After replacing the hot, cold and diverter valves, seats, and washers
without fixing the problem, I opened the wall behind my tub. I think
water may be coming from the overflow cover. I removed the two screws
that hold the cover, pryed out the old gasket and went behind the tub
to remove the vertical overflow pipe so I could clean rubber from the
angled fitting that the cover screws into. What is this fitting
I'm having trouble removing this fitting. There were two other screws
about 1/2" lower than the two that held on the cover. I removed them
but that didn't help. In fact, they don't seem to do anything. Can
someone tell me what are these screws for?
I also can't remove the overflow pipe from the rest of the drain
assembly. I'd appreciate hearing some tips.
The whole assembly is called a waste and overflow. The two lower
screws are just there to help the plumber to install the drain. I
suggest using a flash light and a mirror to explore where the leak is
coming from. There will be tell tale signs of old water, soap, skin
and other "water marks" to tell you where it's leaking. Do not try to
fix a leak that you cannot find.
I would take that rubber gasket to the store and get a new one and use
a little silicone and reinstall it. Make sure the brass "no-name"
fitting is in the right place. You will be able to tell.
It's very hard to get an old waste and overflow apart so if its not
leaking don't try to remove it. If you know it's the top gasket thats
leaking reinstall it and test it by poring water on it.

re: I think water may be coming from the overflow cover.
Others have mentioned how to remove the waste and overflow, but I have
a question - Why do you think the "water may be coming from the
overflow cover"? Do you see signs of leakage in this area?
I have a suggestion: Why not seal off the area with duct tape from
inside the tub. Dry the area completely and tape up around the
overflow cover and overlap some more tape up the wall, kind of like
flashing. See if this stops the leak before you start tearing apart
any more plumbing.
Keep this in mind: Very soon after I moved into my house, I was in
the backyard and saw water dripping just inside a basement window.
Actually it was more like running water, than dripping water. I ran
inside a found out that my wife was taking a shower. I told her to
turn it off and opened the access panel behind the plumbing.
Everything was dry around all the fixtures. Further investigation
showed that the grout on the walls was so porous that it was letting
water right through around the tiles. Once the wallboard behind the
tile got saturated, the water just ran down inside the wall until it
reached the basement. Once we opened the wall, we determined that
this had been going on for a while, but if enough time passed between
showers, the wallboard didn't reach it's saturation point, so we
didn't see the leak until we both took long showers one Saturday

No, I have not been able to determine the source of the leak. I think
it may be from the overflow plate and gasket for two reasons:
1) I have observed water leaking downstairs when my wife turns off the
diverter at the end of her shower. This would direct a stream of
water onto the overflow plate.
2) the old wedge-shaped gasket was not solid all the way around.
Today I replaced the old gasket and tightened the cover back on. I
placed a plastic tray with a paper towel in it which will catch any
water from the shower. I will monitor it for any sign of water. If
it is dry after 10 - 14 days, I will assume that I have solved this
problem and will close the sheet rock in the wall and ceiling.
Thank you for the advice. I really hope that I have found the source
of the leak but, of course, I will not be confident until a period of
time proves this repair to be effective or not.
re: If it is dry after 10 - 14 days, I will close the sheet rock in
If you removed that section of sheet rock to gain access to the
plumbing, why not spend the time you're waiting to put some trim
around the opening and cut a piece if luan to fit the hole? Having an
access panel to the plumbing is never a bad idea and if trimmed out
neatly will look just fine.
