New Irrigation Pump Loses Prime: Check Valve and Suction Line Leaks

Pump Primes Briefly Then Runs Dry; No Pump Relay Installed

This is a priming problem. A check valve on the suction line is required to hold prime.

• Install a check valve (foot valve) at the water source.
• Ensure the intake screen is clear of debris.
• Check for air leaks in the suction pipe (tighten all fittings).

Once prime is held, the pump will deliver continuous flow.
