Sterling Toilet Drips Into Bowl W/New Flapper

[Molo]

Hi all,

Toilet bowl was dripping at rear of bowl. I cleaned the seat of the flapper opening and replaced it. Still dripping. I observed that it bowl drips even when the water level is below the flapper opening. Could this be the gasket below the overflow assembly or something different? It is a sterling toilet and I'm not sure of the flapper brand, but it performs the same way with the old and new flapper and as mentioned even with the water level below the flapper opening level.

Thanks for any replies

Sounds like you may need to take the tank off and tighten the big nut on the bottom. But, first, make sure it isn't leaking from the bolt holes that hold the tank to the bowl. The big gasket between the tank and the bowl could be bad, but that's fairly uncommon...usually it's just not tight or the nut is loose.

It could be a number of different things.

New flapper not installed properly.

Bowl refill tube inserted too far into the overflow tube.

Fill valve not set or working properly running over the top of the overflow.

just to name a few of the possibilities...

My top choices would be the flush valve gasket where the flush valve connects to the tank is all puckered up and preventing the flapper from seating correctly. this is very common on Kohler and Sterling toilets. You can trim the puckered part away with a single edge razor blade.

Another top choice of mine is you are using a flapper that has an adjustable float and it sets to light on the flush valve to get a good seat. I like to use the Korky # 16BP with the timer built into the flapper myself it closes harder IMHO.

Sounds like you need a new flush valve gasket. Since you've got the tank off to replace that, install a new tank to bowl kit as well . No sense in having to keep messing with it.

A standard 2" flapper does not cover on the Sterling.

The original part number is 84554 for the blue flapper

Now the question is, who carries these oversized flappers?
Like bigmtk says, it may be easier to just replace the entire flushvalve with a Fluidmaster replacement.
