Hayward ProSeries W3S210T93S 21-Inch Sand Filter System with 1.5 HP Pump for Above-Ground Pools
The W3S210T93S is the largest system in the ProSeries above-ground sand filter lineup, pairing a 21-inch filter tank with a 1.5 HP PowerFlo Matrix pump. The 21-inch tank holds 200 lbs of sand and provides 2.20 sq ft of filtration area, making it the right choice for larger above-ground pools where the 18-inch models would need to work harder to maintain water clarity under sustained use. Everything ships factory-matched: filter, 7-position Vari-Flo valve, pump, base, and two hoses.
Hayward W3S210T93S ProSeries Sand Filter System Key Features
- 21-inch ProSeries filter tank - The largest tank in this above-ground lineup. 200 lbs of sand and 2.20 sq ft of filtration area provide substantially more capacity than the 18-inch models, with longer intervals between backwash cycles at equivalent pool volumes and debris loads.
- 1.5 HP PowerFlo Matrix above-ground pump - Matched to the 21-inch filter's 37 GPM design flow rate. Clear strainer cover, oversized basket, stainless steel shaft, and thermal overload protection.
- 7-position Vari-Flo top-mount valve - Filter, Backwash, Rinse, Waste, Recirculate, Closed, and Winter. Integral sight glass for backwash confirmation. 360-degree flange clamp rotation.
- Integral top diffuser - Even water distribution across the full sand bed on entry, maximizing use of the entire filtration area.
- Umbrella-fold self-cleaning laterals - Full 360-degree slotted laterals for energy-efficient operation and thorough, balanced backwashing.
- Pump-to-filter union connection - Simplifies installation and makes seasonal disconnection straightforward.
- One-piece base and two hoses - Stable mounting platform and hose pack for a standard above-ground pool connection, included.
- System dimensions - Approximately 31"L x 20"W x 40"H assembled.
Hayward W3S210T93S ProSeries 21-Inch Sand Filter System Specifications
Sand not included. Use #20 silica pool filter sand only. Pool coverage depends on pump output at actual system head and turnover rate targets.

Maintaining the Hayward W3S210T93S ProSeries Sand Filter System
Backwash when pressure rises 8 to 10 PSI above the clean baseline. Switch to Backwash until the sight glass clears, then Rinse 15 to 30 seconds before returning to Filter. The larger 200 lb sand bed will generally allow longer intervals between backwash cycles than the 18-inch models at equivalent pool volumes. Sand typically lasts 3 to 5 years.
First Startup: Loading Sand
Fill the tank halfway with water before adding sand to cushion the laterals. Add 200 lbs of #20 silica sand gradually. Run a Rinse cycle before switching to Filter to flush fine dust. Record the post-Rinse pressure as the clean baseline for all future backwash decisions.
Winterizing the W3S210T93S
Backwash before shutdown. Drain the filter tank through the base drain and leave the plug out. Set the valve to Winter to drain the valve body. Disconnect hoses and store the system indoors above freezing. The 6 ft power cord allows the pump to be stored away from the equipment pad easily.
Hayward W3S210T93S ProSeries Sand Filter System Frequently Asked Questions
Why choose the W3S210T93S over an 18-inch system?
The 21-inch tank holds 200 lbs of sand (vs. 150 lbs) and provides 2.20 sq ft of filtration area (vs. 1.75 sq ft). For larger above-ground pools or pools with higher debris loads, the additional capacity reduces how often you need to backwash and keeps the filter operating at lower pressure over the course of a season. If your pool is smaller and the 18-inch models have adequate headroom, the W3S180T93S offers the same 1.5 HP pump at a lower price point.
Does this system include sand?
No. 200 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.
Is this system suitable for in-ground pools?
No. The PowerFlo Matrix pump is an above-ground pump designed for hose-based plumbing. It is not suited for in-ground pool plumbing configurations.
Can the pump and filter be replaced independently?
Yes. Both components are discrete. If the pump fails, it can be replaced with a compatible above-ground pump without replacing the filter. Refer to the parts diagram for part numbers.
What electrical supply does this system need?
The pump comes with a 6 ft cord for a standard 115V GFCI-protected outdoor outlet. A GFCI-protected circuit is required. Never connect pool pump equipment to a circuit without GFCI protection.
