I had a new shower pan installed and the drain plate looks like it is not seated flat. It appears that there is a rubber gasket right below the drain plate. I would normally call the installer back but he did such a crappy job remodeling our bathroom, I never want to see him again. Found out he was on meth. Anyhow, does this drain plate unscrew? If so, should I use a sealer besides the rubber gasket?
If Marty can answer my questions in post #21 I may have the solution. Its an Oatey for sure but which one. Some acrlic pans, like Swanstone and Florestone, use a special sleeve that is driven down over the 2" PVC and between the shower sump making the seal. That larger black washer may not even be needed. Look at his pics, I think I can see the sleeve between the pipe and the gasket.
I think it is regular fat washer that fits over the pipe and is squeezed down, and against the pipe with notched, large, black plastic nut.
Just to make one thing clear: Of course, there is another black, plastic nut under the pan holding the drain against the pan itself. Just like the one Tom posted in his post #5.
Either one's acceptable. We always used plumbers putty but then I've been retired for over 20 years. Milo's trying to let you down easy. Your plumber goofed and installed the drain wrong. There is no simple repair. The floor must be opened up and the drain reinstalled correctly. Good luck, Tom
I'm not a lumber but I have had silicone peel away after a wile so I am leaning towards the putty. Maybe there is a good silicone product out there that I am not aware of.
It peeled off because the surface it was applied to was not clean. We use Denaturated Alcohol in spray bottle. We spray the area with it and wipe it clean and dry with clean terry cloth. Only then we apply silicone.
Problem with putty application in your situation is that putty will not hold the drain down to the pan. Silicone will. Once remove the rubber washer you will have a large gap left. That gap has to go. You will have to push the drain flange down after you apply silicone, put weight on it, and leave it there for 72 hours minimum to dry. Only then you will have good chance for positive seal.
Remember, you cannot get under the pan to tighten the large nut to pull the drain body nice 'n' tight against the pan.
Actually, a drain did not come with the Lasco pan. We got the plastic Oatey drain at the hardware store. Hopefully it is the one that doesn't need the rubber washer. Thank you for the info. This answer refers to Ballengerb1's answer earlier.
