Sta-Rite Pump Prime But Low Pressure: Line Restriction or Worn Impeller

5-Year-Old Sta-Rite DS2 Pump Primes But Delivers Only a Trickle

Pump draws water, faucet at pump has flow but low pressure. Heads drip. Never had spring issue before.

Two Locations for Restriction

1. Suction side (before pump) – Clogged foot valve, screen, or line.
2. Discharge side (after pump) – Closed valve, clogged line, or worn impeller.

Test: Disconnect and Blow Out Lines

Disconnect pipes at pump. Force air or water through both directions to clear blockages.

If Lines Clear → Pump Issue

Impellers wear over 5 years. Remove and take to pump shop, or have tech inspect. Seal may also be bad.
