Pentair Triton II TR100 Upper Piping Assembly

The Pentair Triton II TR100 Upper Piping Assembly (part number 154426) is a critical internal plumbing manifold component designed exclusively for the top configuration of the high-capacity, 30-inch diameter Pentair Triton II side-mount pool and spa sand filtration systems (model TR100). Injection-molded from thick-walled, high-impact Schedule 80 PVC thermoplastic polymer, this rigid pipe assembly spans the upper interior portion of the fiberglass tank chassis, interfacing directly between the upper bulkhead and the distribution diffuser dome. Its primary operational role is to receive incoming, high-velocity pool water from the system's external multi-port or slide valve and cleanly direct it toward the top diffuser assembly, transforming a turbulent hydraulic stream into an evenly distributed blanket across the underlying silica sand bed. This precise fluid dynamic regulation maximizes the filtration surface area, prevents high-pressure water from carving channels through the sand media, and ensures the pressure vessel safely sustains continuous operational loads up to 50 PSI without fluid bypass or structural vibration fatigue. Built to remain permanently submerged in a highly dynamic, chemically aggressive environment, its robust plastic framework resists structural warping, cracking, and corrosive breakdown from high-strength pool sanitizers like chlorine, bromine, and winterizing acid washes. Due to its thick-walled PVC construction and specialized fluid-handling geometry, this individual upper interior piping assembly carries a net product and shipping weight of approximately 1.15 to 1.35 pounds (about 18.4 to 21.6 ounces).
