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?

Check valves buzz at low flow, and I agree it is the check valve.
What kind of bypass do you have
Single valve, requires a check valve on the outlet. OR you can replace the check valve with a quarter turn
2 and 3 valve systems do NOT need check valves
Some companies put check valves on both the outlet and the inlet, why, I will never understand, but they do it.
