Those water tanks must be mighty high and/or mighty high up a hill to

The water tanks are in parallel with each other and they are
definitely on
the same concrete platform as the pump house so their water height is all
that matters as they are directly behind the booster pump shed and on the
same concrete platform.

I'm guessing that they're 10 feet high ... they may be a bit taller
... but
not 15 feet.


If as you say, they are only approx. 10 feet, then that is only going to
create approx. 4.3 pounds of pressure to the inlet of the booster pump.
You have a duff gauge and/or a plugged line between the pressure switch
and the pump output.

Since they're paired and not stacked, the second adds volume but not
pressure, so it's only more like 2.3 psia.

On the latter, he's got a pressurized pressure tank just upstream a
couple feet that's producing the static pressure reading since the
system is still full...
