I have a toilet that is running, probably once every ten to fifteen minutes. I hear a quiet dripping sound within the tank. I understand that the most common problem associated with these events is a flapper that needs cleaning or replacement. Mine is pretty new and looks clean. I've now just cleaned it again. I've shut off the water to the tank. After I flushed, only a small amount of water remains at the base of the tank, and I'm still hear the dripping sound.
I'm not sure what the piece is called, but should I perhaps be caulking around the piece that the flapper inserts into? Or maybe I'll just replace the flapper again?
I appreciate any help anyone can offer,
