Description

The Pentair Strainer Eco/Tr (Part Number 150035) is a small but important part in your filtration system. Its purpose is to strain debris from the air relief line, helping trapped air escape and avoiding air lock, which can compromise filter efficiency. It fits into the air relief tube arrangement of Pentair Triton II, TR100C, TR140C, and C-3 models made after 11/1/1999. With precise dimensions and material compatibility, it’s designed for plug-and-play replacement. Keeping the air relief components clean and properly assembled ensures smoother filter operation and reduces risk of damage from pressure anomalies.

Pro Tip

Inspect the air relief tube and its O-ring when replacing this strainer—wear or buildup there often causes leaks or restricted flow. Install all parts dry, then apply a small amount of silicone or compatible lubricant if the O-ring is dry. Tighten gently to avoid damaging threads or cracking plastic.

Installation Tips

Always depressurize filter before removing strainer. Match manufacture date—this strainer is for units built **after** 11-1-1999. Use correct size tubing (3/8″ OD) and avoid forcing components—hand tight plus small increment is sufficient.
