How to crash into a plastic pipe

Ways to tie into the sewer

You can connect to an existing sewer pipe using a special tee if the system is metal. In modern plastic systems, this method can not be applied. To hurry with the decision of this question it is not necessary. It is necessary to consider various ways of tapping into the sewage system and then begin work.

Insertion using tee

This method is somewhat troublesome and requires great accuracy in the selection of the tee. To begin with, cut out a piece of pipe and very precisely pick up the tee, which will replace the cut out part. When planning work, remember that the tee will be fixed in the form of a coupling, and after that all the joints should be welded. Independently with this work can hardly be managed, unless you are a professional welder.

In the event that the sewer pipe is plastic, it is possible to replace one part of the common pipe with a pipe already prepared, specially designed for connecting additional household appliances. The main problem will be the connection using the sockets inserted into the pipes.

Insertion into a plastic pipe

It is possible to cut into a sewer pipe in a very acceptable way, which will be able to any master. To do this, perform the following actions:

1. The most important thing before work is to warn neighbors so that they do not use plums.
2. Prepare the pipe in advance with a suitable diameter pipe.
3. Cut the workpiece, i.e. Leave the branch pipe with a part of the pipe of this size so that the cut-off point in the sewer pipe is reliably blocked.
4. Next, a hole is drilled in the sewer stand that is identical with the diameter of the branch pipe.
5. The inner surface of the obtained flange and the outer surface of the pipe around the hole are abundantly lubricated with a sealant.
6. We put the flange on the pipe, tightly pull it along the edges with the use of clamps. We'll have to calculate the forces to tighten everything not very tightly and accurately, only to have a sealant on the edge, the excess of which is removed. If the water pressure in the sewage system is low, the clamps can not be used, you can use insulating tape.

Cutting into a metal pipe

In a metal pipe, the tapping is carried out using a finished tee with a diameter slightly larger than the diameter of the main riser. It is not always possible to purchase a tee of the required parameters, sometimes you have to prepare the flange yourself:

1. It will take a pipe to have its internal diameter identical to the outside diameter of the sewer pipe.
2. The pipe should be cut along, drill a hole in it and weld a branch pipe.
3. This work should ideally be done by professional welders. If it is not possible to weld the joint, then use clamps and sealant.

Insertion is similarly allowed in heating pipes, water pipes, sewerage.

What is needed for tapping into the sewer pipe

Currently, there are quite a lot of various adapters in the construction market, flanges serving as transient devices. So for any problem you can easily find a solution. For example:

• for pipes with a diameter of 100-110 mm are put adapters, having a diameter of 50 mm;
• for pipes with a cross section of 32-40 mm fit tie diameter 19-22 mm with plastic fitting.

A qualitative insert into the sewer stand will avoid dismantling and complete replacement of the entire riser.
