Hayward Selectaflo DE Filter Valve 2" SKT x 2.5" SPG | SP0425 4-Position Side Mount

Hayward SP0425 Selectaflo High-Efficiency DE Filter Valve

Optimize your pool’s circulation and filtration with the Hayward SP0425 Selectaflo Valve. Engineered specifically for vertical grid D.E. filters, this 4-position side-mount valve features a high-efficiency design that reduces internal flow resistance. By allowing water to move more freely, it helps your pump work less while maintaining superior water clarity.

This valve is the professional choice for those looking to maximize the performance of their Hayward ProGrid or DEP 500 Series filtration systems.

4-Position Functionality:

• Filter: For normal filtration and daily pool vacuuming.
• Backwash: To clean the filter by reversing the flow and flushing out debris.
• Waste: For bypassing the filter to lower water levels or vacuum heavy debris directly out of the pool.
• Recirculate: Circulates water without passing through the filter—ideal for chemical treatments.

Technical Specifications:

• Plumbing Connections: 2" Socket (Internal) x 2.5" Spigot (External) for maximum flow.
• Mounting: Side-mount configuration (includes union nuts and gaskets).
• Compatibility: Designed for Hayward ProGrid and DEP 500 Series DE Filters.
• Bonus Feature: Includes an EcoFlo fitting specifically for TriStar pump integration.

Why Choose Selectaflo?

• Lower Energy Costs: Reduced hydraulic resistance means your pump can run at lower speeds (if variable speed) or pull less amperage.
• Simple Operation: The ergonomic 4-position handle is easy to turn and clearly marked, taking the guesswork out of maintenance.
• Rugged Durability: Injection-molded from reinforced thermoplastic to withstand high pressures and harsh winter climates.

🚩 PRO TIP: The "Gasket Guard" Method To prolong the life of your internal diverter gasket, always turn off the pump before moving the valve handle. Snapping a photo of your existing plumbing before removal will ensure your new SP0425 is lined up perfectly for a leak-free "first-time" seal!
