Gradually in the last several months, this sound gets louder and louder in the natural gas water heater if I shut off either / both hot and cold water anywhere inside the house, whether it is on a separate or mixed hot/cold water faucet or flush the toilet unless I shut it down so slow that it goes into a small stream / drip first.
I isolated the noise to the water heater, and have tried opening up the top valve to let out any possible air bubble, and it doesn't make any difference.
Has anyone seen this before? is it a sign of a dying water heater (made in 94, 50 gals for a 3 bedroom house), or something else?
