Pentair Valve for FullFloXF Filter

The Pentair FullFloXF® High-Performance Backwash Valve (Product #: 263080 / 263081) is a commercial-grade, ultra-high-efficiency water routing manifold engineered to deliver near-zero hydraulic pressure drop across premium pool and spa filtration loops. Designed as a hydraulically optimized companion for high-capacity filters—including the Triton® II sand series, Quad D.E.®, FNS® Plus, and System:3® modular D.E. tanks—this valve features a massive 3-inch outside diameter (OD) and 2.5-inch inside diameter (ID) internal flow profile. By providing an completely unrestricted, straight-through fluid path, it significantly slashes systemic backpressure, allowing modern variable-speed pumps to run at lower, energy-saving RPMs while remaining fully California Title 24 compliant for 2-inch, 2.5-inch, or 3-inch equipment pad plumbing. Injection-molded from thick-walled, corrosion-resistant PVC, the robust housing features an ergonomic, over-molded comfort-grip lever that locks smoothly into six manual positions (Filter, Backwash, Rinse, Waste, Closed, and Recirculate), supported by a heavy-tension stainless steel internal spring and removable structural end caps that streamline seasonal o-ring lubrication and field maintenance. The physical dry weight of the standard Pentair FullFloXF Valve assembly is approximately 11.6 pounds (with a boxed shipping weight of roughly 12.5 to 16.8 pounds depending on the specific inclusion of the 2-inch or 2.5-inch quick-disconnect plumbing union adapter kits), offering an incredibly robust, energy-efficient, and long-lasting plumbing solution for high-velocity pool water circulation.
