Hi..
   this is from a 1999 entry to a thread about electric pumps.  To see the
whole thread  go to

 Check valves:  These permit water flow from the pump and prevent backflow.
I used a modified 1/2 inch pvc valve designed for home plumbing systems. I
decreased the opening pressure (200 psi) by unscrewing the spring cap,
cutting the spring roughly in half, bending the cut tip to fit the cap,
then putting it all back together.  This cut the opening pressure
acceptably, so that the valve did not appreciably slow the pump's outflow.
