During the period of mass development, most of the house communications were made of cast iron or steel. The constructions were not only heavy, bulky, but their service life was long over. They were mounted by welding, and the outlets were sealed using tow or cement. It was in these places that accidents most often occurred.
The development of technology laid the foundation for the use in pipes and fittings of new materials - PVC, polyethylene, polypropylene. The plumbing tee, which is also made from polymers, and successfully connects even with cast-iron risers, has become especially popular.
If earlier such a repair was only possible for the ZhEK specialists who brought in a new pipe, welded instead of the old one, and screwed up such a connection in the old fashioned way, now sewer repair work can be done independently, in a lightweight version and without any welding.
What material to prefer?
Repair in the bathroom is often associated with the replacement of plumbing, which automatically causes a desire to update the pipes. Polymer pipes have many advantages over iron pipes, which ensured their high popularity. Plastic pipes and PVC sanitary tee have a smooth inner surface, which is not susceptible to limescale coating, the accumulation of various deposits in which microorganisms can develop.
It is much lighter in weight, cheaper, has a longer service life and a lot of universal components, which makes working with them convenient and simple.
Connecting elements in the sewerage system
In addition to pipes and adapters, one of the main elements of the pipeline is a plumbing tee, which is necessary for creating bends, bends or connecting additional plumbing devices.
Tees are different in shape, vary in size and function. They are used both in internal structures and in the installation of external pipelines. For example, a plumbing plastic tee is used to drain sewage and is designed for temperature conditions up to +90. It has resistance to alkalis and acids (although in small quantities).
By the way, you need to know that plastic for outdoor use has a brown (orange) color, and for indoor use - gray. You can choose tees for connecting pipes of different diameters and for different purposes.
How to install a plumbing tee yourself?
Connecting parts of a plastic pipe is very easy. If the tee has a rubber seal, then the pipe is inserted tightly, just moisten the rubber with soapy water. If not, the outside of the pipe and the inside of the tee are greased with glue or sealant and connected.
If the pipe is longer than necessary, it is shortened, part of the pipe can be cut with a hacksaw with small teeth, and then a small chamfer to make a small chamfer with emery paper or a file to facilitate joining.
The sanitary inspection PVC tee has a special purpose - it has a plug on the lateral branch, which is removed when eliminating blockages.
