I need to join a 3" ABS pipe from the toilet to a 3" PVC sewer pipe under a concrete slab.
OD for PVC is 3.25" approx, and 3.5" for ABS. What is the best way to do this?
It was glued before but leaking. If I'm using glue again I'm planning to use a standard 3" ABS coupling with an ABS bushing adapter as a reducer to connect the PVC pipe. Is it correct? (I'd use transition cement (PVC to ABS) to join the PVC pipe to the ABS bushing)
I can also use a Fernco but I don't know which one (model?) AND if I should use a PVC bushing to increase the OD for the PVC pipe.
Thanks.
