Advantages of using plastic pipes.
With a huge variety in the construction markets, in the manufacture of plastic pipes, materials such as polypropylene and polyvinyl chloride are predominantly used. Advantages of such pipes are their durability, strength, anti-corrosion properties, as well as ease in carrying out connecting and fastening works. 
Unlike old metal pipes, gradually disappearing into the past, they are replaced by quality materials that are becoming increasingly popular in the manufacture of various sanitary equipment. The use of such structures has a number of advantages:
- A low price, which is one of the main factors in choosing;
- Excellent moisture resistance, which avoids the effects of corrosion;
- Resistance to small changes in temperature( at low values, they need to be insulated);
- Weigh about 5-6 times less than other samples;
- Absolutely non-toxic, practically do not burn.
There are some differences when it comes to laying outdoor pipes or indoors. The former have the ability to easily withstand the effects of low temperatures, and also are more durable in composition.
Preparing for installation.
Before starting the installation work, think carefully and plan your further actions.
- Step one.
Draw a drawing of future communications. - Step two.
Think about what you need tools and accessories. - Step Three.
Pre-purchase the required number of pipes and fittings to them, so that there is no downtime. - Step Four.
If you plan to install additional household appliances, prepare a separate branch for drainage in advance. - Step five.
Before cutting the pipes into pieces, carefully calculate their dimensions, including the diameter and length of each piece;
Plastic sewer pipes are cut with a metal hacksaw at an angle of 90 degrees. Slicers are cleaned from the burrs with sandpaper or a sharp knife.
Installation work.
Beginning the installation of sewer pipes, remember that they must have a degree of slope - this will facilitate the flow of liquid waste.
The second important aspect is the dimensions of plastic pipes for sewage, and more specifically the diameter. To ensure that the sewerage is not clogged with various garbage or human waste products, the pipe outlet, for example from the toilet bowl, must have a diameter of at least 10 cm. If the pipe is connected to a washing machine, but it will be much smaller diameter. Among themselves all these details are connected by special tees.
By the time the sewage system can be assembled from several hours to several days, it all depends on the skills of the master and the total length of the communications. Mounting the pipe to the fitting( adapter) is as follows: the edge of the pipe is inserted into the adapter until it stops( all parts must be clean without mechanical damage).On the other side of the fitting, a piece of another pipe is inserted and so on. 
Sealing of the joints is carried out by means of a rubber gasket( sealant) located in the connecting part. Sealant must be moistened with special lubricants, which are sold in any sanitary ware shop. If you do everything right, you can avoid trouble in the form of leakage or bad smell.
Another important point is the fixation of pipes using fasteners.
Observing all these rules, in the end you will get a quality and durable sewer construction.
