Pentair WhisperFlo See-Thru Pump Lid 357151Z
This clear see-through lid is designed to replace the standard pump strainer cover on Pentair WhisperFlo pumps equipped with the 357151Z-style housing thread pattern.

- Helps identify debris buildup, air leaks, or flow issues at a glance.

When to Use / Replace
Use the clear see-through lid when you want easier visual access to the pump strainer/pre-filter chamber — especially useful during startup, heavy debris seasons (e.g., fall leaf drop), or whenever frequent basket checks are needed. Replace a cracked, cloudy, or leaking original lid to restore a tight seal and improve usability.
Installation & Care Tips
- Shut off the pump and relieve system pressure before removing the existing strainer lid.
- Inspect and lightly lubricate the O-ring/gasket before seating the new lid for a proper seal.
- Hand-tighten the pump lid clamp or ring evenly to avoid cracking the clear cover.
- Rinse the clear lid periodically to remove mineral buildup or clouding — avoid abrasive cleaners that can scratch the surface.
- Inspect the seal and O-ring annually — replace if hardened, cracked, or worn to maintain leak-free performance.
