Installation & Compatibility Notes

Before installation, shut off the pump and isolate power. Relieve system pressure and drain the pump if required. Remove the existing wet end assembly (housing, lid, basket, seal plate etc). Clean the seal surfaces and inspect internal motor shaft/bearings. Install the new volute/pot housing and seal plate per the kit instructions, replace O-rings, reassemble the basket and lid, reconnect pump to plumbing ensuring proper alignment and torque. After startup, monitor for leaks and verify normal pressure and flow performance.

Maintenance Tips

• Inspect the new wet end after initial run-in for leaks or unusual vibration.
• Periodically check the basket, drain plugs and locking clamp for tightness and debris build-up.
• If you experience rising pump pressure or flow decline, inspect the volute and seal plate as part of your service checks.
• Store spare O-rings and related components as part of your service vehicle inventory, since this kit addresses a common wet-end failure point.
