Clean clogged sewer quickly
What to do if the sewer is blocked? Simply remove the siphon under the sink and then go with a hose (at least 50 mm) from the wet vacuum to the drain pipe. Seal all other inflows and switch on. In a flash, the tube is free.
Advantage: The fact that the whole dirt is removed so to speak backwards, you get the pipe from the inlet to the point where it was clogged, really clean.
Has even worked for me with a broken ground line. Sand had penetrated the sewage system outside the building due to a sleeve offset / sinking and sealed the pipe. This sand then worked like a "sandblast cleaning" in the pipe during suction.
