The GH-GOODS Return valve (Check valve) is available in 4 different colors and fits all standard 4/6 mm air and CO2 hoses.
The Return valve of GH-GOODS protects against returning water from the aquarium e.g. from a CO2 bubble counter or even on use of an air diaphragm pump with air stone.
The GH-GOODS Return valve is simply placed in the silicone hose of the air diaphragm pump or also on the non-pressurized side of the CO2 system (e.g. directly under a bubble counter).
If you look sideways on the Return or Check valve, you can see the membrane - this runs on one side pointed like an arrow. This tip indicates the flow direction. The end of the Check valve on which the membrane points (out), is connected to the hose in the direction of the aquarium, the other end (in) leads away from the aquarium.
