Benefits

The Pentair 350171Z kit helps restore proper sealing and lid security on compatible EQ-Series commercial pump strainers. A damaged or worn strainer lid clamp can cause air leaks, priming problems, water leaks, reduced pump performance, or unsafe equipment operation.

Replacing worn clamp and gasket components helps the pump maintain a strong seal at the strainer lid, which is especially important in high-flow commercial pool systems. This can improve service reliability, reduce downtime, and help prevent unnecessary replacement of larger pump components.

For pool professionals, this kit is a practical OEM repair solution for maintaining Pentair EQ-Series commercial pump systems.

Installation Notes

Turn off power to the pump and relieve all system pressure before servicing the strainer lid assembly. Never remove or loosen the lid clamp while the pump is running or while the system is under pressure.

Inspect the clear lid, sealing surface, gasket groove, lock ring, clamp cam, ramp, strainer body, and surrounding plumbing before installing the replacement parts. Replace any cracked, warped, or damaged lid components before restarting the pump.
