Running Toilet - Flapper Missing Seal?
I have a Jacuzzi Perfecta toilet in my kids bathroom less than a year old which has worked perfectly until yesterday; the water now constantly runs. I checked the obvious and all the mechanics are functional. Tracing the leak implicates the TOP of the flapper, not at the "normal" seam where the flapper meats the flange. Also, I pushed down on the flapper to force a better seal, it leaks exactly the same.
In fact, it appears the four holes on flapper itself are where the water is draining out. I removed it and here are pics:
Am I suddenly missing an entire gasket/seal on the flapper bottom that should be covering those holes? It seems completely obvious there should NOT be "drain" holes in the flapper itself. DUH. If I place my fingers gently blocking the holes, it stops leaking. Perhaps the holes are intentional to signal seal degradation to the user? If it doesn't text or tweet, nary a signal will reach my kids over the blaring music in their IPod's head phones.
Note this is an all-plastic flapper sealing against a plastic flange -- it MUST be missing a rubber gasket, right? Unless toilet technology has progressed that cheapo toilets containing cheapo plastic parts are now finely "machined" to create water-tight perfect seals. The only visible gaskets are between the tank innards and the tank itself (e.g. flange --> tank connection).
Question: If the seal came off, are the odds it made a "dirty" getaway along with the contents of someone's "business"? There is no sign of it -- it never calls .... it doesn't write.
