Pentair | 154689Z | Air-Tee Bleed Assembly | Pool Filter Air Release Valve

The Pentair 154689Z air-tee bleed assembly is a replacement air release component designed for pool and spa filtration systems. This assembly installs within the filter air relief plumbing to allow trapped air to vent safely from the filter tank during startup and operation. By releasing accumulated air, it helps maintain stable filtration pressure and supports efficient water circulation through the filter media.

Product Overview

The Pentair 154689Z air-tee bleed assembly is an essential part of the air relief system used in pool and spa sand filters. Installed within the filter’s internal plumbing, the tee assembly provides a pathway for trapped air to escape from the filter tank during startup and normal operation.

Removing trapped air is critical for maintaining proper filter pressure and ensuring consistent water flow through the filtration media. If air is allowed to accumulate inside the filter tank, it can reduce filtration efficiency and lead to irregular pressure readings. Replacing a worn or blocked air-tee bleed assembly helps restore proper air venting and supports reliable performance of the pool filtration system.
