Installation of sewerage in a private house

It is not difficult to run a sewer in a private house. Heavy physical labor is only necessary when digging a trench. Modern plastic pipes are easily assembled and assembled under the condition of a properly designed project. The sewerage project in a private house is coordinated in Vodokanal.

Based on the project, the required pipe, fittings and components for seweragein a private house, a photo of some necessary details is located below. See the process of sewerage installation in a private house, the video at the end of the article will help you.

Types of pipes for sewerage in a private house

It is not difficult to choose pipes for sewerage installation in a private house. The trading network offers a lot of options for pipes and accessories for them to choose from.

1. Cast-iron sewer pipes - traditional in plumbing and time-tested. Mount them quite difficult, they have considerable weight and cost, but the sewage system of cast-iron pipes is installed for a long time. Cutting or reworking without dismantling is quite problematic. Over time, caverns and shells are formed on the inner surface, on which growths are formed, contributing to blockages.
2. There are several types of plastic pipes. Polyvinylchloride( PVC), durable and inexpensive. Gray pipes are available for internal wiring and orange for outdoor. Polypropylene( PP) pipes - heat-resistant flexible corrugated pipes. Polyethylene( PVP) - have high strength and flexibility. Fiberglass pipes - reinforced with fiberglass.
3. All sewer plastic pipes have low weight and low cost, and the presence of a large selection of nodes and fittings allows you to sewage of any complexity. Guarantee period of operation of plastic pipes is not less than 50 years. High patency and the absence of blockages when properly used justify the popularity of plastic sewage.
4. Ceramic sewer pipes are less common, but they also have a number of advantages. They are made from clay with the addition of kaolin or chamotte and baked at high temperature. The nozzles are coated with polyester resin to seal the joint. The internal smooth surface of the ceramic pipes provides high permeability. Friability and weight are related to the shortcomings of such pipes.

Concrete and asbestos-cement are now practically not used in sewage systems. Bad performance and the lack of accessories say not in their favor. Therefore, it is reasonable to make a sewage system in a private house from modern materials.

Layout and installation of internal sewerage in a private house

. Draw a diagram - an internal wiring diagram for sewage installation in a private house. Mark on it the premises and plumbing objects planned for connection. The slope of the pipes to the central node is 1 cm per running meter.

1. Installation of the plumbing of a private house with your own hands does not require special skill. Pipes are cut to size and inserted into the socket. Experienced plumbers in the process of docking process the edge of the plastic pipe with fine-grained sandpaper and lubricate with a thin layer of solidol.
2. For the bathroom and ceramic washbasin, pipes with a diameter of 50 mm are used. For kitchen sink 40 - 50 mm. The toilet is connected to a pipe 100 mm in diameter. The correct wiring is laid from the kitchen sink through the bathroom to the toilet. At the installation site of the toilet, a mounting tee is installed, into which drain pipes of smaller diameter are built. From the toilet the road is taken to the street.
3. Autonomous sewerage in a private house is settled during construction. Internal wiring is recessed under the floor or under the wall. When replacing the sewer use old routes. In case of blockage, depending on the layout, sewer wiring is equipped with 1 - 2 revision tees. In this case, you do not need to disassemble the whole system for cleaning. It is enough to unscrew the lid and the system will be available for the plumbing cable.
4. Passing through the wall sewer pipes of internal wiring are fixed with plastic clips. In the wall holes are drilled for dowels, pipes are built up and fixed with special clamps. The distance between the clamps is 1.5 - 2 meters.

Connection of plumbing fixtures to the sewer system

For connection of plumbing units and instruments, tees with diameters of the desired diameter are inserted into the deck or riser and they are joined to the siphons.

1. Siphons are installed on the tub, kitchen sink and sink. Siphons are made of plastic or metal with a rigid or flexible drain hose, which is inserted into the socket of the tee of the sewage system. Sealing rubber rings give a good seal, and for reliability, the joints are coated with waterproof silicone.
2. Corrugated flexible outlet is more convenient for installation. It is produced in different diameters and applications. For kitchen sinks and washing machines 40 - 50 mm in diameter, for baths and ceramic sinks - 50 mm, for toilet bowls and bidets - 100 mm. There are special drainage systems for shower cabins and traps.

Laying the sewer from the private house to the

well. The sewage pipe from the internal wiring in the house is located in the foundation at a depth of 75 cm. In the event that it is technically impossible to locate the outlet at the required depth - the sewage pipes are insulated.

1. For mineral wool insulation, mineral wool, expanded polystyrene or other suitable materials are used. In the case of blockage in winter, without insulation, it is possible to freeze the route. Defrost it is quite problematic. It is necessary to open pipes and gently thaw with hot water or air. Plastic pipes can not be defrosted by open fire, and they buckle from high temperatures.
2. From the release in the foundation to the drainage well, a trench digs. The estimated slope is approximately 30 °.Avoid turns and vertical swings. Observation wells are equipped on the route every 10 meters. The correctness of the level of the trench is checked by twine strung on the bottom.
3. In the laying of intermediate wells and the end point, which is a drain hole or a central sewer well, metal shells are laid. The sleeves exceed the diameter of the plastic sewer pipe by 2 to 3 cm and protect it from deformation in case of a draft of the well.

In those situations where there is no central sewer nearby, the drain pit is equipped with a septic tank. This is a local wastewater treatment plant used in cottages or suburban areas.
