Superior filtration from the inside out.

Cost-effective and convenient, Hayward Pro Series Pool Sand Filters offer the ideal combination of energy efficiency and durability. Enjoy outstanding water clarify with the value promise that Hayward delivers on every time.

With the help of an integral top diffuser, unfiltered swimming pool water is distributed evenly throughout the entire sand bed in a cascading, umbrella-like pattern. This allows the greatest filtration possible from every square inch of sand. Then the self-cleaning under drain assembly, with its 360 slotted laterals, provides a fast, balanced flow of clear water back to the pool while allowing for more thorough back washing. Best of all, the Hayward Pro Series full-flow technology reduces your energy costs because the pool sand filter operates for shorter periods.

A seven-position valve puts you in control. The patented, multiport control valve developed by Hayward was designed with seven swimming pool filter positions: filter, backwash, rinse, waste, closed, recirculate, and winter. An easy-to-use lever-action handle lets you quickly dial any function.

Built for long-lasting convenience! You can easily access your Hayward Pro Series pool sand filter assembly for simple servicing via the unique folding ball joint in the laterals. A corrosion-proof housing protects the filter system from severe weather for years to come.

Tips for Using the Hayward Pro Series

  • No fancy tools or special skills required for installation.
  • For winter pool closing, drain tank completely by unscrewing the cap at the base of the tank.
  • For best results, run the pool filter long enough each day for at least one full pull water turnover.
  • Maintain all pool chemicals, as algae and bacteria growth can affect how the pool sand filter functions.
