Shallow Well: Leave the control valve open (in a shallow well
installation, the control valve always stays open).
Deep Well: The pressure should build rapidly to 50 PSI as the
pump primes.
Shallow Well: The pump should pump water in two or three
minutes.

control valve, and refill the pump and piping. You may have to
repeat this two or three times in order to get all the trapped air out
of the piping. On a deep well, don't forget to close the control
valve each time before you start the pump.
