If your tank runs every once in a while, but seem to be getting more often or runs constantly- 1. check flapper & chain 2. If ok you probably need to replace the flow valve Hope this solves it

Tools. Look at flapper- that may be the only replacement. If not, then proceed on to the flow valve. I had to replace tank seal also due to water leaking outside tank.

Getting the old seal out was no picnic. It would not release from old screws. Now place new seal and screws. Secure joining new center plastic nut and the PVC tower inside. Place tank back on seat.
