water heater buzzing when running water
My suburban water heater is making a buzzing sound when we run the hot water. Anyone have any ideas?

Definitely the check valve. It either has debris in it or has come apart inetrnally. If it is easily accessible it would be easy to replace. If hard to get to then may not be worth the effort. Mine has been doing it for 3 years now. It is not easy to get to.
