Often, in the process of replacing a pipeline, you have to deal with the fact that the diameter of one end of the line is 110 mm, and the cross-section of the other is larger or smaller. And how to replace a sewer riser? A compensator will come in handy - an excellent transition device, specifically designed for connecting elements with a difference in cross-section.
By definition, a compensator is a device for compensating linear extensions of a pipe system. Each material has individual linear expansion indicators, so an expansion joint is not needed for every pipe line. The relevance of the element increases if there is a sewer system hidden in the screed or wall. By appearance The element is a corrugated pipe equipped with connecting flanges on both sides.
Important! The use of flanges is shown for pipes with a cross-section of 63-110 mm; for pipes with a diameter of up to 63 mm, a threaded compensator is available, as well as an element equipped with a rubber corrugated seal and a union nut.
A plastic sewer compensator is indicated for repairing/replacing a riser PVC pipes without dismantling the entire system. Representing a piece of a curved shape, the compensator has the same cross-section as the elements of the main line and is inserted by cutting out the piece and fusing the compensator with a blowtorch.
Advice! Compensators are mounted only on sewer structures or water pipes for hot water.
Often the installation of an element is required to renovate a bathroom or toilet room, when differences in floor level require raising or lowering the cross on the riser to arrange the angle of drainage into the sewer.
Polypropylene elements have almost universally replaced old metal ones sewer risers. Thanks to its undoubted advantages, plastic is becoming more and more in demand. However, in order to get a truly high-quality insertion result and install the compensator correctly, you need to take into account some simple factors:
Important! It is very reasonable to provide thick pipe walls with increased strength, for which a welded installation method is used. Welding is also indispensable if the sewerage pipeline is intended to be used in conditions of increased temperature exposure.
Scheme of operation of inserting into a plastic riser:
And advice: to connect a pipeline whose elements are made of them different materials a system of fittings equipped with a polymer coupling and pipe thread. Now you don’t have to guess why the pipe is needed and what to do with the PVC pipeline if it is leaky - the compensator will allow you to quickly and without much labor and time to repair the breakdown without disassembling the entire system.

Vacuum valves
A vacuum valve or sewer aerator is used in internal sewage systems 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, a vacuum valve is used for local aeration of sinks, bidets, toilets, where a large flow of 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.

Main characteristics of the pipes:
Products comply with domestic GOST and international technical standards. Products can be delivered to any region of Russia.
Expansion pipes made of PP polypropylene are necessary to compensate for construction tolerances and simplify installation and assembly work. Recommended for use at the bottom of risers in technical rooms. The presence of a branch pipe allows you to avoid deformation and destruction of pipelines, and makes it possible to remove damaged network elements without disassembling it.
Thanks to the bell-shaped design, the pipes are easy to install. They are equipped with a rubber sealing ring, which ensures high tightness and reliability of the connection. Additional qualities: resistance to corrosion, aggressive environments. Can function normally at both high and low temperatures.
Often during installation or renovation of interior 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 sewer compensator 110 mm. 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.
For the production of sewerage pipes, manufacturers traditionally use:
Just a few years ago, plumbers preferred to work with metal pipes. However, this material has several disadvantages:
Therefore, with the start of production polymer pipes builders increasingly prefer them. There are three types of plastic products, including sewer 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.
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 to horizontal sections when unifying drainage 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.
Polypropylene expansion joints for sewer pipes are used most often. Their popularity is explained by a number of advantages.
Features of polypropylene adapters:
Important! Manufacturers produce a wide range of expansion pipes with different sections and shape. This makes it possible to install sewer networks of any design and complexity.
Technical characteristics of polypropylene products:
To ensure that the insertion of the compensator is correct and of high quality, you should:
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:
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:
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.
