I got around to sanitize my water tank yesterday, and turned on the pump, as I installed the water pressure regulator a couple of weeks ago.
I had left taps open for winter, and when I turned on the pump, water from galley sink and shower. Luckily I had some towels to wipe up!
I was pleased that the pump was so quiet, and no longer had water hammer. I could run the tap at low pressure, and no longer the pump surging. I have only configured the pump to recognize the hot water tank, as they default to tankless water heaters. I may do some more configuring.
I was going to originally install an accumulator tank, but happy that I bought this pressure controller.
On our 1995, difficult to get to wiring at back of pump, so removed the 4 screws holding it onto a mounting board.
Programming is via dip switches and a round dial. After I re-install the heater duct, I will use velcro to fasten to a surface.
