How to bump into a plastic sewer pipe

Before connecting the pipeline to the existing sewage system, it is important to take into account many nuances - paperwork, system design, material selection. With independent work, you need to study the technology of connecting to vertical and horizontal risers.

Sewer Tie

Reasons for unplanned insertion of the pipeline into the existing system:

• Connection of household appliances (washing machine) or plumbing equipment. The new site is led to a local sewage system.
• Kitchen connection.
• Insert of the built house into the system of the microdistrict or village. Pipes lead to a sump (horizontal branch) or a riser uniting several houses or apartments.

Since it is not possible to ensure the absence of wastewater during the work, it is important to use special protective equipment.

Preparatory stage

When choosing components for the sewage system, it is necessary to observe the basic rule - the pipeline going to household appliances and sinks in a horizontal line should have a most obtuse bending angle. It is important to consider the location of the toilet outlet - it can be installed in an inclined position or in a horizontal plane, at an angle of 45 degrees to the floor surface.

When trimming the riser during the day, it is better to first ask the neighbors on top not to use the plumbing equipment for several hours. Necessary tools and materials:

• Grinder or hacksaw. During assembly, these tools are required for trimming metal or plastic. When choosing a saw, you need to choose a blade with a small tooth.
• Crowns. To insert incoming elements into a pipe with a diameter of 110 mm, a hole of 50 mm is made. For plastic, cheap products of the specified size are suitable. The cast-iron riser is treated with a conventional metal drill.
• Wrench.
• Sandpaper or file. When trimming water pipes, you must remove the burrs remaining inside the product.
• Sealant.
• Adapter for tapping into the sewer.

When choosing tools, it is worth considering the material of the manufacture of pipes.

The main methods of tapping into a sewer pipe

Do-it-yourself tapping into the sewer is possible due to the presence of sealing couplings and adapters. The easiest way is to install a tee. For repair, you will need to remove a small section of the sewer. A tee is placed in its place, and the joints are isolated. The cut-in section must have the same diameter as the pipeline. This method is mainly used for metal systems.

You can crash into a plastic sewer pipe in the following ways:

• With fittings. The riser is first cut, then a tap is threaded and fitting connections with bends are installed.
• Using an adapter with a cross section of 5 cm2. It is used for pipes with a diameter of 10-11 cm. When connecting the pipe, it is necessary to free access to the sewage system, determine the distance from the drain to the inset, cut a hole with a crown of the corresponding diameter. The seat is treated with sealant, then the adapter is installed and the fixing nut is tightened.

You can make an insert into the cast-iron sewer pipe in the presence of a segment of similar communication. Features of branching in this way:

1. Using a drill with a bimetallic nozzle, drill a hole in the riser. No chips should remain at the treatment site - it can damage the pipeline.
2. Clean the hole of metal debris, dirt and grease stains.
3. Paste the prepared item into the communication. It is important to observe caution - with deep placement of the adapter, an obstacle to drains is formed.
4. Weld the pipe adapter to the line.
5. Treat the weld area with an anti-corrosion compound.

The methods of tapping into the sewer differ depending on the location of the riser:

• Vertical. Before connecting household appliances or plumbing fixtures to the PVC pipe, it is necessary to free the pipeline from the fasteners to the walls, cut the pipe section with a grinder according to the size of the compensator, clean the edges with a file or sandpaper, put the upper end in a bucket. Then the trimmed ends of the riser are treated with grease, the adapter sleeve for the tee is put on the lower one. On the upper end put on a compensator and move it all the way. It remains to lower the compensator until it is firmly fixed in the socket of the tee and fix the riser.
• Horizontal. In this embodiment, a slip clutch and a compensator with a pipe located at an angle of 45 degrees to the pipe are used for connection.

When tapping into pressure sewers, conventional adapters for PVC pipes are used. If you need to connect a plastic and cast-iron pipe, use a rubber cuff.

Saddle

You can connect the plumbing to the riser with the help of a saddle - a pipe part intended for a branching of sewer systems. The element is universal and can have different diameters. It is made of cast iron, plastic or steel.

The saddle-wheel significantly simplifies and reduces the cost of installing the piping assembly. When inserting it, the integrity of the sewage system is not violated - it is enough to drill a hole of the required diameter in the pipe. Using a saddle, you can connect to the sewage system anywhere. There are several types of such structures:

• Crimp. Presented in the form of a clamp clamping the pipe from 2 sides. One of the parts of the product has a threaded bend that allows you to install transition elements on the plumbing sewer. Mount crimp saddles with nuts and bolts. The tightness of the connection is provided by the sealing ring. Such products are used in conjunction with asbestos-cement, polypropylene and polyethylene pipes, PVC models. The maximum carrier temperature for crimping saddles is 40 degrees.
• Electric welded with a mill - designed for pipes PND. They are installed using electrodiffusion welding, which implies the presence of a heating coil in the lower part of the patch part. Under the influence of a current of a certain power, its temperature rises, and after cooling the saddle branch with a pipe become a single element.
• Branch pipe. Such models are divided into 2 types, one of which is equipped with a locking mechanism or a special cutter. Installation of the product can be carried out with a working sewage system.

When using the saddle, the insertion into the riser is facilitated, since the part has many varieties.

Sewer Inset

For the accumulation or filtration of wastewater, sewer wells are used, into which all elements of the sewer network are reduced. Features of the insert into such structures:

1. A hole is made in the place where the pipe enters the well. Its diameter should exceed the cross section of the input communication. Plastic products already have corresponding entries.
2. For the differential well and septic tank, the pipe is cut flush with the inner surface of the tank wall.
3. When making communications from cast iron, asbestos cement or ceramics, they must be concreted into the hole.

The pipe must enter the well above the drainage level and have a certain slope.

Responsibility for unauthorized insert

Self-inset issues are governed by Art.7.20 Administrative Code of the Russian Federation "Unauthorized connection to centralized water supply and sanitation systems." The punishment for unauthorized connection to the riser involves the following fines:

• 1-1.5 thousand rubles - for individuals;
• 2-3 thousand rubles - for legal entities.

A fine is not the largest expense item for illegal tapping into a sewer. Violators have to pay:

• Services for using the system for a period of 6 months prior to the date of detection of an unauthorized connection.
• Dismantling of illegally installed elements.

Since the sewage system is a complex and costly process, it is better to immediately legally connect to the system.

If an illegal connection is detected when buying a home, you should immediately report it to the service company. In this case, fines are not threatened by new homeowners. However, if a tie-in is discovered during the inspection, sanctions may follow. You can challenge them when you go to court.

You can legitimize the existing connection when buying a private home yourself. It is first necessary to eliminate the installed elements, and then apply for the sidebar. However, this can lead to accidents or conflicts with neighbors. It is worth contacting the utility service, because dismantling may not be necessary if the connection is made in accordance with SNiP.
