Hello all. I posted this in the main Plumbing Forum as well, yet thought this forum might be more relevant. I’m brand new to the forums, as well as being a first-time homeowner (who has a LOT to learn!). I moved into a home around a year ago that has a 810’ well. About 6-months ago, I started to notice loud “banging” in the utility room where the pressure tank and water treatment systems are.
When the pressure tank gauge drops to 40psi, and the well pump is energized, the initial loud “bang” occurs. Then, when the pressure tank gauge rises to 60psi, and the well pump is de-energized, a series of loud “bangs” occur. I’ve had 6 plumbing professionals come over to take a look at this, and no one seems to have an answer as to what is causing this issue. One Plumber put on a new check valve and water hammer arrestor on the “well side” of the pressure tank. That didn’t seem to make much of a difference. The most recent Plumber thought that the new check valve installed wasn’t necessary, and perhaps was creating the water hammer/“bangs”. He took the check valve off and just put piping where it was, yet that didn’t alleviate the banging either.
A couple have had theories that this banging may be caused from inside the well, and perhaps I need a new pump, check valves, and pipes. Although, my water pressure has not changed (it’s good) and the pump averages a flow rate of 10.3gpm (which I understand to be quite decent for well pumps in my area). I was just hoping you all may have some thoughts as to what may be creating these “bangs” (if indeed they are “water hammers?). Thank you very much for any insight you all may have!
