Waterway 520-5337-6S Carefree 19″ Sand Filter System with 1.5 HP Hi-Flo II Pump
Part Number: 520-5337-6S
Description
A complete pump and filter system designed for above-ground and some smaller in-ground pools, combining a 19-inch diameter sand filter tank with a 1.5 HP Hi-Flo II single-speed pump. This system is engineered to deliver large sand-capacity filtration and high flow rate for efficient turnover and water clarity.
Compatibility & Fitment
- Designed for above-ground pool installations, or in-ground pools where plumbing and flow match this size system.
- Filter tank is 19″ diameter compatible with standard sand media (typically #20 silica sand) and includes 7-position top mount multiport valve.
- Pump is configured with a NEMA-type 3-ft power cord (as denoted by the “-6S” suffix).
Features & Specifications
- 19″ filter provides expanded sand bed for increased filtering capacity and extended run time between cleanings.
- Hi-Flo II 1.5 HP pump offers higher flow rate (~45 GPM) for improved filtration and circulation in larger pool volumes.
- Large 6″ diameter pump strainer lid for ease of maintenance and visual inspection.
- Filter body constructed of roto-molded polymer for corrosion resistance and durability in pool environments.
- Includes hoses, union adapters, hose clamps and base for straightforward installation.
Installation Notes
Ensure the pool plumbing and breaker are sized appropriately for a 1.5 HP pump. Mount the filter base on a stable, level pad. Install the filter tank and multiport valve, connect the pump, and fill with #20 silica sand to manufacturer height. Prime the pump, then operate the system and monitor pressure gauge—clean sand once pressure rises about 7–10 psi over initial reading.
Maintenance Tip
Inspect the pressure gauge weekly and backwash the filter when pressure rises roughly 50% above start-up level. Replace the sand every 3–5 years or sooner if water clarity declines or run-time increases. Lubricate O-rings annually and check for leaks at unions and pump lid.
