Possible Causes
Damaged housing O-ring, Cracked pump housing, Worn mechanical shaft seal, Loose housing bolts
How to Fix / Troubleshooting
Safety First: Unplug the pump and relieve system pressure by opening the filter housing before disassembly.
- Identify leak source: Dry the pump and run briefly to see exactly where water appears (housing seam, lid, or motor junction).
- Service lid and housing O-rings: Remove the lid and housing clamp or screws. Inspect O-rings for cracks or flattening. Replace with Summer Waves-compatible O-rings and lubricate with silicone.
- Check for cracks: Inspect the plastic housing for visible cracks. Replace the housing if damaged.
- Shaft seal: If water is leaking between the motor and pump housing, the mechanical shaft seal is likely worn. This typically requires replacing the seal kit or the entire pump wet end assembly.
