When attaching a drain fitting to a plastic shower base, should I use
some kind of adhesive or are the 2 cork pieces provided for either
side of the connection good enough?
Plumbers puddy? Calk?
I like clear (or white) silicone caulk. Apply just a thin film
on both sides of the top gasket.
The base should be supported on a bed of cement to prevent it flexing
which will soon break the seal at the drain. If possible, inserting
a rubber "Mission" (Fernco) coupling in the drain line will provide
a little "give" and allow a bit of flexing.
from my experience, more often than not the 'more is more' theory backfires
with plumbing. overtightning can cause leaks. introducing caulk or other
substances to pressure fittings can cause leaks. its 2004 and they've
pretty much got shower drains figured out so they dont leak. just do what
the instructions say.
