Description

The Pentair Quad D.E. Cartridge Style Filter 80 sq ft (SKU EC-188593) is engineered for residential in-ground pool systems where premium filtration, high water clarity, and simplified maintenance matter. With its 80 square-foot effective area and high flow capacity, this filter handles larger circulation demands while maintaining exceptional clarity. The robust fiberglass-reinforced polypropylene tank ensures long-term durability in outdoor, chemical-rich environments. The four-cartridge layout offers more surface area than traditional single-cartridge models and significantly reduces service frequency. For pool owners seeking elevated filtration performance with lower upkeep, this model stands out.

Pro Tip

Ensure your pump and plumbing match this filter’s capacity—aim to keep flow at or below ~160 GPM. Leave adequate vertical clearance for lid and cartridge access. Monitor the pressure gauge and whenever it rises ~10 psi above the clean-start number, plan for maintenance. Use genuine replacement cartridges and inspect O-rings and the clamp ring during each service cycle.

Installation Tips

High-level safety/compatibility notes only: Always shut off power to the pump and relieve system pressure before servicing or installing. Mount the filter on a level pad rated for the tank plus full water/media load. Confirm plumbing ports match the filter’s 2-inch connection. Lubricate the lid O-ring, ensure the clamp ring is properly seated and tight, and verify the drain plug and air relief valve are functioning before returning the system to service.
