Pentair Triton C Upper Pipe Assembly for Triton C Sand Filter

The Pentair Triton C Upper Pipe Assembly (part number 154599 or 154599Z) is a heavy-duty internal plumbing component designed exclusively for 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 manifold structure positions itself securely at the upper apex of the filter tank chassis. Its primary operational role is to receive incoming pool water from the external multiport or slide valve and distribute it evenly across the upper diffuser dome, creating a balanced, low-velocity flow over the dense media bed while preventing the forceful channeling or displacement of the underlying silica sand. This structural framework also anchors the internal automatic air relief lines, allowing 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 expansive, thick-walled configuration tailored to manage high commercial flow rates, this individual upper piping assembly carries a net product and shipping weight of approximately 1.85 pounds (about 29.6 ounces).
