best drain fitting for acrylic shower pans?
i removed the shower pan last night and found that there probably wasn't enough mud to support the whole pan adequately. Also, there are 1x3 ledger boards to help support/level the pan and lastly, as you mentioned, the subfloor hole was pressing against one side of the pvc pipe. So i plan on opening that hole up around the pvc drain pipe and using more deck mud to bed the pan.
Lastly, i would like to replace the drain fitting in the shower pan with one that fits inside the 2" pvc pipe and that doesn't require pvc cement to make the seal, as would one that fit outside the PVC pipe? The type i had in there before had a brass body and a neoprene "V" gasket that fit around the pvc drain pipe to make the seal. It seams like just a matter of time before that seal gives out? Although it was nice when trying to remove the pan, as it presented little resistance when we lifted the pan. This is a new install so i can't say whether the drain fitting was leaking over time. I did do a few buckets of water in the pan when is was installed and no noticable leaks, although the celing below is finished, so it might take quite a significant leak before i noticed it through the celing plaster.
Any recommendations for fail-safe drain fittings?
