Pentair Lower Piping Assembly TR60

The Pentair Lower Piping Assembly for TR60 is a crucial internal plumbing manifold engineered exclusively for the Pentair Triton® II Side-Mount Sand Filter (Model TR60). Depending on the manufacturing date of the filter tank, this component is available under two distinct configurations: Part #154805 (for TR60 models manufactured before June 2007 utilizing threaded hub/laterals) and Part #155284 (for "ClearPro Technology" TR60 models manufactured after June 2007).

Functional Overview

Molded from heavy-walled, chemical-resistant PVC, this assembly sits at the absolute baseline of the filter vessel underneath a massive bed of filtration sand. It acts as the primary hydraulic gateway connecting the filter's external multi-port backwash valve bulkheads to the internal bottom hub matrix (which houses the 8 slotted lateral fingers).

During standard filtration cycles, water is pushed down through the sand bed, where micro-particulates are trapped. The clean water then enters the lower lateral fingers, collecting inside the central hub. The lower piping assembly channels this high-volume stream back out of the pressurized tank and returns it cleanly to the pool. Conversely, during a backwash cycle, this pipe reverses the flow, forcing high-pressure water outward through the laterals to lift and rinse trapped organic matter out to waste. By maintaining an uninhibited, rigid conduit, it prevents internal water bypass and protects the lower vessel from localized pressure spikes.

Weight and Dimensions Profile

Because this assembly consists of highly compact, dense plumbing connections, its physical weight profile remains balanced and manageable:

• Actual Product Weight: Approximately 1.2 to 1.24 pounds (roughly 19 to 20 ounces).

• Physical Footprint: Features standard 2-inch internal plumbing thread interfaces, with average box transit boundaries spanning roughly 12" x 5.5" x 3.75" up to 18" x 13" x 2" depending on the specific pipe branch extensions included in the layout.

• Packaged Shipping Weight: Typically scales between 1.5 and 2.5 pounds to accommodate the protective cardboard packaging and bubble insulation needed to ensure the rigid plastic thread collars do not crack or fracture during transit.
