Waterway Tank Lid with Lock Ring, Pro Clean Plus 125/150 sq ft

The Waterway 550-0621 is the replacement tank lid for the Pro Clean Plus cartridge filters in the 125 and 150 sq ft sizes, 2015 series. It comes as a complete assembly: the lid, the locking ring that holds it to the tank and a pressure gauge already mounted. The assembly stands 15 in. tall.

Cross reference

The same lid is sold under Leslies and Jacuzzi part number 677828, so if that is the number on your filter or in your manual, this is the matching Waterway part.

Before you order

The tank o-ring is not included. Since the lid has to come off to fit the new one anyway, inspect the o-ring and replace it if it is flat, cracked or stretched. Confirm your filter is the 125 or 150 sq ft Pro Clean Plus; other Waterway filters use different lids.
