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.
