in THE MAIN WALL
The water pressure in my home is 100psi. Is this excessive? Is it necessary or desirable to reduce it? Should the expansion tank I have connected to the cold water heater be adjusted to match the street pressure?

    pressure

    Paul -- was that the pressue reading at dinnertime, breakfasttime' or midnite? Looks a little high like to see a midday pressure of not over 80 PSI. So add a pressure reducing station and then adjust you exp. tank to match.Best Wishes J.Lockard

    pressure

    I measured the pressure at mid day. Then I called the local water company to verify my reading. They said the pressure could very between 100 and 125 psi

    Paul,

    industry standard keeps working pressure under 80 psi. You should have a pressure reducer installed on your system.

    Most domestic PRV's (Watts U5B, for example) come set at 55psi which is more than adaquate for houshold use.

    After installation you can match your expansion tank to the PRV setting.
