I have one bathroom in my house. The bathroom is on the second floor. After the toilet has been flushed, the tank has been filled with replacement water, and the water is about to shut off, I hear a loud noise, like a hum, that fades away. The noise lasts about 10-15 seconds, I think. The same thing can happen with the shower after I adjust the hot and cold water temperature and switch the ouput from the faucet to the shower head. This was happening for a while several months ago, stopped, and now has started up again. What is the cause and how do I get rid of it?
Thanks for your help. Susan
