My house has a pressure regulating valve and a expansion tank above the water heater. House was built in 2000.
I'm trying to lower my water pressure which currently reads 82 psi when idle.
When I run the kitchen faucet it falls to 50 psi and when I shut it off it then slowly climbs (I hear a faint water flowing sound even though nothing is turned on), takes about 3 min to get to 60 psi, 6 min to get to 70 psi, and 9 min to get to 80 psi again and the water flow sound stops.
If I do the same thing with the kitchen faucet to get fall to 50 psi, and go shut off the cold water intake right before the expansion tank at the water heater, the pressure would immediately jump to 80 psi.
Is this normal?? Any idea what has failed???
