I have changed the flapper in the toilet tank to stop a trickle from
leaking into the bowl, however, the problem persists. I have installed a
new Corky Plus (red) flapper, which is supposed to be the best but this did
not solve the problem. The flush valve seems to be O.K., but I have no way,
short of microscopic inspection, to be sure. What do you guys do when
confronted with this problem? Should I change out the flush valve?
Thank you for your thoughtful consideration of this problem and the time you
take to answer it:)
