Shallow Well Pump Loses Prime and Low Pressure: Foot Valve and Leak Check

Shallow well sprinkler pump loses prime (needs hose priming) and delivers low pressure. Two fixes.

1. Install Foot Valve

At bottom of suction line. Holds water when pump off → no reprime needed. $15 part.

2. Check for Leaks/Restrictions

  • All valves fully open?
  • Suction line: no cracks, loose clamps, air leaks?
  • Discharge line: no kinks, clogged fittings?

No Pressure Tank Needed

For sprinkler-only, pressure tank not required. Foot valve + leak-free suction = reliable prime.

Start with foot valve. It's the missing component.
