How to Fix / Troubleshooting
Safety: Turn off power and close valves before working on the pump.
- Assess crack location: Identify whether the crack is in the main volute, seal plate, or at a threaded port.
- Temporary repair: For small non‑structural cracks, a two‑part epoxy rated for pool use can provide a short‑term fix, but replacement is recommended.
- Replace housing: Order the correct Sta‑Rite pump housing or seal plate for your model. Transfer the motor, impeller, diffuser, and seals to the new housing.
- Winterize properly: In freezing climates, always remove drain plugs and blow out lines to prevent future freeze damage.
