Why Air Vents Matter:
Trapped air in irrigation pipelines causes reduced flow, pressure surges (water hammer), inaccurate flow meter readings, and potential pipe damage. Install air vents at all high points in your mainline and at the end of lateral runs to ensure efficient, reliable system operation.
