from over 3,000 reviews "If you operate an air pump on the aquarium for aeration and oxygenation of your aquarium inhabitants, you should place it so that it is higher than the water level. If this is not possible, it makes sense to install this check valve in the hose section.
This valve is only open in one direction and thus serves as a non-return valve: It prevents water from running into the pump and damaging it if it does not run at all - be it because of a power failure, a defect or simply because you only run the pump overnight, for example. This also prevents the aquarium from running dry via the air hose and keeps your bottom dry.
This check valve for air pumps has connections for a standard 4/6 mm air hose.
Install the check valve in the hose section as follows: The arrow on the clear part of the check valve indicates the direction of air flow, so it should point away from the air pump and toward the aquarium.
Connection: 4/6 mm air hose
