The main 4" PVC line coming into my poured concrete wall in the basement apparently settled and the pitch became more steep. This pushed the end of that pipe just inside my basement up and the 90 degree elbow cracked. The plumber recommended digging outside and putting in a couple of elbows that would provide some leeway to adjust the pitch properly. l can see how that would work except I'm a little worried about the bends increasing the chance of a clog.
I was looking around on the net and saw they do have 11 degree elbows , which I suppose would help (rather than using 22.5). In fact, the pitch change is pretty noticeable and may even be close to 11.5 degrees.
I can't really see an other solution except digging the whole thing up. I'm not sure if the root cause was the main sewer line at the street falling down a few inches. I may check with my neighbors!
This elbow in the basement also has a clean out on it which he recommended moving outside which made a lot of sense to me.
Any thoughts on this?
