Help Troubleshooting Drip from Newly Installed Shower Pan and Oatey No-Caulk Drain

[DIYCHASE]

I recently installed a Delta shower pan along with an Oatey Round No-Caulk Black ABS Shower Drain (4-1/4 in. with stainless steel snap-in cover). When I tested the pan and drain for water retention, I noticed a small drip (see attached video).

The drip seems to originate near the connection between the drain pipe, the no-caulk barrel, and the rubber pipe gasket. I’m trying to figure out if it’s clear what I might have done wrong.

• Could it be that I didn’t tighten the locking ring enough?
• Is it possible the rubber pipe gasket isn’t seated correctly?
• Or does this align with any other common issues you’ve encountered?

For context, I followed the manufacturer’s instructions for both the pan and the drain to the letter. Any insights or tips would be greatly appreciated!

I considered using Great White Pipe Joint Compound between the end of the pipe and the rubber gasket but I saw a warning in the installation instructions that said "Do not use oil base sealers on any plastic No-Caulk Shower Drains, because it may cause assemble to break or distort. Only use an A.S.T.M. recommended silicon sealer."

Bumping this.

I actually am having this same issue I replaced the gasket and got it seated better but still after running the shower for ten minutes I got a small drop of water.

Did you ever figure out the issue?

I'm doing a gut remodel of a few rooms, so bouncing around a little bit. Haven't gotten this figured out yet, but been distracted.

The next step for me based on feedback I'm getting is (1) make sure the rubber gasket (bevel side up) is pushed as far down as it can go, as it might not be tight enough against the base of the no caulk barrel then (2) use this tool to tighten down the gasket screw. I used a Phillips screwdriver and all my strength to tighten using the wrench that came with the kit, but I've heard it from a few people that you need to be a bit more than hand tight will get you (12" or 14" crescent wrench on that tool was the recommendation, but don't go crazy on it).

If this doesn't work, I will follow this advice " I’d remove the gasket set screw as well as the rubber pipe gasket. If you look inside pipe after removing gasket, I’d believe you should see the top edge or lip of drain pipe. Take the oatley great white pipe dope and generously coat this area. It also couldn’t hurt to coat the bottom edge of pipe gasket as well as lower outer side that would make contact with pipe. Put it all back together and tighten up and test"

The instructions specifically call out not using an oil based sealant like the one advised there, but I've talked to a few plumbers that say it is highly unlikely the sealant will do damage within our lifetime.

I'm not a plumber. I did install an acrylic tub and the instructions for it said to use clear silicon on the drain to seal it to the tub. Your results may vary.
