Pentair Triton C Upper Pipe Connecting Assembly for Triton C Sand Filter

The Pentair Triton C Upper Pipe Connecting Assembly (part number 154591 or 154591Z) is a specialized internal plumbing component designed exclusively for the top-section distribution network of high-capacity Pentair Triton C and Triton C-3 commercial side-mount sand filtration systems. Injection-molded from thick-walled, high-impact PVC and ABS thermoplastic polymers, this rigid connecting manifold links the internal vertical plumbing mast directly to the upper diffuser dome. Its primary operational role is to receive incoming, high-velocity pool water from the external multiport or slide valve and route it smoothly into the upper 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 robust framework also securely anchors the internal automatic air relief line, enabling the system to continuously vent trapped air pockets and maintain a completely flooded hydraulic state under continuous operating pressures up to 50 PSI. Engineered to endure years of constant submersion in highly chlorinated pool water, abrasive media friction, and intense backwash flow reversals, its robust plastic architecture resists cracking and structural fatigue. Due to its thick-walled, elongated configuration tailored to manage high commercial flow rates, this individual upper pipe connecting assembly carries a net product and shipping weight of approximately 1.10 to 1.35 pounds (about 17.6 to 21.6 ounces).
