Waterway 520-5147-6S ClearWater II Cartridge Filter System – 100 Sq Ft with Hi-Flo Pump (115V, 3' NEMA)

The Waterway 520-5147-6S ClearWater II is a complete above-ground pool cartridge filtration system that pairs a 100 sq ft cartridge filter with a Waterway Hi-Flo series pump on a one-piece equipment base. It’s designed to deliver strong circulation with simple installation using included hoses and fittings, making it a solid choice for new installs or replacing an older above-ground pump/filter package.

Key Features

• 100 sq ft cartridge filtration for clear water with longer run time between cleanings vs. smaller filters

• High-flow design with an advertised flow rate around 100 GPM (system dependent)
• Large 6" pump strainer basket/trap with clear lid for quick inspection and easy debris removal
• Complete connection package for typical above-ground hose plumbing
• One-piece mounting base helps keep equipment aligned and organized; base allows room for adding inline accessories (as needed)

Maintenance Tips

• Rinse the cartridge when filter pressure rises about 8–10 PSI above your clean starting pressure (or when flow drops).
• Deep clean the cartridge periodically using a cartridge cleaner to remove oils and fine debris; allow it to fully dry if using a degreasing soak.
• Empty the pump strainer basket often—restricted flow can reduce circulation and shorten pump life.
• Keep lid and union O-rings clean and lightly lubricated with silicone pool lube to prevent air leaks and drips.
• For freeze-prone areas, drain the pump and filter completely and remove hoses for winter storage.
