Pentair Star System Pump-to-Filter Piping Assembly

The Pentair Star System Pump-to-Filter Piping Assembly (part number 750016) is a specialized structural plumbing connector engineered exclusively for above-ground pool and spa equipment pads. This replacement conduit is standard hardware for Pentair Star Polymeric above-ground networks and Star series Diatomaceous Earth (D.E.) modular media filter systems, typically pairing the vessel directly with a high-performance Dynamo or OptiFlo pump.

Injection-molded from a heavy-walled, high-impact, and chemically inert polymer compound, this rigid manifold pipe acts as the primary pressurized gateway between the pump's discharge mouth and the filter's inlet port or multi-port backwash valve. Its primary operational role is to cleanly transfer turbulent, high-velocity water pushed from the pump impeller straight into the filtration tank core, minimizing hydraulic restriction and maintaining a highly organized, balanced fluid velocity. The pre-formed modular kit includes the specialized unyielding pipe section along with its matching connection fittings and high-density elastomeric O-rings. When locked hand-tight over its integrated seats, it establishes an absolute watertight compression boundary that enables the combined equipment pad configuration to safely sustain continuous internal operating pressures up to 50 PSI without weeping, experiencing localized thread stress, or vibrating loose under intense pump motor surges.

Engineered to endure decades of demanding outdoor equipment pad weathering, direct sunlight UV exposure, and intense shifting seasonal thermal stresses, its rugged composite design completely resists material structural degradation, environmental stress-cracking, and chemical bleaching from direct splashing or contact with highly concentrated pool sanitizers like chlorine, bromine, and winterizing acid washes. Due to its solid, thick-gauge molded plastic geometry and included union hardware components, this individual pump-to-filter piping assembly carries a net product weight of approximately 1.45 pounds with a shipping weight profile of 1.50 to 1.75 pounds.
