I need to replace a leaking section of 4" of main cast iron sewer pipe. (its actually slowly seeping around a hub connection (on hub side)).
The pipe is hung at about shoulder level and is easily accessible. The minimum replacement length is probably about 2-4 feet.
I've been reading about the options and my head is spinning..
Schedule 80 with no-hub shielded coupling - thicker walls to reduce noise (the replacement section is under bedroom), but also thicker walls that reduce the ID. But is it really thicker than Cast Iron, especially considering all the crust inside?
Schedule 40 - standard, larger ID, more noise from rushing water?
Cast Iron - one to one match, but so many people say go with PVC, replace as much as possible.
I can somewhat easily replace about 20 feet of cast iron (from one existing coupling to another, with a 90 degree bend between two 10s). Should I be doing that? S40? S80? DWV?
please give me some pointers on direction!
Thank you!
