I have a Kohler toilet, installed in 2000. Recently it has been making a flushing ( hissing) sound from the tank. The plumber has been here 4 times. He replaced the flapper, vacuumed the tank, did the dye test, changed the float, and finally replaced every component in the tank. It is still making the noise. Any suggestions?
