DH and a friend replaced all the parts in our two toilets today due to
slow leaks (both toilets had seals/gaskets/washers sooooo old that it
was amazing we didn't have slow leaks any sooner).
Toilet #1 is fine. Toilet #2 is leaking from the tank (in the big
gasket, screw mount area - we cannot tell for sure, even though we have
monitored it very closely). While our friend thought the leak was
coming through one of the screw holes, DH and I have think it's the big
gasket seal in the center of the toilet (that seals the hole from
toilet to bowl). The screw holes were replaced with the double rubber
seals on the inside and the washers on the outside (as I have read in
FAQ do-it-yourself toilet repair). So....everything looks good
We considered the possibility that maybe this gasket was not
large/puffy enough for the hole, but it seemed to work fine for its
twin in the other bathroom. Perhaps this gasket is defective?
We tried mounting and re-mounting the tank and each time we got
different results (always a leak, but of varying degrees - from a very,
very slow sweat, to a fast, fast drip - and then everything in
between). Our friend attempted tightening the screws/bolts some more,
but that had no affect. He didn't want to screw them too fit for fear
of the tank cracking.
I have two theories:
1. The new gasket seal that goes from the outside of the tank to the
bowl hole is not large or puffy enough - OR - is defective somehow
(although it looks fine).
2. The tank has a hairline crack that we cannot see. I think we've
disproved this theory due to different results with each mounting of
the tank, but - I really don't know.
DH says, "Let's just call a plumber and be done with it". I am
hovering around our drained tank at the moment feeling like I've just
been defeated by it! I wanna fix that sucker myself!
Any ideas of something we should try differently, or should we just do
what DH says and pay for the expert to fix up or mess?
