If you go to any hardware store in L.A., seems like all the drain stuff is ABS, and PVC is just for sprinkler systems it seems. I am not sure why that is, but you don't really see PVC on drains around here. Anyone have any idea why this is?
I want to use a Watco Flexible Waste/Overflow on my tub, but all the fittings on it are Schedule 40 PVC, they don't have an ABS model. I'm going to use it anyways as it's the perfect solution for my tub, but I need to connect it to female threads on a 50-year-old 1-1/2" cast-iron trap. The drain will be pretty much inaccessible once the tub is in place, so I need to glue everything apparently.
These are my options are far as I can figure:
1) Screw an ABS nipple into the cast iron, then connect the ABS nipple to the PVC using a banded coupler. Problem is, the drain will be practically inaccessible once the tub is installed, and I am not sure it's OK to have a banded coupler inaccessible as it's not glued.
2) Screw a PVC nipple into the cast iron (if the threads match, not sure if they do) and then glue the drain assembly onto it. This seems the best solution, but I'm not sure if PVC is OK to connect to cast iron.
3) Break up the concrete, replace the cast iron trap with a PVC one (if i can find one here in L.A., doubtful) and glue the drain assembly to it. Really not keen on doing this but will if it's the best thing to do.
Any thoughts? Mainly want to do this right so I don't have leaks and such. Thank you.
