Common Signs You Need This / Use This When

Product Specifications

Compatibility / Fitment Notes

Use SW-22-310 where the existing Hayward Super II pump calls for SPX3100D. Confirm the pump model and original lid part number before ordering. Do not assume compatibility with every Hayward pump simply because the lid appears similar.

Installation / Use Notes

Shut the pool pump off before servicing the strainer lid. Remove the existing lid and O-ring, clean the sealing surfaces, install the replacement components in the proper position, and make sure the lid is correctly seated before restarting the pump. Follow the pump manufacturer's service instructions.

Buy with Confidence
