Question about Amtrol ST-12-C THERM-X-TROL ASME Expansion Tank, 5 Gallon
I have a substantial humming in my copper piped home. I have shut off all toilets to isolate them. The hum occurs only when the water pressure is trying to rise back to line pressure after using ANY main floor valves. There is an Amtrol ST-5 inline to the water heater. Since this is a valve I was wondering if it could produce a hum in the piping system.
From your description, I am guessing you are on a deep well with this answer. I think you have an issue with the well pump. To isolate it do this...........
Turn the main supply valve off to the house. Your well tank should have a hose bib on the well tee. Hook a hose up to that and run it outside. Open the valve to the hose until you heard the pressure click on which activates the pump. After the click close the valve and listen for the hum. If it still hums it is the Well and not the piping in your home.
Please rate this response after testing and Good Luck, Phil
