The Airmax® PondAir™ Check Valves protects your aeration system by preventing water from traveling up through your air line and into internal aeration components. The Air Check Valve only allows a single direction of airflow; it is important that the check valve is installed with your aeration stone on the "out" end and the aeration source on the "in" end.
