My house has toilets with a common Mansfield mechanism. There's a white plastic tower that is lifted by a lever from the handle, that dumps water into the bowl, then the moving part of the tower falls back down to the circular seal and the flow stops.
I've had (many, over the years) seals fail. Replacement is easy. But now I've got a toilet that acts like the seal has failed, in that water very slowly runs into the bowl, and if the water supply is shut off, this drains the tank down to the level of the seal (technically to the level of the lip of the thing the seal goes around). But replacing the seal doesn't fix it. I looked at the bottom of the moving part of the tower. Clearly if it were cracked or there was a chip in its lip, that could cause the same thing. But it looks fine.
Any idea what is going on? What should my next move be? I can post photos if needed.
