    The problem is, and your recommendation was?

    The static pressure was 107 PSI. The neighborhood and the neighboring houses have about 60 PSI, since I had inspecting some of the neighboring houses. The subject house had a pressure reducing valve on the main water line and it appears someone opened it up. Two thankless water heaters that were independent of each other both issuing fault codes. Lawn sprinkler system had three zone valves that leaked. I suspect that and other things were related to the water pressure.

    I recommended they contact a licensed plumber to investigate the water pressure and pressure valve with the goal of getting the water pressure back to between 40 and 80 psi.

    121 PSI at the bottom of a neighborhood near a newer water tower in Allen. No apparent PRV there or at the neighbors. Back in the day, Allen had approximate pressure contour map on their public accessible engineering website. I checked back a few years later and could no longer locate that part of the map.
    On a related note, anyone have a good a cheap method to check pressure gauge calibration?

    Gene,

    With a pressure reducing valve already installed, call that out for a plumber to repair/replace if it cannot be adjusted to maintain pressure within the prescribed code limit of 80 psi - otherwise the potential for water system piping leaks will be high, as well as the potential for equipment/appliance damage (water heaters, dishwashers, clotheswashers, toilets, anything connected to the water supply system).

    I wouldn't recommend the low range you mentioned as they will have lower water delivery to shower heads and other use, just not exceed the maximum allowed by code for the system and its design.

    Jim,

    Keep a few pressure gauges handy for spares, and get one of those hose bibb manifolds with four hise outlets (at a Big Box store), use that for pressure readings (or just to compare gauges) and you can get a better 'apparent' pressure reading.

    When you use the word "calibrate", then means referencing to a known correct reading reference gauge ... which would be at a lab. Otherwise you would just be comparing one unknown gauge to another unknown gauge.

    With the four gauge manifold, you would be comparing four unknown gauges to each other, hoping that they all read nearly the same, while also hoping that 'nearly the same' reading is 'somewhat close to accurate'.

    The highest pegged my 160 psi gauge. I now use liquid filled gauges because the dampen the needle when opening the valve /faucet to check, We have extremely high pressure in my area. In 25 years I have replaced my regulator at least 6 times.
