Cracked Pump Housing from Freeze: Replace Wet End Only

Garage-mounted irrigation pump housing cracked from winter freeze. Motor runs but pump won't prime. Can the pump housing (wet end) be replaced without replacing the motor?

Yes—Replace the Pump Housing (Volute)

• Housings are sold separately by pump suppliers and irrigation distributors.
• Need: pump model number (on housing, not motor) and motor HP.
• May also need a new shaft seal (mechanical seal)—install carefully; they're fragile.

Common Spring Issue

Freeze-cracked housings are the #1 spring service call. Replacing the wet end costs 30–50% of a full pump replacement.
