Pump runs but there is water leaking from the join between the pump housing and the volute cover.

Safety: Turn off power and relieve pressure before loosening housing bolts or clamps.

• Tighten fasteners: Evenly tighten the Onga pump housing bolts or clamp band to ensure uniform compression.
• Inspect O-ring: Open the housing and check the large O-ring or gasket. Clean, lubricate, or replace if damaged.
• Check for warping: Inspect mating surfaces for warping or cracks. Replace the housing or volute cover if necessary.

Reassemble carefully and test for leaks. A dry housing is important to prevent motor corrosion.
