In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
On our natural gas boiler, there are 2 gas valves (2 stage burner). They are made by Johnson controls. The valves are each activated/opened by a solenoid in the valve.
Since the valve train is hooked up directly to the gas line which is steel and runs under our kitchen and family room, whenever the valve(s) open, there is a distinct metal banging/clanging sound that is transmitted through the pipe and into our living space. It sounds like someone is giving a metal pipe a whack with a wrench (for a split second).
That does not happen when the valves close/shut off. I tried putting some type of dampening material (rubber) between the pipe and the hangers, but that did not work.
Has anyone else had this kind of problem, and is there any way to alleviate the noise? The main valve was even replaced, but the sound from the new one is the same as before. Thanks.
