• Placement: It is recommended to keep the check valve as close to the top of the tank as possible.
• Compatibility: These are designed for standard aquarium airline tubing.
• Their primary purpose is to act as a one-way valve that prevents water from back-siphoning into your air pump, which can damage the pump or cause electrical hazards if the power fails.
