    Ok, so I got a toughie on my hands and hoping someone has a suggestion, because I’m stumped.

    I have a customer with a shower stall in a basement, on concrete. The shower drain has become loose. It’s been leaking for some time and has created extreme mould issues.

    Anyway, the person who installed it botched the install and now I’ve been called in for a solution.

    They used the Oaty push seal shower drain, but for some reason discarded the rubber seal that goes around the pipe, jammed a coupling in there and glued it. So now the top part will not turn so I can remove it and reseal the drain. To make matters worse, the fixture outlet pipe is hub to hub with the ptrap, so I can’t even cut it out.

    As a temporary solution, until I figure out a permanent one, I’ve caulked the drain. She has had two showers and luckily no leaks. But I’m stumped on how to make a permanent fix. Any suggestions would be greatly appreciated!

    Do you have any pictures, I am unfamiliar with that style of drain. The only drain I’ve seen that can be installed from the top only is a mustee showerbase that uses a resilient gasket between the pipe and a funnel in the base.

    I have used the three inch version on closet flanges with varying success, the two inch version might work to remove the coupling.

    Or use this to drill through the drain assembly and ream out the hub of the trap.

    Thanks Kevin



    What I’ve discovered since my original post, was besides the original installer botching the drain, the fixture outlet pipe was also too high and was pushing up on the bottom of the base and it actually cracked it. So the shower stall has since been taken out and plumbed properly.

    I find myself saying almost daily to myself “who did this?”.

    There used to be a good thread on here a lot of us contributed to a few years back about all the ridiculous plumbing problems we found. It should almost be resurrected.
