OEM lower piping assembly for Pentair Triton II TR50 sand filters. Restores proper flow and filtration.

- Lightweight design simplifies handling during service
- Restores filtration integrity following damage or leaks
Description
This lower piping assembly (SKU 156816) serves as the core internal manifold in the Pentair Triton II TR50 sand filter. If the original lower manifold cracks, warps, or leaks—common failure points in aging systems—water may bypass or fail to evenly reach all laterals. Installing this OEM-grade replacement restores structural integrity, ensures balanced flow, and helps maintain optimal filtration. Built from chemical-resistant molded plastic, it tolerates everyday pool conditions and adds long-term durability to your filter’s internal plumbing.
Pro Tip
Always inspect matching internal parts such as the upper piping (156814) and lateral grids when servicing. Replacing all compromised internal plumbing at once helps reduce recurring leaks.

Installation Tips
Always depressurize and fully drain the filter before opening. Check and replace any O-rings or seals during reassembly. Avoid over-torquing to prevent cracking the plastic.
