Internal leak in a toilet?
(about) daily between 3 AM - 5 AMish, if I have not fallen asleep 100%, I can usually hear my toilet making a water dripping sound on the inside. No water is leaking to the outside from the toilet. A Home Depot rep told me I only needed to replace the flapper. Not only did I replace the flapper, but I cleaned the dirt buildup from inside the flusher's bowl. The flapper only seemed to help for a few days, then I heard the same noise again. Another Home Depot rep suggested I replace toilet fill valve with a Quiet Fill toilet fill valve. Will this truly solve the problem, or just make the problem harder to hear? Thank you very much.
