Hi. We have three Sterling 1.6 GPF toilets. They're all about 10 years old.
One of them recently began to flush mysteriously on its own from time to time.
My husband just tried to repair it using a Fluidmaster Universal Complete toilet kit.
Unfortunately, we just heard it flush again on its own. This is not happening as often now, but something else is obviously amiss. BTW, the floor around the toilet is dry. Ideas? (There it goes again!)
