Background info:
Water dept says they deliver 80 psi. Turning off all cold water faucets quickly, fluidmaster 400 toilet valve and washing machine cause hammer. I
have a Bosch on demand gas tank-less water heater. Water meter located in utility room, mount vertically 2' above concrete floor with 60 year
old shutoff valve below it. Shutoff valve does not fully stop water flow, while closed fine stream of water coming out. Water department shutoff
4 feet below ground somewhere in the yard.
The Plan:
Close in house shutoff valve ( fine stream of water still flows in closed position) best I can and install threaded 1" ball valve on out flow threaded
nipple to become working shutoff valve. There is a floor drain 2 feet away. From this point continue on to install PRV. Since I have tank-less
water heater would I still need an expansion tank? Would this stop the water hammer?
Would lowering the water pressure affect the operation of the tank-less WH?
Thanks in advance. All comments welcome.
