Hayward ProSeries Sand Filter Inground 24 In Top Mount 2 Inch Valve

The Hayward ProSeries W3S244T2 is a 24-inch top-mount sand filter for in-ground pools with a 2-inch Vari-Flo valve. Same tank, sand capacity, and flow rate as the W3S244T — the difference is the larger valve for higher-flow plumbing systems. Sand not included. Hayward ProSeries W3S244T2 24-Inch Top-Mount Sand Filter with 2-Inch Valve for In-Ground Pools The W3S244T2 uses the same 24-inch ProSeries tank as the W3S244T — 3.14 sq ft of filtration area, 300 lbs of sand, 62 GPM. The distinction is the valve: the T2 ships with a 2-inch Vari-Flo top-mount multiport valve rather than a 1.5-inch. The larger valve reduces head loss through the valve body at high flow rates and is the correct choice when your plumbing is 2-inch throughout, your pump output is near the 62 GPM ceiling, or you are replacing a system that was originally plumbed with 2-inch connections. If your plumbing is 1.5-inch and your pump output is comfortably below 62 GPM, the W3S244T delivers the same filtration performance at a lower price point. Hayward W3S244T2 ProSeries 24-Inch Sand Filter Key Features 2-inch Vari-Flo top-mount valve - The larger port reduces pressure drop through the valve at high flow rates compared to the 1.5-inch valve. Suited to 2-inch plumbing systems and installations where the pump operates near the filter's 62 GPM flow ceiling. 24-inch tank with 3.14 sq ft of filtration area - 300 lbs of sand, 62 GPM design flow rate. Identical tank to the W3S244T; the valve is the only difference between the two models. 7-position Vari-Flo valve - Filter, Backwash, Rinse, Waste, Recirculate, Closed, and Winter positions. Integral sight glass and 360-degree flange clamp rotation. Full-size internal piping - Smooth, free-flowing internal path matched to the larger 2-inch valve connections. 360-degree self-cleaning laterals - Balanced backwashing across the full sand bed base. Integral top diffuser - Even incoming water distribution across the sand surface. Corrosion-proof reinforced thermoplastic tank - All-weather outdoor construction. Large pressure sand/water drain - Fast seasonal draining and sand replacement.

Run Backwash until the sight glass clears, Rinse 15 to 30 seconds, then return to Filter. Replace sand every 3 to 5 years. First Startup: Loading Sand Fill the tank halfway with water before adding sand to protect the laterals. Add 300 lbs of #20 silica sand gradually. Run a Rinse cycle before switching to Filter. Record the post-Rinse pressure as the clean baseline. Winterizing the W3S244T2 Backwash before shutdown. Drain the tank through the base drain and leave the plug out. Set the valve to Winter to drain the valve body. Blow out with compressed air in hard-freeze climates. Hayward W3S244T2 ProSeries 24-Inch Sand Filter Frequently Asked Questions What exactly is different between the W3S244T and W3S244T2? Only the valve. The W3S244T2 includes a 2-inch Vari-Flo multiport valve; the W3S244T includes a 1.5-inch valve. The tank, sand capacity, filtration area, and flow rate are identical. Choose the T2 if your pool plumbing uses 2-inch pipe, if your pump output is near the 62 GPM ceiling, or if you are replacing a system that was originally installed with a 2-inch valve. Does the W3S244T2 include sand? No. 300 lbs of #20 silica pool filter sand must be purchased separately. Fill the tank halfway with water before adding sand to protect the lateral assembly. Does the larger valve increase the filter's flow rate? No. The filter's design flow rate is 62 GPM regardless of valve size. The 2-inch valve reduces head loss through the valve body itself at high flow rates, which means less resistance in the system — not a higher flow ceiling for the filter. When should I step up to the W3S270T2 instead? If your pump output at operating head exceeds or consistently approaches 62 GPM, the W3S270T2 (27-inch, 75 GPM, 2-inch valve) is the appropriate next step. It shares the same 2-inch valve configuration with more sand capacity and a higher flow ceiling.
