Description

The Pentair Pipe Assembly TR140 Lower (SKU 154489) is built with durability as a priority. As a core plumbing part of the filter’s underdrain system, it channels water uniformly into your lateral network, minimizing channeling and preserving filtration efficiency. Crafted from robust plastic, it withstands repeated cycles of pressure, temperature, and chemical exposure. Replacing this part restores original flow geometry and helps your sand media perform at its best.

Pro Tip

When replacing this lower assembly, check your laterals and hub O-rings too — a weak seal or cracked lateral will negate the benefits of a new lower plumbing. Use proper lube on O-rings and ensure alignment during reassembly.

Installation Tips

Be sure the filter is depressurized before disassembly. Align all tab or indexing features exactly. Use only correct lubricant on O-rings, and avoid cracking pressure by over tightening.
