I recently had my dip tube replaced and now it seems the water heater "bangs" and is very loud throughout the pipes after hot water is used. Does anyone have any ideas or have had this occur? In addition, about how often should a gas water heater be replaced?

Thanks for the assistance.

Hello and welcome mhoverholt to the Do It Yourself Web Site and my Gas Appliances forum.

Banging noise is usually an indication of a buildup of sediment on the bottom of the tank. A flushing may correct this problem.

However, based on the fact that the diptube was replaced, may mean the tank is very old. Metal diptubes, to my best knowledge, haven't been used in many many moons. Plastic has replaced the metal tubes because it doesn't rust.

Flushing may only reduce the noise. The noise may return shortly afterwards. It's possible the internal damage has already been done. {Baked on rust in the bottom of the tank.} The tank just may need to be replaced.

You may also want to check the archives of this forum for other posting on the subject and complete flushing instructions. May also want or need to ask Plumber2000 in the plumbing forum.
