Check Valve

For use with all aquarium air pumps. Stops water from siphoning into your air pump in the event of electrical power failure or when removing filters from aquariums.

Checkvalve w/ Adjustable Air Control Knob

Lets you control the airflow from your pump. Helps prevent water from backing-up into your pump and reduces back pressure on pump diaphragms. Can be used in place of a separate air control valve.
