Hello,
I am in the process of renovating a bathroom necessitated by a crack in my old FG Bath/shower unit. I have bee wanting to replace the bathtub with a shower.
It is my understanding that 2" piping is required by code for a shower. The bath was plumbed with 1-1/2 as standard(almost seems like it might have been 1-1/4" on the metal part of the drain.
If you look at the picture attached there is 1-1/2" abs pipe going into the P-Trap. The P-Trap itself appears to be a 2" based upon specs for 2" ABS DWV fittings (O.D 2.38"). However it also appears that the P-trap is 1-1/2" on the house side and 2" on the outboard side. You can see in the picture that the union to the 1-1/2" pipe has a thick wall to it, and feeling in the hole I can detect a much thinner union wall.
Question: do they make reducing P-Traps? I suspect I have 2" lines at the P-trap and 1-1/2" above. I want to install a shower AND I want to be in compliance with code. I need to get some things cleared up before proceeding, and chipping out concrete and breaking apart drainage piping.
