One of our toilets has a slight leak into the bowl. The bathroom is
attached to the bedroom so during the night I hear the tank fill
itself back up very quickly. I have swapped flappers with the
other toilet and even bought two new flappers. The first flapper
was a Korky but my plumber friend said it was for other model
toilets and I needed a Universal type Korky for the Universal -
Rundle toilet in question. The toilet still leaks despite the new
flapper. Do I need to replace the flush valve now? If so what do
you suggest? Any gotchas to be wary of?


Could also be tank to bowl connection. I had to replace the seal
once. I would also check the bolts of tank to bowl although leak
with corroded bolt is normally outside. If you replace the seal, I
would also replace the bolts.


Don't the bolts go outside of the bowl? There is no water on the floor
or at the nuts.


Yes, I was thinking that a broken bolt might not leak on floor but cause
a slight imbalance on the tank to bowl seal. It was many years ago that
I had to replace a tank to bowl seal and cannot recall the problem as it
presented itself but must have been a leak.

Cannot imagine a flapper not sealing if it fits the opening. I do have
a Toto that requires an OEM flapper but problem is in the flush itself.
