Vacuum valves
A vacuum valve or sewer aerator is used in systems internal sewerage to prevent entry into the room unpleasant odors, harmful gases and vapors from the system, as well as to relieve pressure in the system. Vacuum valve 110 (aerator 110) is installed on top of vertical risers in the sewerage system in attic spaces, toilets, bathrooms, etc., where uninterrupted flow to the valve will be ensured fresh air.
Also vacuum valve used for local aeration of sinks, bidets, toilets, where high consumption waste liquid can lead to the creation of air vacuum (suction of water from the siphon water seal), in this case, as a rule, a vacuum valve 50 is used.

PP compensation pipe DN 110 mm sewer PVC inner single-socket sliding PP D 110 mm for internal sewerage
Fasonant part for connecting sewer pipes PVC pipes and shaped parts without socket joints. The thrust flange in the coupling design provides correct installation pipes and fittings. PVC fittings provide a tight, hermetically sealed connection of sewer pipes. The bells are of high quality rubber seal resistant to aggressive environments.
Compensation pipe for internal sewerage- gray polypropylene sewer fitting. It is intended for repairing the intra-house sewerage network in both residential and non-residential buildings and premises.
Sewer compensation pipe It has long term service (at least fifty years). The standard diameters of this fitting coincide with the standard diameters of gray sewer pipes and are 5 and 11 centimeters.
Compensation pipe 110 mm used as a connecting fitting when installing non-pressure water pipelines of the appropriate diameter. Its task is to compensate for construction tolerances and deformation loads that can destroy PP pipes. Since standard construction allows a difference of several centimeters, the expansion pipe DN 110 can significantly simplify installation work.
Functions of the polypropylene expansion pipe:
simple repair of damaged sections of polypropylene pipes;
compensation of construction tolerances and axial displacements;
compensation thermal expansion and deformations.
Which expansion pipes should you prefer?
In Moscow, the greatest demand is for inexpensive plastic pipes from the RosTurPlast company from Russia, as well as products German manufacturer Ostendorf, the price of which is more justified high quality. You can buy original fittings from these brands in the Santekhkomplekt online store. Besides ordinary products different lengths, noise-reducing and flexible pipes are available for sale.

Often, during the process of laying or repairing the internal sewer network, a problematic situation arises. It consists in the fact that the pipeline linearly expands and contracts with temperature changes. What to do in this case? Then you can use a 110 mm sewer compensator. This material will tell you what it is.
Essentially, the compensator is a fitting. Namely, an element that serves to level out linear extensions of the sewer network during its operation.
Manufacturing materials
For the production of sewerage pipes, manufacturers traditionally use:
- metal: steel and cast iron;
- molded reinforced concrete;
- asbestos cement;
- ceramics.
Just a few years ago, plumbers preferred to work with metal pipes. However, this material has several disadvantages:
- he is very heavy;
- installation metal pipeline complex and time-consuming;
- Steel sewers rust, and cast iron sewers quickly become overgrown with sediment.
Therefore, with the beginning of the production of polymer pipes, builders are increasingly giving preference to them. There are three types of plastic products, including sewer expansion joints:
- polypropylene products;
- polyethylene analogues;
- polyvinyl chloride expansion joints.
Important! The most popular are polypropylene products. They make it possible to solve pressing engineering problems related to the installation and use of sewer networks.
Scope of application, cross-section and design features
All materials used for sewerage installations have their own linear deformation parameters. Therefore, the plastic expansion joint is not suitable for all pipelines. The effectiveness and demand for this fitting increases if the drainage network is walled up in floors or walls.
The compensator is mounted on a sewer pipe at the bottom of the risers, located in technical, utility, basements. It gives the desired slope horizontal sections when unifying waste branches made of different materials.
The fitting allows you to compensate for deformations and failure of the network due to its linear temperature contraction/expansion.
Compensators are often used to repair internal sewer systems. They make it possible to replace failed sections of the pipeline without completely dismantling it.
Often, installing a fitting is necessary when renovating a bathroom or restroom. In this case, it is used if height differences in the floor require raising or lowering the riser cross to create optimal angle dumping sewage into it.
The expansion pipe made of polyethylene and polypropylene is a straight section of pipe. On one side it is equipped with a 110 mm connecting socket. It contains an o-ring seal made of rubber.
Polyvinyl chloride products can be corrugated, which improves their compensation characteristics. There are also products with a curved configuration; they are designed for installation or repair of rotating sections of sewer networks.
Advantages and technical characteristics of plastic expansion joints
Polypropylene expansion joints for sewer pipes are used most often. Their popularity is explained by a number of advantages.
Advantages of polypropylene pipes
Features of polypropylene adapters:
- long service life: the average service life of products is 30–40 years;
- low weight: due to this, labor costs when installing the compensator are low;
- easy installation, similar to constructor assembly;
- resistance to aggressive chemicals and temperature changes;
- the material is not subject to corrosion;
- due to the smoothness of the inner walls, deposits grow on them very slowly;
- the material is environmentally friendly, which is confirmed by hygiene certificates;
- Such compensators are inexpensive.
Important! Manufacturers produce a wide range expansion pipes having different sections and shape. This makes it possible to install sewer networks of any design and complexity.
Technical characteristics of polypropylene products:
- total length - 28 cm;
- outer diameter of the bell - 11.5 cm;
- internal section of the bell - 11 cm;
- wall thickness - 3.2 mm;
- continuous operating temperature limit - +95 degrees;
- pressure in the network in which the compensator is operated is without pressure;
- color - pale gray;
- transported medium - sewage;
- warranty period - 24 months;
- The declared service life is 50 years.
How to install an expansion pipe?
To ensure that the insertion of the compensator is correct and of high quality, you should:
- take into account the thickness of the pipe walls;
- determine the length of the sewer network in order to calculate the level of pressure on the connected joints.
Important! The best option increase the tightness of pipe connections with thick walls - use silicone sealant. This material is elastic and therefore will not interfere with compensatory movements. Sealing network elements is also effective when the sewer system is planned to be used with increased exposure to extreme temperatures.
Algorithm for inserting polyethylene and polypropylene expansion joints into the riser:
- first, a section of the pipeline to which the compensator will be connected is cut out with a metal hacksaw;
- the edges of the cut are processed with a file or coarse emery cloth to remove burrs;
- then silicone sealant is applied to the upper end of the riser (it is better if it is a special plumbing compound);
- after that, the compensation bend is pulled onto the treated side until it stops;
- then covered with sealant down side riser;
- then the corresponding end of the compensator is fixed in its socket;
- then the riser is fixed;
- After the silicone has dried, the system can be used.
A 110 mm compensator for sewerage made of polyvinyl chloride can be mounted using the same method as polyethylene and polypropylene analogues, that is, by pairing elements in a socket.
Installing PVC adapters is quite easy and does not require special preparation. Some tips for installing these fittings:
- It is best to cut pipes with a hacksaw with small teeth, for example, a metal saw, so there will be fewer burrs on the cuts;
- Dry and clean sides of the elements must be sanded and sealed;
- All cavities that appear must be filled.
The compensator makes it possible to repair the sewer system without dismantling large sections of it. His plastic varieties Installed simply and quickly. You do not need to be a qualified plumber for this type of work.
