Features of installation of pipelines from polypropylene and polyethylene.
At present, industrial enterprises produce such types of plastic pipes:
- from polypropylene( PP) and polyethylene( PE);
- from polyvinyl chloride( PVC);
- plastic pipes.
Each of the listed options have their advantages and disadvantages, as well as their own features of the installation and wall mounting technology, which we will consider below. 
PP and PE pipes are designed for hot and cold water supply, as well as for drinking or technical water in central and local heating systems.
Before starting the installation of such pipes, it is necessary to prepare the material and tools, and also to lay the route.
Fastening of such pipes to the wall or ceiling are special plastic fastening clips and dowel - nails of the appropriate size. In order to get bends, use fittings or heat the tube to 140 degrees with a construction hair dryer.
Another way to connect polypropylene pipelines is cold welding, the process of which is as follows:
- pipe is cut and calibrated;
- the joint site is degreased with a solvent and smeared with glue the outer surface of the pipe and the inside of the coupling;
- pipe is quickly inserted into the coupling, turns a little and fixes for 15 seconds.
For the fastening of such pipelines, first of all, a small hole is made in the wall, which is suitable in size to the plugs. Then in the hole, what happened, put the clip. You can hammer the dowel with a hammer or a Phillips screwdriver.
At the end of the PP operation, the pipe is inserted into the clip fixed to the wall.
Features of installation of pipelines from polyvinylchloride.
PVC pipes are assembled very simply, without the use of special tools and attachments. It is enough to determine the bell on the end of the pipe and insert a narrower part into it. In general, the technology of assembling a PVC pipe is as follows: 
- the expanded part of the pipe is washed with soapy water and insert the O-ring into the slot provided for this;
- the smooth end of the second pipe is also moistened with the same soap solution and connect it to the socket of the first pipe;
- pipe connections with fitting are carried out on the same principle.
Attachment to the wall of the already assembled structure is carried out on clips or clamps, which are installed with the help of dowels or self-tapping screws.
Installation of metal-plastic pipeline.
For the assembly of a metal-plastic pipeline, use dismountable and non-separable fittings. Threaded installation of plastic pipes allows you to disassemble the entire system at any time, but the consumer will have to periodically twist the nuts on the fittings to avoid leaks.
With the use of press fittings, a reliable butt joint is obtained, but for its production it is necessary to have a tool such as special press pliers, which we make by crimping the pipe with the fitting in the press sleeve.
The installation of the water pipe in the installation site can be done in two ways:
- assemble the entire system with fittings and then fix the plastic pipes to the wall with clamps or clips;
- install a pipe mount on the wall and mount a part of the pipeline on it and only then connect it to another part of the structure.
Fastening a plastic pipe to a wall or ceiling is a very simple procedure, and its execution does not require any skills or special tools. It is not necessary to call for the help of professionals, you can do everything yourself, by spending a minimum of funds and efforts.
