I'm merely repeating what the plumber told me regarding the new tanks
versus the old tanks.

Anyway, I've had the new Watts pressure gauge, that I just bought,
connected to my hose faucet for an hour 11:05 pm to 12:05 am. The
pressure did touch as high as 98 or 99, according to the red "memory"
needle, but it never got over 100. Also, the pressure did not appear
to staying up at those levels (when I would go out periodically and
observe the meter for a few minutes at a time.) It seemed that
pressure went above 90 it did not stay there very long. There were
times I would see the needle stay around the 90 level, but it would
hover around the 80 level just as frequently if not moreso than
hovering around 90. I'm going to leave the pressure gauge connected
overnight to see how high the red "memory" needle reaches.


I don't think it matters how long the needle stays there. I'd be
putting in a pressure reducer. High pressure is going to be hard on a
lot of things, such as toilet valves, etc. Coming home or getting up
to find a wet floor is not pleasant.
