Hayward W3S166T ProSeries® 16" Top-Mount w/ Valve

Hayward W3S166T ProSeries® 16" Top-Mount Sand Filter with Valve

The Hayward ProSeries® W3S166T is a 16-inch top-mount sand filter designed to deliver dependable filtration performance for above-ground and smaller residential pool systems. Built with a corrosion-proof polymeric tank, the ProSeries filter removes dirt, debris, and suspended particles as water passes through a bed of filter sand. This process helps maintain clean, clear pool water throughout the swimming season.

The filter includes Hayward’s VariFlo® multiport control valve, allowing simple operation for filtering, backwashing, rinsing, and winterizing. The internal diffuser and self-cleaning lateral system distribute water evenly across the sand bed to maximize filtration efficiency. :contentReference[oaicite:0]{index=0}
