If the fluidmaster,itself is leaking, there is a rubber disk in the base of fluidmaster, replace disk. however, i can almost promise you the dripping you hear is from a bad flapper. replace with KORKY brand flapper. buy the basic black one, with no water saving gadgets on it.you will see cheaper black ones, but get the KORKY
