Hello,
I have since changed the sprinkler zone valve in this pic and a new ball valve.
The problem is this pump has never held prime so I changed the intake brass check valve, ball valve, Sprinkler zone.
Now, if I close the ball valve then shutdown the pump it will hold prime for months. If I open the ball valve it will lose prime overnight. Does a sprinkler pump lose prime on the discharge side?
Would putting a check valve on the discharge side on the vertical of the pvc work? I guess I can only do it and see if it works.
Thanks,
Noel
