Hayward W3S244T ProSeries 24-Inch Top-Mount Sand Pool Filter

The Hayward W3S244T ProSeries is a 24-inch top-mount sand pool filter for shoppers who want a durable, serviceable filter tank rather than a compact cartridge setup. It uses a sand media bed, a top-mounted VariFlo valve, and a corrosion-proof polymeric tank to support routine pool filtration and backwashing.

Best For

It is best for pool owners replacing or upgrading a larger residential sand filter, especially those who want a 24-inch tank, a 1.5-inch top-mount valve, and a design that is familiar to many pool service professionals.

What works

  • 24-inch sand filter tank with 3.14 sq. ft. effective filtration area
  • Includes a 1.5-inch top-mount VariFlo valve for common filter functions
  • Corrosion-proof polymeric tank is built for outdoor pool equipment pads
  • Integral top diffuser helps distribute water over the sand bed
  • Large sand and water drain supports servicing and winterizing
  • Uses self-cleaning laterals for balanced flow and backwashing

Tradeoffs

  • Filter-only purchase, so pump and plumbing compatibility must be checked

Why We Like It

The strongest appeal of the W3S244T is its combination of a proven sand-filter format and practical service features. Hayward lists a 3.14 sq. ft. filtration area, 62 GPM design flow rate, 300 lb sand capacity, 50 PSI maximum working pressure, and a 1.5-inch VariFlo valve included with this open-line model. We also like that the tank is molded from corrosion-proof polymeric material and uses an integral top diffuser plus self-cleaning laterals to spread water across the sand bed and support balanced backwashing. For buyers who are already set up for sand filtration, it is a straightforward, familiar upgrade path.

What Buyers Notice

Public buyer feedback commonly highlights good water clarity, solid value, and easier-than-expected installation when the filter is matched correctly to the pool system. The main setup reminder is to inspect the internal laterals, add sand carefully, and confirm plumbing size before starting the system.

Who Should Buy It

Buy this if you are replacing a similar 24-inch sand filter, upgrading from a smaller unit, or building a system where a 1.5-inch top-mount sand filter fits the pump, plumbing, and pool size. It is especially sensible for buyers who are comfortable with basic pool equipment setup or have a pool professional handling installation.

Detailed Review

The Hayward W3S244T ProSeries is a 24-inch top-mount sand filter designed for buyers who prefer the simple maintenance routine of sand filtration. Instead of disposable cartridges, it uses a bed of pool filter sand to trap debris as water passes through the tank.

The official specifications make it a serious step up from small above-ground filter units: 3.14 sq. ft. effective filtration area, 62 GPM design flow rate, 300 lb sand capacity, and a 50 PSI maximum working pressure. The listed dimensions are 42 inches high by 24.5 inches wide and long, so it is important to measure the equipment pad before buying.

Everyday operation is centered on the top-mounted VariFlo valve. This lets the user switch between common filter functions such as filtering, backwashing, rinsing, and other service positions depending on the installed valve labeling. The flange clamp design also allows valve rotation, which can make plumbing alignment easier during installation.

Inside the tank, an integral top diffuser helps spread incoming water over the sand bed, while the self-cleaning lateral assembly supports balanced flow and backwashing. These are practical design details because even water distribution helps the filter media work more consistently.

For maintenance, the large sand and water drain is useful for servicing or winterizing. Buyers should remember that sand is not a small accessory here: the W3S244T requires 300 lb of filter sand, so delivery planning and careful filling matter.

Overall, this is a strong choice for pool owners who want a known Hayward sand filter model with service-friendly features and enough capacity for many residential in-ground pool setups. It is less suited to shoppers who want an all-in-one pump system or a low-lift installation with minimal plumbing work.
