Pentair 2" HiFlow Bottom Valve with Gasket

The Pentair 2" Hi-Flow™ Bottom Valve Plate with Gasket (Product #: 272433) is a factory-original OEM replacement sub-assembly engineered to completely restore the internal water containment and directional routing of 2-inch multi-port backwash valves. Designed as a direct-fit bottom rebuild kit for heavy-duty Pentair, PacFab, and Sta-Rite® 2-inch side-mount and top-mount six-position multiport valves—commonly paired with large Triton® sand filters and FNS® Plus or Quad D.E.® vertical grid systems—this module serves as the lower floor configuration that anchors the fluid chambers. The assembly consists of a rugged structural bottom plate injection-molded from a thick-walled, glass-filled engineering thermoplastic composite, arriving with a pre-seated, custom-molded high-density rubber diverter spider gasket (Product #: 272409). When bolted or compressed within the primary valve body housing, this component establishes an absolute mechanical seal between separate water ports, preventing pressurized pool water from cross-contaminating chambers or chronically weeping down the waste line during standard filtration. Engineered to comfortably manage heavy hydraulic surges and high-velocity circulation loads at baseline operating pressures up to 50 PSI, the composite resin provides complete immunity to aggressive pool chemistry, salt-chlorine generation, and localized thermal friction. The physical dry weight of this Pentair 2" HiFlow Bottom Valve with Gasket assembly is approximately 2.50 pounds (with a packaged shipping weight of roughly 2.60 pounds), offering a durable, pre-fabricated, and highly reliable internal hardware solution for flawless pool fluid management.
