Hello everyone,

I bought a condo in a building that was built in the 1920s within the
past year and the head of the condo association brought a leak in the
basement to our attention a few months ago. Considering the extent of
the damage that was already there (the whole basement ceiling is
plastered over EXCEPT where this spot is--it's got moldy boards
hammered up over it and all the beams are splashed with rust), I
figured it couldn't actually be from my apartment since certainly the
previous home owner or someone on the association would've said
something!

Lo and behold, of course, it IS from my apartment. Every time I take
a shower, it leaks down into the basement. The head of the
association keeps insisting it's the caulking on the tub, but it looks
absolutely fine to me. I can't find any cracks or holes in anything
that would allow that amount of water to escape. And it only ever
happens when someone is IN the shower. if you leave the shower
running, no water leaks downstairs.

Could it possibly be the overflow on the tub? I need to call a
plumber but I'd like some idea of what it could be before I'm charged
an arm and a leg to replace a bunch of stuff because I'm a new,
clueless homeowner.

Thanks for any help anyone can provide!

I had a similar leak that turned out to be around the tub spout.
Shower water would run down the wall and behind the spout.
I caulked the top 2/3 of the gap between the spout and the wall
and the problem went away.

Yes, it *can* be from the overflow. This is a fairly common
problem. Showering produces a heavy flow of water right over
the plate.

There is a rubber gasket behind the tub which is supposed
to seal everything, but they often are out of place or
deteriorated.

You can replace the gasket from inside the tub by snaking
it thru the opening. Some sealant on the new gasket won't hurt either.

The assembly looks something like:

As suggested, don't overlook the penetration for the tub spout either.

I had a bathtub that would only leak when someone was in it. You
could fill it with water and leave it and it wouldn't leak until
someone got in.

Turned out that the drain basket nut wasn't tight enough and the added
weight of a person would flex the tub enough to open a small path for
a leak around the drain.

Have someone take a shower while you watch from below...

HTH,

Paul

imho:

I saw on TV, where the face plates from the fauciets and shower
handles had a foam gasket. The show guide said they quickly degrade,
and should be replaced with plumbers puddy. It was recommended that
every several years to check and replace as needed.

Do you think you getting watter running down the wall and going
behinde these faceplaces?
