A check valve is an essential accessory when installing an air pump for your aquarium. Due to gravity, water will always try to find its own level, which means that if your air pump is placed below the water level, you risk flooding in the event of a power failure.
The addition of an inexpensive one-way check valve can save you the trouble of flooding your aquarium. They are designed to allow flow in one direction only, so they will allow the pump to push air into the aquarium, but will not allow water to flow back from the aquarium to the pump.
