Hayward W3S244T2 ProSeries 24" Pool Sand Filter with 2" Top Mount VariFlo Valve
Clean water, day after day.
The Hayward W3S244T2 ProSeries 24-Inch Sand Filter (SKU: PST-W3S244T2) pairs a corrosion-proof polymeric tank with a 2 inch VariFlo top-mount multiport valve, giving your inground pool 3.14 sq ft of filtration area and a 62 GPM design flow rate in a single bolt-on assembly. The umbrella-fold self-cleaning lateral system spreads incoming water evenly across 300 lbs of sand, so debris is captured efficiently and backwashes restore flow without channeling. You get a flange clamp valve that rotates a full 360 degrees for easier plumbing, a built-in sight glass, and a pressure drain port that makes winterizing fast.
Umbrella-Fold Self-Cleaning Laterals
You get longer filter cycles and cleaner water because the precision-engineered umbrella-fold lateral system opens during backwash to scour every grain of sand. Flow is distributed evenly across the full 3.14 sq ft media bed instead of channeling through a narrow strip, so the sand actually traps debris instead of letting it slip through. Balanced backwashing also means less wasted water and shorter cycles when you flip the VariFlo handle to clean the bed.
Built to Outlast the Weather
The tank is molded from rugged polymeric resin that shrugs off UV, pool chemicals, freeze cycles, and ground moisture, so a pad-mounted W3S244T2 keeps doing its job season after season without rust streaks, paint flaking, or seam leaks. The integral base is part of the same molded structure, not a bolt-on accessory, which removes one more failure point. Rated for 50 PSI maximum working pressure with a generous safety margin built in.
2 Inch VariFlo Valve, 360 Degree Rotation
The included 2 inch VariFlo top-mount multiport valve handles Filter, Backwash, Rinse, Waste, Recirculate, Closed, and Winterize from a single lever-action handle, so changing modes takes a second. The flange clamp design lets the valve rotate a full 360 degrees on the tank, so you can line port connections up with existing returns and pump plumbing instead of fighting them. A built-in sight glass shows when backwash water runs clear, taking the guesswork out of cycle timing.
Who It's For
Inground Residential Pools
Sized for inground pools up to roughly 37,200 gallons on a 10-hour turnover, or 29,760 gallons on an 8-hour turnover. A strong fit for typical 18 by 36 ft and 20 by 40 ft backyard pools.
Inground Spas and Water Features
The same 2 inch porting works for inground spas, spillways, and decorative water features that need durable, low-maintenance sand filtration without bumping up to a 30 inch tank.
Equipment Pad Upgrades
Drops in as a direct replacement on most existing concrete pads. The 24.5 inch footprint and 18 inch side clearance requirement make it easy to retrofit without re-pouring or moving plumbing.
Vinyl, Fiberglass, and Gunite
Works equally well on vinyl liner, fiberglass, and gunite pools. Sand media handles seasonal pollen, fine grit, and algae bloom debris better than many low-end cartridge setups.
Why PST Customers Pick This
62 GPM Design Flow
Matches up cleanly with 1 HP and 1.5 HP single-speed pumps and most variable-speed setups at typical filter speeds.
Easy Sand Servicing
Large fill opening accepts standard 50 lb sand bags. Six bags of #20 silica gets you to the 300 lb load line.
1.5 Inch Drain Port
Oversized pressure drain port empties the tank fast for winterizing or media changeouts, so you skip the siphon hose routine.
7-Position VariFlo Valve
Filter, Backwash, Rinse, Waste, Recirculate, Closed, and Winterize on one lever. No dial twisting, no guesswork.
24.5 in Footprint
Slots into the same pad space as competing 24 inch sand filters. 42 inch total height with valve attached.
Corrosion-Proof Build
Polymeric tank, stainless hardware, and chemical-resistant internals stand up to chlorinated and salt-treated water alike.
Plumbing Notice
Plumbing connections should be made by a qualified pool professional and pressure-tested before startup. The tank is rated to 50 PSI maximum working pressure, so verify your pump curve and any pressure-side accessories before pressurizing. Always release pressure and open the air relief before opening the valve or tank lid.

Frequently Asked Questions
What is the difference between the W3S244T2 and the W3S244T?
Both filters use the same 24 inch tank and 3.14 sq ft sand bed. The W3S244T2 ships with the 2 inch VariFlo multiport valve, while the W3S244T ships with the 1.5 inch valve. If your existing plumbing is 2 inch, choose the W3S244T2 for less head loss and better flow on variable-speed pump installs.
What size pool does this filter handle?
The W3S244T2 turns over roughly 37,200 gallons every 10 hours or 29,760 gallons every 8 hours. That covers most residential inground pools up to about 24,000 to 30,000 gallons comfortably, including standard 18 by 36 and 20 by 40 ft rectangles.
What pump should I pair with this filter?
Match the W3S244T2 with any pump that delivers up to 62 GPM at typical filter pressure. 1 HP and 1.5 HP single-speed pumps like the Hayward Super Pump and TriStar work well, and variable-speed pumps such as the Hayward TriStar VS and Super Pump VS pair cleanly with the 2 inch porting.
How much sand do I need and what type?
You need 300 lbs of #20 silica pool filter sand, which is six standard 50 lb bags. Do not use playground sand or masonry sand. ZeoSand and glass media are options if you want longer service intervals, but follow the alternate-media fill chart, not the silica figure.
Can I install this myself?
Mechanically yes, this is a homeowner-friendly install if you are comfortable with pool plumbing. You set the tank on a level pad, connect 2 inch PVC unions to the pump, return, and waste lines, load the sand, and start up in Backwash. If you are not comfortable working with PVC and pressure systems, hire a pool pro to handle the plumbing and pressure-test.
Is this an aboveground or inground filter?
This is an inground filter. The ProSeries lineup is rated for inground pools, spas, and water features. Hayward sells separate filter families for aboveground pools, so do not substitute this model for an aboveground tank kit.
How often do I need to backwash and replace the sand?
Backwash when the pressure gauge climbs about 8 to 10 PSI above the clean starting pressure, which is typically every 1 to 2 weeks during the swim season. Plan on a full sand changeout every 5 to 7 years on average, sooner if you fight heavy debris or hard water.
