There are situations when sewers impossible to bump with a tee. For this there are special linings on the pipe. The essence of this lining is that for tie-in sewers do not need to cut a pipe segment. Let's take a look at this sidebar in more detail:

  1. Buy a pad of the same diameter as the pipe to which you will connect.
  2. Cut a window in the pipe, and clean the edges of the cut-off from agnails.
  3. Grease the edges of the window with a sealant and put on the cover so that the drainage system coincides with the window on the pipe.
  4. Attach the cover with clamps, and twist the cap on the drainage.

This method of tie-in is considered an emergency one. After all, the window size is impossible to fit perfectly to the size of the drainage system.Consequently, dirt will cling to the protrusions, and deposits will accumulate. But if there is nowhere to go, this method is also good.

This completes the details of the tie-in, you can safely get to work.
