple. The reservoir is buried in the ground and from here the water supply to a private home is realized. The container does not need to be buried deep. Half a meter will be enough.

You can safely grow flowers on top of the tank. A private home's water supply system dug into the ground will not harm them in any way. The capacity of the container is not limited by anything. But you must remember that large volume It takes longer to collect, and accordingly, water intake on especially hot summer days can become critical.

Important ! When choosing a container, you need to take into account the thickness of the water layer and its capabilities, as well as the needs of your subsidiary household.

Unfortunately, the lower location of the water supply system of a private house has its disadvantages. The most significant is the need to purchase pumping station, and this means additional energy costs in the future.

Underground tanks in water supply systems of private houses are made from special materials, which are able to withstand increased moisture and even freezing. However, breakdowns sometimes happen, and then it is extremely difficult to restore the system. After all, the reservoir is buried underground.

Important ! In order for the water tank to serve you for a long time, the soil must be insulated. This will prevent frost from affecting the structure.

Place the tank in the ground

Installing a tank for water supply in a private home begins with choosing a suitable location for installing the product. It is desirable that the design of the container has a round shape. Please pay Special attention on the stiffening ribs, without them it will not be possible to install the device properly.

If you buy a storage tank of any other shape and without ribs. About him correct installation you will have to take extra care. For this you will need a concrete shell. This will ensure reliable fixation in the ground.

There should be a special hole at the top of the structure. It is best done in the form of a hatch. It is necessary in order to carry out an audit from time to time, looking at the condition of the storage tank of the water supply system of a private house from the inside.

Important ! The storage tank must be installed with an inclination of no more than 15 degrees. This will make cleaning much easier, since sediment will accumulate just under the hatch.

Installing and connecting the storage tank

A float valve must be installed on the inlet pipe of the storage tank for a private house. You also need to think about an overflow pipe in case the float valve breaks. It will insure the system against liquid overflow.

Important ! Provided that the water is taken from your own source, via a pump, take care of the float switch.

A filter must be installed at the entrance to the storage tank for a private building. They come in three types:

• centrifugal,
• cyclone,
• mesh.

Perhaps, the best option for a storage tank of a private house is exactly strainer. Its price is relatively low, and its efficiency is more than enough to purify not particularly contaminated water. The remaining two types are needed when the liquid has high level pollution.

It is best to fill the tank through a diffuser. This precaution will prevent sediment from rising and entering the water supply. A pipe cuts into the storage structure from above. It will act as ventilation.

Important ! The pipe opening should be directed downwards, and a special mesh should be secured to prevent debris from entering the system.

The main role when connecting the water supply system of a private house with a storage tank is played by the pump. They are the ones responsible for delivering water to the end consumer.

Important ! The suction line must have a check valve. It is installed on the pipeline leading to the house.

Of course, when connecting you cannot do without such important elements water supply systems for a private house with a storage tank, such as:

• water level sensor,
• float switch,
• protection relay.

All these elements in the water supply system of a private home must be ideally combined with each other, and then everything will work perfectly.

The pump is connected to the pipeline via a reinforced hose. More often outside diameter pipe is 32 mm, but exceptions are possible. The pipeline goes to the storage tank.

In some cases, in private houses, storage tanks are installed between the floors. In such cases, you need a flooring made of strong boards. This will distribute the load as evenly as possible.

Connecting the expansion tank

The expansion tank is slightly different from the storage tank. It is also called a hydraulic accumulator. The role of this device is to compensate for the pressure inside the system.

Important ! A volume change membrane is installed in the tank itself, which ensures normal work water supply A similar device is installed in heating systems.

If the expansion tank for the water supply system of a private house is open, it is installed at the very top. Closed type structures must be installed in front of the circulation pump. This is the most suitable place.

When connected, the coolant is supplied from above. Also, the system must have a pressure gauge and safety valve. Without this, the heat and water supply in a private house will not be able to function normally.

Results

It is difficult to overestimate the importance of storage tanks for water supply systems of private houses. They allow you not to depend on the stability of the water supply all year round. In addition, due to the simplicity of the design, they are easy to install.

Expansion tanks for private houses additionally perform the functions of protection against water hammer and are most often used in heating systems. The best solution for a private home is a membrane type of device.

A water supply system that operates autonomously will not surprise anyone today. Similar designs practical and very convenient, but their operation very often requires devices that people operating centralized water supply, they simply don’t know.

Need for use

For example, a water supply will be able to operate uninterruptedly for a long time only if it contains an expansion tank. On the market of modern goods you can find many various models similar devices. In order to pick up best option, you need to navigate the types of equipment and imagine the principle of its operation.

Equipment design

The storage tank for water supply is designed to maintain a certain pressure in the water supply system. Most often, a closed membrane tank is used for this. It is made in the form of a container, inside of which there is a rubber membrane. It divides the described device into two compartments: one of them is air, the other is water. After starting the system, the electric pump fills the water chamber with water. The volume of the air compartment decreases. The smaller the volume of air in the container, the higher the pressure will be. As soon as it exceeds a certain mark, the pump will automatically turn off. It will be activated only after the pressure drops below the minimum mark, and water begins to flow from the water compartment. The on/off cycle will repeat automatically. The user can check the pressure in the system using a pressure gauge that is installed on the equipment. You can configure the device yourself by choosing the most suitable operating pressure range.

Expansion tank functions

The storage tank for water supply is designed to perform several functions at once, namely: to maintain pressure when the pump is turned off; protect the system from water hammer, which can be caused by air entering the pipeline or voltage drops in the network. Among other things, this element of the water supply system is capable of storing a certain amount of water. This component is also necessary to protect the pump from premature wear. Using a tank allows you, when water consumption is low, not to use the pump, but to satisfy the need for liquid due to the volume that is stored in reserve.

Tank selection

If you decide to install a storage tank for water supply, then it will be important to first understand what type of membrane equipment is suitable for you. You can choose a device that has a replaceable membrane. A distinctive feature here is the ability to replace the membrane. It can be removed through a special flange that is held in place by bolts. One more point must be taken into account: if we are talking about a device of impressive volume, then to stabilize the membrane, it is additionally fixed with its back to the nipple. Another one distinctive feature This device is that the water filling the tank will remain inside the membrane without contacting the inner surface of the product. It protects metal surfaces from corrosive processes, and water from pollution, extending the life of the equipment. If you are choosing a storage tank for water supply, then you can purchase a model with a replaceable membrane in both vertical and horizontal versions.

When should you choose a tank with a stationary diaphragm for installation?

In these devices, the inside of the container is divided into two compartments by a membrane. It cannot be replaced, and therefore, if it fails, the equipment will have to be completely replaced. One compartment contains air, and the other contains water, which comes into contact with the inner surface of the metal device, which can cause rapid corrosion. In order to prevent destruction of the metal and contamination of the liquid, the inner surface is coated with a special paint. But such protection is not always durable. You can choose such devices in vertical or horizontal design.

Features of the right choice

If you decide to install a storage tank for water supply, you should pay attention to its main characteristics. It is on their basis that equipment should be purchased. When selecting the volume, it is important to consider how many people will use the water supply system. It is also important to calculate the number of water intake points: this should include taps and showers, as well as Appliances according to the type of dishwasher and washing machine. Please note that there is a possibility that water will be consumed by several consumers at once. In the store, you should also pay attention to the maximum number of stop and start cycles in one hour for pumping equipment.

Preparation before installation

When choosing a storage tank for water supply, you should purchase one whose volume is from 20 to 24 liters. This is true when the number of consumers is no more than 3 people, and the pumping equipment has a capacity of 2 cubic meters per hour. You should prefer a tank volume of 50 liters if the number of consumers increases to 8 people, and the pump capacity is 3.5 cubic meters per hour. The maximum volume, which is 100 liters, is suitable for a number of consumers of more than 10 people and a pump capacity within 5 cubic meters at one o'clock. Before choosing a specific tank model before starting installation, you need to take into account that a smaller tank volume will contribute to more frequent pump shutdowns. Among other things, a smaller volume will indicate a greater likelihood of pressure surges in the water supply system. Due to the fact that the equipment acts as a reservoir for storing water reserves, it is possible to adjust the volume of the expansion tank even before purchasing the equipment. The design of the device allows the installation of an additional tank. This can be done during the operation of the main equipment, without labor-intensive dismantling. After completing the installation of the new device, the volume of the tank will be determined by adding the volumes of the tanks installed in the system.

If you decide to make a water supply device with a storage tank, then it is important to consider that you should not chase low cost by choosing a tank from a little-known manufacturer. The pursuit of cheapness can lead to more significant expenses. Most often, cheap materials are used to produce attractively priced models, and, as practice shows, they are not of high quality in all cases. It is especially important to pay attention to the quality of the rubber that underlies the membrane. The service life of the tank, as well as the safety of the water, will depend on this.

When buying a storage tank, you must check the price of the consumable element, which is true for models with a replaceable membrane. Most often, in pursuit of profit, unscrupulous manufacturers inflate the cost of a replacement membrane. In this case, experts advise choosing a model from another supplier company. Large companies are responsible for the quality of their products, as they value their reputation.

Features of installation

A water supply system with a storage tank involves installing a container in a room where the temperature does not drop below 0 degrees. TO air valve it is necessary to provide comprehensive access, this will allow the pressure in the air chamber to be adjusted. During installation, there should be no obstacles in accessing the shut-off valves, nameplate or drain tap. Under no circumstances should the membrane tank be subjected to static load; it should be protected from pressure from pipes or other units. Installing a pressure reducer, which should be located after the water meter, will ensure a certain pressure in the expansion tank. When the safety valve is activated, the pressure level must not exceed the maximum permissible value. Installation of expansion membrane tank assumes that the safety valve is installed in front of the flow fittings; it must be positioned along the flow direction. When considering the installation diagram of the expansion tank, you need to take into account that installation should be carried out from the supply side cold water to the heating device. Experts exclude the possibility of installation at the exit.

How to avoid mistakes during the connection process

If you have a storage tank for water supply (200 liters or less - not so important), then, of course, it is quite possible to install it yourself. However, you only need to prepare quality tool, as for gas and adjustable wrenches. These components will be key figures in carrying out installation work. In addition, you may need a key for installation metal-plastic pipes, as well as a stepped wrench designed for Do not use materials as a sealant that are not used for carrying out similar works. For example, some inexperienced DIYers use cheap sealant to plastic windows, but it is designed for a different temperature. Initially, such connections may look very attractive, but when the system is started, the sealant will not withstand exposure to high temperatures. In any case, after this you will have to fix the leak that has arisen. If you are installing a water supply for a private home, the storage tank should be installed in such a way that access to it is not difficult. You should not choose the volume of the storage tank by eye. The installation must be carried out in accordance with the norms and regulations for operational safety.

What else is important to consider when installing yourself?

If you independently install a storage tank for water supply to your dacha, you must provide for the possibility of dismantling the connecting pipeline, which may be necessary for repairs and replacement of equipment. The diameter of the connected water supply elements should not be smaller than the diameter of the pipe. Be sure to ground the device, this is the only way to prevent electrical corrosion. If you are installing a water supply at home with a storage tank, then the device should be installed on the suction side of the pumping equipment. In this section, which is located between the pump and the connection point, it is necessary to exclude all elements that could introduce hydraulic resistance into the system. The make-up line must be connected to the system circulation circuit.

Conclusion

A storage tank for water supply is an integral element of an autonomous system. It is able to maintain the required pressure, preventing premature wear of pumping equipment. Among other things, it can help you save some water.

The main stage of arrangement country house or a private bathhouse is to install a modern autonomous water supply system.

To implement this, a reliable storage tank for water is used.

No less important is the question correct placement devices so that the finished water supply system functions properly throughout its entire service life.

Design and principle of operation

A storage tank for water supply is provided to create the necessary reserve of water for drinking and technical needs.

This device is used in modern autonomous hot and cold water supply systems. When a deficiency occurs water source, the drive replenishes it from available reserves.

Also, water tanks are successfully used for household needs for arranging summer showers and garden irrigation systems.

Note! Storage at home is designed to store a sufficient supply of water resources and maintain powerful pressure throughout the day.

Water tanks are represented by hollow containers of various configurations and volumes, which are equipped with inlet and outlet pipes, cleaning filter meshes, ventilation holes and technical revisions. More complex models are equipped with additional pumping stations.

The water level is controlled using built-in shut-off valves - float or electronic. Pumping station or submersible pump(over simple models) supply water from a ready source to the storage tank.

The tank is filled to the required level, after which the regulator (float valve) is activated and the intake is completed.

When the water is drained, the pump automatically turns on and the liquid supply process begins again.

Water storage tanks can be divided into several categories:

1. According to the design - round, cylinders, rectangular, non-standard;
2. By design - open (with or without a neck, protected by a lid) and closed (completely sealed);
3. According to the material of manufacture - plastic, metal, polypropylene;
4. In terms of internal volume - from 20 to 30 liters (small), from 50 to 10 thousand liters (large);
5. By purpose - for water supply (cold, hot), summer shower, irrigation systems, water supply;
6. According to the installation method - vertical and horizontal placement, inside and underground.

Plastic

The most popular and practical models are plastic tanks, which are characterized by ease of production, light weight and low cost.

Large tanks take longer to fill with water than smaller tanks, but are also more economical. After all, the larger the volume, the less frequently the pump is turned on.

Metal

Metal tanks are made of stainless steel, resistant to corrosion and mechanical damage. This determines high cost similar tanks, so they are often made to order.

To reduce negative impact corrosion, metal hot water containers are coated inside with a reliable heat-resistant enamel layer.

The most affordable option is plastic or polypropylene storage tanks with the appropriate level of thermal conductivity.

Location of water tanks

The location of the tank determines the type of plumbing and equipment required for reliable and uninterrupted operation of the off-grid system.

A modern storage tank for water supply to a home and bathhouse has two installation options - upper and lower positions.

Upper

Such a scheme involves installing a storage tank at the maximum permissible height– terrace, second floor, attic, on the roof or under the ceiling. The height of the location is proportional to the pressure force - for every 10 meters 1 bar of pressure is added.

When operating the hydraulic accumulator in winter, the device is additionally insulated.

The top position provides best fence water even without the use of a pumping station, as well as simple and safe operation of the container.

Lower

This method of installing a storage tank provides for the rational use of free space. In this case, a pump or pumping station is required to supply water to the house or bathhouse.

When placed at the bottom, water is pumped into the storage tank using a pump, resulting in the formation of a special air gap. When a certain level of water in the tank is reached, the air with maximum force pushes it to the intake points.

Often, to achieve optimal pressure when supplying water, a submersible drainage pump with a float installed inside the tank is used.

If a bottom-mounted water tank is planned to be used in winter, then it must be buried in the soil to a depth below its freezing level.

Additionally, it is provided reliable insulation. When installing a summer water supply system, the storage tank can be located to a depth of up to 45 cm from top level soil.

Important! For underground installation, the tank should be installed with a slight slope of up to 16 degrees. This will ensure one-sided accumulation of sediment under the cover.

Installation process

Most affordable option organizing an autonomous water supply system in a house or bathhouse - installing a container in the attic.

To do this, you need to make or purchase a bath tank of the required volume and configuration.

The container is mounted on the top beam ceiling or in any convenient location attic.

Installation work is carried out in stages:

1. The base under the water tank is being strengthened. The floor beams are covered with wide boards.
2. The drive is installed on the prepared base.
3. A float type valve is being installed. Step back 7.5 cm from the top edge, make a mark and cut out a hole of the required diameter. The tail part of the valve with a plastic sealing washer is threaded into the hole. A special stiffening plate is installed on the opposite wall of the container, another sealing washer is installed, and a nut is screwed on. All fasteners are securely fixed, a connector is screwed to the tail part, with which the water pipe is connected.
4. Holes are made for outlet pipes of the required size. Into the finished holes with inside container, a connector with a washer is screwed in. The thread is strengthened with a special tape. Next, put on the washer and tighten the nut.
5. Shut-off valves are inserted into the outlet pipes.
6. Overflow is in progress. To do this, set a mark 2.5 cm below the location of the float-type valve and make a hole. The overflow pipe is led into the sewer system and secured to the walls of the tank using connectors using a similar principle. Next, the pipes are connected with compression fixation. Finished plots pipeline system are mounted to the walls of the tank and a wooden base.
7. The connected tank is filled with water to check the tightness of the system, as well as to regulate the float valve.
8. The container is insulated using polystyrene sheets or rolled mineral wool.

In this simple and reliable way you can arrange autonomous system water supply, the main element of which is a storage tank for a bathhouse or home.
