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:
