Pentair 27-1/4" Center Piping Assembly with Hub

The Pentair 27-1/4" Center Piping Assembly with Hub (part number 155323) is a critical internal plumbing component specifically engineered for the Pentair Tagelus TA100 and TA100D series pool and spa sand filters. This specialized assembly consists of a long, rigid PVC center standpipe factory-bonded to a multi-port distribution hub located at the bottom, which serves as the foundational mounting block for the filter's lateral fingers. Its primary function is to route filtered water from the bottom of the sand bed back up through the multi-port valve and out into the pool system, ensuring balanced hydraulics and preventing sand media from escaping into the pool. Constructed from high-impact, chemical-resistant polymer materials to withstand continuous water pressure and chemical exposure, this elongated internal piping component carries a shipping and overall product weight of approximately 4.60 pounds, providing a substantial yet manageable replacement assembly for maintaining proper filtration flow rates.
