How to install PVC sewer pipes yourself

A few cubes of aggressive liquid flow through the sewer pipes daily. There is nothing surprising in that, over time, the pipes become unusable and need to be changed. New PVC sewer pipes are a good solution, both for a standard apartment and for a home.

Lightweight, low price and easy installation - speak in favor of sewer pipes made of plastic for an apartment or house. A wide selection of accessories and components allows you to carry out the sewage route configuration of any complexity. The warranty service life of sewer plastic pipes is about 50 years.

Advantages of plastic sewer pipes

Installation and assembly of sewerage from PVC pipes, on forces to produce independently to any owner. Light weight, allows you to hold the track and fasten the pipes on plasterboard walls or piers.

1. PVC pipes are easy to disassemble for cleaning and also easy to assemble. There is a mass of all sorts of knees, tees and revision inserts with different degrees of bending. The smooth internal surface of the pipe has a high throughput and is not susceptible to overgrowth.
2. PVC pipes are dielectric, they are not afraid of wandering currents, destructively acting on the metal. They do not suffer from corrosion, they are resistant to acids and chemically aggressive environment. Low cost, combined with operational durability, explains the high popularity of PVC sewage pipes.

Dismantling of cast iron and the installation of plastic sewerage

Dismantle the cast-iron pipes and install new plastic, you can even single-handedly. A turbine, a sledge hammer and a chisel with a hammer - the entire set needed to replace the sewer pipes.

1. It is possible to dismantle the cast-iron pipes of a sewage pipeline with a turbine, with a disc for metal or welding. In the areas of docking, a vertical cast-iron pipe, deep incisions are made by the turbine. Then, the pipe is smashed with a sledge hammer. The remnants of the joint, tightly stuck in the docking socket, are removed with a hammer and chisel.
2. An adapter to the plastic pipe is inserted into the docking-iron casting bowl. It consists of rubber cuffs and a plastic branch pipe. Further lay the pipeline in accordance with the plan. The main pipe has a diameter of 100 mm, and for a kitchen sink, sink and bath tube is quite enough 50 mm.
3. Note the slope when laying the track. If you take the output of the central sewer pipe as zero degrees, then the starting point should rise by about 30 °.On the road there should be no slack in which water can stagnate. Bends and turns of 90 ° are permissible, but it is desirable to reduce them to a minimum.
4. Vertical cascading transitions do not significantly affect the patency of the sewage system, but the optimal option for the route is a straight line. At key locations, install inspection inserts to clean the sewer pipe. These are such branch pipes with an outlet and a screw cap. In the case of blockage, it is easy to reach the mud plug with a vibrating bow or elastic steel wire and punch it.
5. When assembling the sewer pipe, the ends of the pipes can be lubricated with engine oil, technical petroleum jelly or solidol. So the pipes are much easier to assemble. Some masters use water resistant silicone. It not only eliminates excess friction during assembly, but also gives additional sealing to joints.

Connection of plumbing to the central plastic pipe

In the places of connection of domestic sanitary equipment during installation, tees are put. If the main pipe or riser has a diameter of 100 mm, then for the bidet and the kitchen sink are installed a tee 100x100x32 or 100x100x40 mm. For a washbasin and a bathroom the standard issue is 50 mm, and for a toilet - 100 mm.

1. Often used for plumbing corrugated exhaust pipes. This is not only convenient for installation in hard-to-reach places, but also convenient for preventive cleaning during operation.
2. Connections of plumbing exhaust pipes with sewerage system, is carried out with the help of sealing gums. In case of poor connection and leakage, it can be removed with a waterproof sealant. When installing and installing the toilet, the outlet is additionally cemented.

Installation of plumbing in the house

Laying sewer pipes in the house will require additional work on digging a trench to a sewer well or tanks with a septic tank.

1. In a new house, the main sewer can be "drowned" in the floor. For the release, during the laying of the foundation, a metal sleeve is made at a depth of at least 75 cm. From the basement, to the sewage well, a trench with a smooth groove in the direction of drainage is digging. The slope, approximately 30 °, will be quite sufficient.
2. The laid external sewer pipes in the trench are additionally insulated. In normal operation, the water in the pipes is not delayed, but in case of blockage, during the winter time, there may be a frost. Sewer pipes PVC can not be thawed open fire. Only with boiling water or with care, with an industrial hair dryer.
3. For insulation of plastic sewer pipes, use polystyrene foam, mineral wool or any other insulating material that is not susceptible to putrefaction in the ground. There are special flexible tension heat insulation hoses based on polyurethane. The pipes are put on a heating sleeve, then the sewer pipes are assembled and laid in a trench.
4. In the sewer, in the masonry wall, an opening is made into which a metal sleeve is inserted, the diameter of which slightly exceeds the diameter of the sewer pipe. The site is carefully reinforced with stone and brick, and then cemented. A PVC sewer pipe is inserted into the sleeve, its outlet should be 25-30 cm.
