I have a leak in an upstairs shower. I've traced the problem to the
seal between the drain and the shower floor. There is a flange at the
top of the drain that meets the shower floor. There is a gap between
this flange and the floor. I can pour water directly into the drain
without any leaking problem. The problem is the water getting under
the flange and not into the drain.
I tried repairing this with plumber's putty and the fix lasted for
about 4 months. Eventually, the water washing over the putty lifted a
piece of it and the leak started up again today.
Is there some other way to repair this without having to go in from the
Thanks for any recommendations.
