Concrete sewer pipe
Author: PREZ (MT) I am installing clean outs in my sewer line. Wasn't exactly sure what the line was made of before digging down and thought it was cast iron but turns out it is 6 in (id) concrete. My question is do I need install 6 in pvc sanitary tees and pipe for my clean outs or will 4 in pvc work. As an alternative, would fernco flexible pvc tap saddles work?
