Product Overview

The Pentair 155063 center piping assembly with hub forms a key part of the internal plumbing structure inside pool and spa sand filters. Installed in the center of the filter tank, the assembly connects the lateral system at the bottom of the tank to the standpipe that routes water back to the filter outlet.

During filtration, water flows through the sand media where debris is captured. The lateral system collects the filtered water and directs it through the hub and center piping assembly before returning it to the circulation system. Replacing a damaged or worn center piping assembly restores proper internal water routing and helps maintain efficient sand filter operation.
