After fifteen minutes, Kohler toilet water tank keeps overflowing.
I have a 1.6 liter per flush Kohler toilet - about five years old. This is
my problem. After I flush, all goes well. The water tank fills up and stops filling as it's supposed too. This about fifteen minutes later, however, the water tank slightly overfills and thus begins to pour into the overfull hole. This is very gradual. I put a new flapper on it and it is not leaking. Seems like the float level is OK as well because it stops short of overflow when toilet is initially flushed. What is causing the slow overfilling of the water tank and how can I fix it? Any assistance is greatly appreciated. Frank |

IIRC, Kohler used the Fluid Master ballcock: http://www.fluidmaster.com/usa.html If it looks like that, replace the seal. Jim |

If it is Fluidmaster, you can turn off the water, twist the top half off and
turn on the water to try to clean it out. They also sell some replacemnet parts if you don't want to replace the whole thing. "Speedy Jim" wrote in message ...

Frank you might also want to check the float ball to make sure its still floating.. on one of my old toilets the ball was full of water and heavy as hell and would sink down and not turn the water off as it would not float all the way to the top of the water.... |
