I am getting very high pressure readings in my house at present. The
pressure is approx 120 lbs with nothing running in the house. When the hot
water tank turns on the water pressure is getting to 140 lbs and higher.
The problem was found because the hot water tank is discharging through the
pressure relief valve.
There is a pressure regulator installed right as the service enters the
house but it does not seem to be working. It has an adjuster on the top but
I don't know which way to go with it. From the only view I have (its behind
drywall) it does not have any markings or instructions.
Can anyone advise? Do I turn the screw into the regulator or away from it?
It has a bell shaped brass housing that sits above the water supply line.
The adjusting screw is on top. Does it need to be replaced?
Thanks - Tom
