I'm preparing to replace a bathtub and the new one requires a different drain assembly (the overfill drain is a wide-mouth connector).
Anyway, I'm noticing that the new drain pipe material itself is different - a white plastic (PVC?) compared to the old drain which is a black plastic (not sure what it is).
Is it OK to mix these two types of materials? I seem to recall that some plastics can't be interconnected together or that a special glue is required.
If it IS OK, what type of sealant should I get? Just a standard silicone glue?
