I put a pressure valve on my garden hose connection on the outside of my house. It reads 120 psi during the day, it peaked at 190 over night. I tried it again last night...same numbers.
The house is a 1959 colonial. It has a 1" line coming into a 3/4 water valve followed by a 3/4" line to the hot water tank and 3/4" water line to the water manifolds. From the manifolds, 1/2" copper everywhere else in the house.
I thought that the pressure was high because I kept blowing garden hoses. I always turned the water off when not in use. All I have to do is wash the car in the sun 1 time...then I'm off to Home Depot.
The pressure relief valve on the hot water tank is rated for 150 psi. However, there have been times when I see some water on the floor around the hot water tank. Not a lot, but enough that its getting past the valve. (The tank is only 4 years old. 40 gallon.)
Not sure what my options are. I also don't know how serious my pressure issue is. I know that 120 to 190 psi MUST be high water pressure because the pressure gauge I have to test it only goes up to 200.
Thanks in advance for any help or suggestions...
