Restore your filtration control with the Hayward SP410X502S 2-Inch Backwash Slide Valve. Engineered for maximum flow and minimal resistance, this OEM push-pull valve is the gold standard for side-mount DE and sand filter systems.

Key Features

• Full-Flow 2" Plumbing: Designed with 2-inch socket (SKT) ports to handle high flow rates (up to 150 GPM) while reducing system backpressure.
• Rugged Construction: Crafted from Hayward’s proprietary PermaGlass XL® thermoplastic for superior chemical resistance and long-term durability.
• Effortless Operation: The simple push-pull piston design eliminates the complexity of multiport valves, reducing the risk of internal leaks and clogs.
• Direct OEM Fit: Specifically designed for Hayward Pro-Grid™ and Micro-Clear™ vertical grid DE filters.
• All-In-One Assembly: Comes ready for installation, typically including the union nuts and internal piston assembly.

🚩 Pro Tip: Before gluing the socket connections, remove the internal piston assembly! This prevents accidental glue drips from seizing the valve. Once installed, apply a thin layer of silicone lubricant to the piston O-rings annually for a buttery-smooth operation.
