I have a septic system that drains out from the basement wall. The drain pipe follows the wall and then goes down a long radius clean out and connects to a "no hub coupling" that connects to the pipe that exists the basement wall to the holding tank. The pipe end from the clean out tee pulled away from the coupling and started leaking. It was easy to notice as the previous owner painted the ABS pipe white so you could see the exposed black of the pipe that pulled out. Because the pipe that exited the wall was sealed with hydraulic cement and some of the cement was on the coupling and it was all painted white that I assume it has been this way since house was built in 1987 and we didn't move in to 2005 and have done no work on this. I have since cleaned off some of the cement. I can't understand why the pipe with the cleanout now pulled away from the coupling?
I was able to loosen the coupling and push it back in. However, I noticed that the pipe that exits the wall is at an angle that the two pipes don't align up flush. In fact, the rubber seal in the coupling has a center in the rubber seal to push the pipe up against and when there connected, the angle of the pipe exiting the basement wall could not be pushed in all the way flush to the center and was angled so that the top part of the pipe could not be up against the stop inside of the rubber membrane. It is about a 1/8-1/4" short of going all the way in. This is because the pipe exiting the wall is angled downward as it flows outward and won't align with the inside pipe as that is at a flatter angle.
Any ideas of why after 30 years the pipe pulled away?
