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?


I received a suggestion to shut off the water and let all the water
out except for what remains, then put food coloring in the tank.
That trick confirmed water was leaking past the seal to tank of the
flush valve when the colored water showed up in the toilet. I
bought a new Fluidmaster Universal flush valve and installed that.
It comes with its own flapper.

The problem remains. It still leaks exactly the same as before. It
looks like it's leaking through/below the front of the the flush
valve seal. I also noticed bubbles clinging to the front of the
valve. I have taken some pictures which you can view below. I
didn't see any cracks in the tank or anything else. Any
suggestions welcome.

Did you also unbolt the tank from the bowl and replace the separate
tank to bowl gasket ??

Like these:

I took the tank off the bowl and checked the tank to bowl gasket, bolts
and washers. They were all fine and supple. There is no leak out of
the tank onto the floor, only into the bowl. How would the tank to
bowl gasket cause a leak into the bowl? The water has to get past the
flush valve to tank seal.

It's probably the flapper. I will post a link to help you determine the part
you need. Sometimes this "universal" part just doesn't do the job.
I know I am coming in late but trying to help...
Let us know when you achieve man over machine.
