The main sewer line in my daughters cellar suddenly started leaking. The house was built in 1860 and has a ‘hung sewer’. That is a sewer line that exits the house just a couple of feet below grade level. The coupling in question is 4” and is part of a clean out that was added. Someone removed a section of pipe. Installed a new section with clean out and fastened it together with a pair of rubber couplings.
yesterday, I did what I usually do and just tightened the hose clamp. Today, there’s still enough of a drip to maintain a 1.5” puddle on the floor.
One big question I have is why after many years, the fitting started dripping. I have no answer.
without taking it completely apart, I can think of two courses of action:
1. Add another clamp.
2. Loosen the clamp and work some plumbers grease in there.
suggestions?
