Pump leaks water at the clamp band or housing seam

Safety: Turn off power and relieve pressure before loosening the clamp.

• Release clamp: Loosen and remove the Sta‑Rite pump clamp band or housing bolts. Separate the housing from the seal plate.
• Inspect o‑ring: Examine the large housing o‑ring for cracks, flattening, or chemical damage. Replace if any defects are found.
• Clean mating surfaces: Wipe the sealing surfaces on both the housing and seal plate to remove dirt or scale.
• Lubricate and reinstall: Lightly coat the new o‑ring with silicone pool lube, seat it properly, and reassemble the housing. Tighten the clamp evenly all around.
• Test for leaks: Restore power and run the pump, checking the seam for drips.
