Function:
When the oxygen pump is placed below the water level of the tank (such as on the bottom cabinet or table), when the oxygen pump stops working due to power failure or other reasons, it may cause the tank water to flow into the oxygen pump,to damage or burn out the oxygen pump, the check valve can solve this problem.
Tips:
1. It may reduce the air delivery capacity a little because of resistance, but not much.
2. If you receive the check valve and find that there is no air outlet after connection, please check whether the installation sequence is correct. If it is correct, please disassemble the check valve and gently pinch the vent with your hand.
