I am relocating my bath tub. I need to move the drain (which is under concrete slab) approx. 2' at 90 deg. angle. The drain is 2" abs. My problem is that there isn't enough clean abs for new fitting. These is a 4" long piece of pipe that runs between the 90 which goes into the p-trap and a T which is also used for vent. This 4" piece of pipe has a larger piece of pipe (u shaped) glued to the underside of it (I assume as a stiffener). The guy at the big store suggested that I cut the 90 (which goes into the p-trap) at the collar and clamp a 2" rubber coupling onto it. This is what I did but do you agree? I am desperately trying to avoid having to go way under the slab to find a clean piece of pipe. fyi the T that is used for the drain/vent is up against the slab and under a supporting wall.
