The Pentair TR40 Lower Pipe Assembly (SKU 154801) is the OEM replacement piping component used in Triton II TR40 sand filters. It connects and aligns lower lateral lines with the main drain and underdrain system, maintaining optimal flow and filtration performance. Crafted from robust, chemical-resistant materials, this assembly is designed to withstand continuous exposure to water, filtration backwash cycles, and pool chemicals without warping or degradation. Its precision molding ensures a tight fit in the filter tank, reducing leakage, inefficiencies, and wear on adjacent components.
Pro Tip
When replacing the lower pipe assembly, install new laterals at the same time if they show wear. Use a gentle lubricant on seals during assembly to prevent pinching, and always run a short rinse cycle before resuming normal filtration.
Installation Tips
Ensure the filter is depressurized and power is off before servicing. Confirm compatibility with your TR40 filter model. Avoid overtightening; ensure proper alignment of all lateral pipes before sealing the tank.
