This is my first post although I've used this forum quite a bit for a lot of good information. Thanks!
Installing a Delta Classic 400 Acrylic Bathtub and I have a couple of questions about sealing the drain. In the instructions it says not to use plumbers putty which I've read about in the past. It says to use a polymer sealant and give three recommendations: DAP 3.0 Kitchen, Bath and Plumbing High Performance Sealant, Red Devil RD 3000 Advanced Kitchen and Bath Sealant, and ECO-BOND Kitchen, bath Plumbing Adhesive Sealant. I called the manufacture to verify that these are the sealants they recommend for the drain.
1) I've never heard of using these kinds of sealants on a drain before. On acrylics, Silicone has always been recommended. That includes on this site. I've also read that I should always follow manufactures directions. Should I use one of these or just use silicone?
2) This bathtub has a black plastic supporting framework underneath the tub which is supposed to eliminate the need for a mortar bed. That's good however it also surrounds the drain opening. Meaning a cross-section would show the tub bottom, then a gap, then the black plastic. If I install the drain/overflow kit as normal the drain ell will be up against the black plastic support NOT the tub bottom leaving a gap between the support and the tub. Meaning the rubber gasket is actually not touching the bottom of the tub. This gap closes when I tighten the drain but there is not a gasket in there. I thought that the bottom gasket was the real seal here. Anyone have any experience installing these types of tubs? Below is a picture of the framework.
Thank You!
