Product Overview

The Pentair 24600-0003 HRPB20 lateral tube is an essential component used within Pentair high-rate sand filtration systems. Installed at the bottom of the filter tank, the lateral tube works with the hub assembly and other lateral arms to form the underdrain system that distributes water evenly across the sand bed.

During filtration cycles, water flows through the sand media where dirt and debris are captured. The lateral assembly then collects the filtered water and directs it back through the standpipe and outlet plumbing. Replacing a damaged or worn lateral tube helps restore proper water distribution and ensures reliable filtration performance in HRPB20 sand filter systems.
