This job is relatively simple when visit stamps have been mounted on the network. Otherwise, it will cut the pipe to add.
Check that the installation has a tee corresponding to the section to be opened or cleaned.
If this is the case, unscrew the cap.
Insert the ferret wire into the pipe to the plugged area, then rotate the cable with the wooden handle.
When the network does not have a tee, you must install it yourself.
Start by identifying in pencil the accessible place to place the tee.
Follow the route and cut the pipe at the chosen location using a hacksaw or pipe cutter, perfectly adapted to work in place.
Release the hose from its clamps to facilitate the installation of the inspection tee.
Glue this fitting and then snap it onto a first section of pipe.
Leave to dry for 10 min.
The tee is well glued to the pipe, fit it and fix it in the same way on the second section.
Allow to dry 10 min before continuing the operation.
You can now push the ferret cable into the pipe into the plugged area by the tee you just placed.
The cable has penetrated sufficiently inside the pipe, turn it with the wooden handle to unclog or clean the installation.
When the operation is complete, all that remains is to screw a cap on the opening of the tee.
It can be used if the pipe clogs again.
