Replace a damaged upper housing without replacing the rest of a serviceable Waterway Crystal Water cartridge filter. This genuine replacement lid is made for the 425 sq. ft. filter configuration and includes Crystal Water identification labels.
It’s a targeted repair for pool maintenance when the lower tank and other filter components are still in suitable condition. Use the labels to identify the intended filter configuration during future service.
- Specified fit: Designed for the Waterway Crystal Water 425 sq. ft. cartridge filter; other sizes and filter families use different lids.
- Upper-section replacement: Replaces the upper tank section while allowing serviceable parts of the assembly to remain in use.
- Labels included: Crystal Water cartridge filter labels help identify the equipment during maintenance.
- Package contents: Includes one lid and labels; cartridges, lower tank, clamp, main body O-ring, pressure gauge, and air-relief components are separate.
- Shipping details: Distributor-listed product weight is 21 lb; shipping dimensions are 23 × 21 × 28 inches.
Confirm your filter identification label and illustrated parts list before ordering. Waterway specifies different lids for its 325 and 525 sq. ft. cartridge filters; do not assume this lid fits those sizes, Crystal Water D.E. filters, or other Waterway filter families. The shipping dimensions are not installed measurements.
Have a qualified pool professional inspect the tank, clamp, sealing surfaces, O-ring, and air-relief components before replacement. Shut off the circulation system, prevent automatic startup, and fully release pressure before opening the filter. Follow Waterway’s instructions for positioning, clamp assembly, and air removal during startup; never operate the filter with damaged pressure-containing components.
