Note:

Each air outlet needs to be connected, and the double-headed air pump needs two stop valves, and so on. It is recommended to buy to prevent the water in the hose of the oxygenation pump from flowing back to the machine and damaging the front-end air pump or other product equipment during power outages.Using tips:1. The use of stop valve will slightly reduce the amount of gas, because there is resistance, but the impact is not large.2. If you receive the stop valve and find that there is no air outlet after connecting it, please check whether the installation sequence is correct. If it is correct, please open the stop valve as shown in the picture below and gently pinch the vent with your hand
