Hayward 22 Inch Sand Filter

Hayward Pro Series 22" Top-Mount Sand Filter (W3S220TC)

Deliver crystal-clear water clarity and dependable, low-maintenance performance to your pool setup with the Hayward Pro Series 22-Inch Sand Filter. Engineered for both high-efficiency inground and permanent above-ground swimming pools, this robust system features Hayward's advanced Full-Flow hydraulic technology. By maximizing fluid movement and reducing internal plumbing friction, the filter achieves complete daily water turnover in fewer operational hours, helping to lower your circulation pump's electrical consumption.

The rugged, weather-proof filter body is injection-molded from a specialized, color-fast polymeric material engineered to resist UV degradation and high operational pressures. Topped with a patented, heavy-duty 7-position multi-port valve and arriving with 3 feet of specialized connection hose, this system makes reversing water flow for seasonal debris flushing simple and tool-free.

Advanced Hydraulic Engineering & Balanced Bed Filtration

• Cascading Top Diffuser: Outfitted with an integrated internal top diffuser that evenly distributes incoming unfiltered water over the entire sand media bed in a wide, umbrella-like pattern. This design eliminates physical channeling and extracts maximum filtration efficiency from every square inch of sand.

• 360° Slotted Underdrain Laterals: Features a high-velocity, self-cleaning underdrain assembly built with 360-degree slotted laterals. This ensures a balanced return of sparkling water to the pool while enabling exceptionally thorough backwashing cycles.

• Unitized Polymeric Tank Hull: The one-piece structural shell is molded from tough, color-fast polymeric composites to guarantee complete corrosion-proof performance and fade resistance under direct sunlight for years to come.

• Optimized Flow Profile: Engineered to support a continuous Design Flow Rate of 52 GPM, making it an exceptional hydraulic match for standard residential pumps and modern variable speed setups.

📊 Dependable Mechanical Filtration with Low Overhead

Sand filtration remains a premier choice for pool owners seeking crisp water filtration without the ongoing, expensive overhead of replacing fabric cartridges or delicate D.E. grids. When your integrated pressure gauge indicates a 7–10 PSI rise over your clean system baseline, simply shut off your pump, depress the valve handle, rotate it to the "Backwash" position, and let the 360° internal lateral network rapidly flush trapped dirt and organic particulate straight down your waste line.

⚠️ Installation, Sizing & Crucial Winterization Rules

• Factory Warranty Parameters: Backed by a 1-Year Limited Manufacturer’s Warranty covering factory defects in structural materials and workmanship under ordinary usage.

• Absolute Freeze Expansion Warning: The factory warranty does not cover structural splitting, hairline cracking, or valve ruptures caused by freeze expansion or residual ice formation. In cold-weather climates, the tank must be completely drained of water via the lower drain fitting, and the plumbing lines must be blown out prior to sub-zero winter temperatures.

• Media Sizing Compliance: Operating this filter with incorrect sand grades, fine play sand, or uncertified aggregate will ruin the internal lateral slots, blow media back into your pool return lines, and void all warranty coverages. Use exclusively standard #20 Silica Sand or certified glass alternatives.

• Professional Trade Recommendation: Damage resulting from improper mechanical anchoring, over-pressurization past factory specifications, or incorrect pipe gluing will void the warranty. Professional installation by a licensed pool technician is highly recommended.

📞 Hydraulic Sizing & Connection Layout Support: Matching a 22-inch sand filter requires ensuring your pump’s flow output aligns safely with the 52 GPM design target to avoid over-pressurizing the valve assembly or driving sand back into your return lines.
