- Inspect O-Rings: Check all O-rings for wear, cracks, or damage. Replace if necessary to maintain a watertight seal. Applying a small amount of O-ring lubricant can help with sealing and reassembly.
- Reassemble: Carefully reassemble the pump, ensuring all parts fit correctly and O-rings are properly seated.
- Test: Place the pump back into the water and reconnect power to test its operation.
