CrystalClear PondAir Replacement Check Valve (2 Pack) - 490316

The Airmax PondAir Check Valves protect your PondAir Aeration Kits by blocking water from entering your airline and internal system components. Check Valves allow a single direction of airflow.

Please note: that "in" and "out" markings are on either end of the Check Valves. Install the check valve with your aeration stone on the "out" end and the aeration source on the "in" end. Refer to the PondAir Aeration Kit video for instructions on installing the Check Valves.
