My measured flow at several faucets is now at 1.6 GPM and I have
noticed a reduced pressure/rate over the past year.

So, my questions to those who know - what/where can I look or do to

Thanks all.


Normal system pressure is usually in the range of 45-65 or so. You
can adjust it via the pressure switch that is typically located at the
bladder tank. Easy to find, just follow the wiring. Usually there
is a diagram under the cover that shows the adjustment screws and
process. Mine has two spring loaded screws. Adjusting one moves
both the cut-in and cut-out pressure. Moving the other only affects
one, think it's the cut-out, but not sure without looking. You
probably want about 20lbs diff between cut-in and out. You want the
bladder in the tank pressurized to 2lbs less than the cut-in
pressure. For safety, shut off the breaker before doing the adjusting
as their are live contacts in there.
