Description

The Pentair TR40 Air Relief Tube (Part # 150039) performs a critical function: it routes air from the top of your filter tank out through the air relief port. Without it, air may accumulate, causing pressure build-up, reduced flow, or compromised backwash performance. This replacement tube is built for filters in the TR40 / Triton II line (after Nov. 1, 1999), fits cleanly into the existing air relief path, and is made of durable material to handle exposure to pool chemicals. It’s engineered for ease of installation—just swap out the old tube with minimal disassembly needed.

Pro Tip

Check the tube and associated connectors for cracks or wear when replacing; if the O-rings or fittings are degraded, replace them at the same time. Always ensure clean water during fill to avoid trapping debris in the air path, and lightly lubricate O-rings with proper pool-safe lubricant.

Installation Tips

Depressurize filter before working on the air relief system. Confirm manufacture date to ensure correct part-compatibility (post-Nov 1999). Handle fittings gently—plastic can crack if overtightened.
