Pentair 1.5" Black Valve Top

The Pentair 1.5" Black Valve Top (Product #: 272511 / 272512) is a factory-original OEM replacement dome assembly engineered to completely restore the upper pressure-side containment and manual control of pool and spa sand filtration networks. Specifically designed to bolt onto classic black-bodied Pentair, PacFab, and Praher 1.5-inch top-mount and side-mount six-position multiport backwash valves—commonly installed on residential Sand Dollar® and Tagelus® filters—this heavy-duty cover plate serves as the structural anchor for the valve's mechanical indexing gear. Injection-molded from a premium, thick-walled engineering thermoplastic composite, the dome features a robust six-bolt perimeter configuration that aligns flawlessly over the existing valve body to compress the main flange gasket. This design ensures total immunity to aggressive pool chemicals, high salt levels, and continuous outdoor weathering, effectively preventing pressure-side water weeping or suction-side air induction under baseline operating pressures up to 50 PSI. The top surface features a molded index track designed to guide the manual selector handle smoothly into its six distinct operational detents (Filter, Backwash, Rinse, Waste, Closed, and Recirculate), providing the essential structural backstop against the high-tension internal compression spring. The physical dry weight of this single Pentair 1.5" Black Multiport Valve Lid is approximately 0.65 pounds (roughly 10.4 ounces, with a packaged shipping weight of approximately 0.85 pounds), delivering a rugged, long-lasting, and vital hardware replacement for efficient pool water management.
