This is in a cottage and there is no way to get to the plumbing underneath the shower. I can see it but I can't get to it (insanely tight crawlspace)
It's a problem. My guess is that is has been leaking since it was installed or maybe since the floor framing was braced and leveled.
The shower drain fitting has pulled away from the drain pipe and there is a gap. Of course a lot of water is leaking. In the closeup picture you can see the problem - the pipe is supposed to be up in the black collar in the drain. I thought I could simply push the pipe up from underneath and either strap it or brace it so it wouldn't drop again. Problem is that it's attached directly to the 3" main drain line and there is no movement whatsoever. And it is not accessible.
Are there any sneaky ways to fix this from the the shower end? The drain pipe is 2" ABS.

your best way to fix this is to call a plumber....
