Pentair TR100C Upper Pipe Assembly

The Pentair TR100C Upper Pipe Assembly is a vital internal plumbing component engineered for the Pentair Triton® C and Triton® C-3 Commercial Side-Mount Sand Filters (TR100C and TR140C). Molded from heavy-duty, commercial-grade PVC and ABS composites, this upper manifold connects to the filter's internal side bulkheads to receive raw, high-velocity pool water from the circulation pump. It distributes this incoming flow evenly across the top of the sand bed via integrated diffuser channels, preventing a destructive phenomenon known as "channeling," where water carves a single direct path through the sand and bypasses proper filtration. By ensuring uniform water distribution across the media surface, the assembly maximizes fine particulate capture down to 20 microns while also providing integrated routing for the internal air-bleed tube to safely exhaust trapped air pockets. Depending on whether it is configured for a standard or heavy-duty commercial unit (such as Part #156344 or #156355), the assembly measures roughly 16 to 17 inches in length, carries an actual product weight between 0.84 and 1.97 pounds, and yields a packaged shipping weight of 1.5 to 3.0 pounds to protect its rigid layout during transit.
