Pentair 2" Valve Top Assembly

The Pentair 2" Hi-Flow™ Multiport Valve Top Assembly Replacement (Product #: 272422 / 270104Z) is a premium, factory-original OEM rebuild module engineered to completely restore the mechanical sealing and fluid-routing efficiency of high-capacity 6-way backwash valves. Designed as a drop-in, pre-assembled top cover solution for Pentair and PacFab 2-inch side-mount and top-mount valves, this assembly is commonly used to service large-scale residential filtration systems, such as Triton® II sand filters and Quad D.E.® separation tanks. The module eliminates the need for tedious, piece-by-piece internal overhauls by arriving fully populated with the heavy-duty black cover dome, a pre-indexed position label, a large one-piece positive-lock lever handle, a high-tension stainless steel compression spring, a heavy-gauge thrust washer, a pre-installed diverter shaft o-ring, and a durable internal diverter plate backed by a specialized rubber gasket. Injection-molded from a thick-walled, UV-stabilized engineering polymer, the housing provides absolute structural defense against aggressive pool chemicals, heavy mineral scaling, and continuous outdoor weathering under operational pressures up to 50 PSI. Swapping out the complete top assembly quickly resolves common filtration failures, such as water continuously weeping out of the backwash waste line, internal chamber fluid bypass, or a rigid, sticking handle mechanism. The unit aligns flawlessly over the existing valve body using a standard six-bolt perimeter configuration to compress the main flange tank seal. The physical dry product weight of this Pentair 2-inch multiport valve top assembly is approximately 3.5 pounds (with a boxed shipping weight of roughly 4.2 pounds), providing pool professionals and DIY homeowners with a rugged, time-saving, and highly dependable fluid-management solution.
