Title: Flapper valve fails in 2 years--replacements don't work
Review: Much of what I am saying has been documented in other comments--I am just adding bulk here. I have replaced a number of toilet guts in my house, my rental houses, and for my handyman customers. It still takes me 1 1/2 hours to remove the tank, then replace the parts and tank. That makes it particularly galling when, two years later, the flapper quits. I have never found a flapper replacement that will work, including a Fluidmaster replacement. In some cases, it could be the tank gasket is giving out, but that doesn't matter much. If you have to take the tank off you might as well rebuild the toilet. Obviously unacceptable. I went here looking for someone who had the same problem that found an alternative make. Korky is the only recommendation I saw.
Is the review positive or negative?
