Hayward Vari-Flo Control Valve Assembly 2" for ProSeries Sand Filters W3S270T2 W3S310T2 | SP071621

The Hayward Vari-Flo Control Valve Assembly 2" (SP071621) is the OEM replacement multiport valve for Hayward ProSeries top-mount sand filters.

This six-position valve controls all primary filter functions — Filter, Backwash, Rinse, Recirculate, Waste, and Closed — through a single rotating handle. The 2" internal flow path delivers smooth, unrestricted water passage through each operating position. The flange clamp design allows 360° rotation of the valve body, giving flexibility when connecting to existing plumbing layouts.

Poolaroo Pro Tip

Before installing the replacement valve, inspect the valve body O-rings and the top-mount flange gasket. These seals are the most common source of leaks after a valve swap and are inexpensive to replace at the same time. Confirm the valve is in the "Filter" position before restarting the pump — starting under a closed or Waste position can create pressure spikes in the filter tank.
