Close waste water pipe

A sewage pipe that is no longer required does not have to be torn out of the wall. You can seal it to keep gases from leaking out. There are socket plugs in the hardware store with which the sewer pipe can be sealed gas-tight.

What should I do?

First you need to determine the type of sewer pipe and its nominal size.

  • HT pipes are laid in the house as sewage pipes, nominal sizes DN 40, 50, 70 or 100.
  • KG pipes are laid in the ground or under the basement floor, nominal sizes DN 100, 120, 250, 300, 400 or 500

Obtain a socket plug for the corresponding size and type of sewer pipe from the hardware store. Insert the stopper according to the manufacturer's instructions.
