Thank you very much, the_man.
I erred --- my Q should say: PWs that output 2000-3800 *psi*!
But you caught that.
Q is, I'd have to look up a particular model's specs to know for sure ...
A PW might advertise, say, a 2.7 gpm capability.
I assume that's referring to usage/output, the same as intake requirement (that is, if my well pump and pressure tank are both capable of at least that 2.7 gpm output, no worries about burning out/busting either?!)?
yea you should be fine. I've never seen a 3 gpm well pump assuming the water table is high enough, normally you'll have at least 10 gpm. 2.7 gpm isn't even a fully open garden hose (half a 5 gallon bucket in one min.)
