STA-Rite Pump Loses Prime - Troubleshooting Guide

Pump Runs But Moves No Water

A STA-Rite SLE-1 pump had a puddle underneath after use. Next day, motor runs continuously at 30 psi but pumps no water.

Diagnosis: Loss of Prime

The puddle suggests a suction-side leak. Without prime, the pump spins air, pressure switch never satisfies, motor runs non-stop.

Steps to Fix

1. Refill pump casing completely with water (prime).
2. Run briefly, then shut off.
3. Inspect all suction fittings, pipe, and check valve for leaks.
4. Repair any found leaks; re-prime and test.

If no leaks found, check foot valve in lake/well for debris or failure.
