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.

- 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

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.
