Hi,
My house is two story, slab with copper piping. Every fixture/appliance in the house makes some noise when it shuts off, even sink faucets but solenoid based devices make a really loud bang. I often even hear noise when there is a constant low volume flow - sounds like a coffee maker percolating coming from the water heater area (water heater not heating at the time). Kind of like a click-click-click noise, very regular.
When I hold on to the cold water supply to the water heater I can feel the shock on the line when something turns off. Often it will echo several times over 2 secs or so. The sound seems to come from the water heater area and propagates through the home more acoustically than from a shock to the framing so I don't think it's a loose pipe.
I carefully checked my main water pressure and it's very stable at 50 psi.
All piping for my sprinkler system is outside of the house.
So, I installed a Oatey 1/2" arrestor at the water heater cold water supply. It didn't make any difference!
I have a toliet that is 10' from the water heater and when it shuts off I can clearly hear the noise (after installing supressor). You would think being so close it would at least help with that fixture.
Any ideas what's going on here?
Thanks
P.S. I asked about this on another forum and the "experts" there assumed I had a pressure regulator somewhere in the system which is causing a pressure rise in the system due to the water heater. I looked for any access panels in my garage and did not see any. I do not have an expansion tank for the water heater.
