This specially designed Check Valve will safeguard your air pump by preventing nutrient solution from back-siphoning and entering it in the event of a power outage.
Simply place the check valve in your air line tubing between your air pump and reservoir or hydroponic bucket, and you will never worry about solution returning down the air line and damaging your pump or causing floods.
