Hayward 30 Inch Pro Series Sand Filter

## Hayward Pro Series 30" Top-Mount Sand Filter (W3S310T2)

Deliver pristine, sparkling water clarity to your large inground pool with the Hayward Pro Series 30-Inch Sand Filter. Engineered for high-performance circulation, this rugged filtration system blends a durable, weather-proof design with advanced fluid dynamics. It features Hayward's patented **Full-Flow hydraulic technology**, which minimizes resistance to water flow, maximizing filtration efficiency so you can achieve complete daily water turnover in significantly fewer hours, driving down your pump's electricity consumption.

Molded from a tough, color-fast polymeric material, the heavy-duty tank stands up to brutal environmental conditions and high pressure. Equipped with a patented, easy-to-use **7-position top-mount Multi-Port valve**, reversing water flow to flush out captured debris via backwashing is completely effortless.

### Advanced Hydraulic Engineering & Even Bed Filtration
*   **Cascading Top Diffuser:** Outfitted with an integrated top diffuser that distributes unfiltered water evenly across the entire sand media bed in a wide, umbrella-like pattern. This eliminates channeling and extracts maximum filtration performance from every square inch of sand.
*   **360° Slotted Laterals:** The self-cleaning underdrain assembly utilizes 360-degree slotted laterals to provide a highly balanced, rapid return of crystal-clear water back to the pool, while enabling exceptionally thorough and balanced backwashing.
*   **Rugged Polymeric Hull:** The weather-proof, single-piece filter body is injection-molded from specialized polymeric materials, ensuring absolute corrosion-proof operation and fade resistance under direct sunlight for years to come.
*   **Massive Fluid Capacity:** Optimized to handle high structural volumes with a rated **Maximum Flow Rate of 98 GPM**, making it the perfect equipment pad companion for large inground pools and high-capacity variable speed pumps.

### 📊 Heavy-Duty Performance, Low Maintenance Overhead
Sand filtration remains a premier choice for pool owners seeking reliability and exceptionally low maintenance costs. Unlike other systems, there are no delicate grids or elements to drop or replace. When the integrated pressure gauge indicates a 7–10 PSI rise over your baseline clean pressure, simply shut off your pump, depress the heavy-duty valve handle, rotate it to the "Backwash" position, and let the 360° internal laterals rapidly flush out captured debris.

### ⚠️ Installation, Sizing & Winterization Warranty Guidelines
*   **Factory Warranty Policy:** Backed by a 1-Year Limited Manufacturer’s Warranty covering defects in structural materials and expert workmanship. 
*   **Exclusions & Freeze Warnings:** The factory warranty **does not cover** secondary labor charges, the cost of lost pool water/chemicals, or tank cracking caused by expanding ice. To prevent winter shell splitting in freezing climates, the tank must be completely drained via the bottom drain plug and lines blown out prior to sub-zero winter weather.
*   **Media Notice:** Operating the filter with incorrect sand sizing or non-pooling aggregate voids the warranty and will result in media blowing backward into your pool return lines. Use exclusively standard #20 Silica Sand or certified glass alternatives.
*   **Professional Alignment:** Damage caused by improper plumbing initialization or excessive water-hammer pressure spikes voids the product warranty. Professional installation by a licensed pool technician is highly recommended.
