Airline Non-Return Valve 4mm

These check valves, also known as airline non-return valves, are absolutely necessary for an air pump system. These inexpensive and simple-to-install valves make sure that water cannot enter the air pump again (either through siphoning or gravity), shielding it from water damage. Each airline leading from the air pump to the pond needs to have one non-return valve installed.
