Pentair Triton II TR140 Upper Piping Assembly

The Pentair Triton II TR140 Upper Piping Assembly (part number 154500) is a specialized internal manifold component engineered exclusively for the high-capacity, 36-inch diameter Pentair Triton II TR140 side-mount sand filtration system. Injection-molded from heavy-walled, high-impact PVC and ABS thermoplastic polymers, this rigid plumbing configuration positions itself at the top section of the filter's interior. Its primary operational role is to receive incoming pool water from the external multiport valve and distribute it smoothly through the top diffuser dome, ensuring an even, low-velocity spread over the sand media bed while preventing the forceful displacement or channeling of the underlying silica sand. This rigid overhead framework also anchors the internal air relief line, enabling the system to safely vent compressed gas pockets and maintain a flooded hydraulic state under continuous operating pressures up to 50 PSI. Engineered to endure continuous submersion in highly chlorinated water, abrasive media friction, and intense backwash flow reversals, its robust, multi-port plastic pipe construction is built for long-term structural durability. Because of its expansive, thick-walled configuration customized for the largest filter in the Triton II lineup, the individual upper piping assembly carries a net product and shipping weight of approximately 1.85 to 2.20 pounds (about 29.6 to 35.2 ounces).
