Aqua One Check Valve

Aqua One Airline Check Valve

A simple but essential piece of kit for any air-powered aquarium setup. The Aqua One Check Valve sits inline on your airline tubing and prevents water from back-siphoning into your air pump if the pump is positioned at or below the waterline — protecting your equipment from water damage.

Features & Benefits

• Prevents back-siphoning — protects your air pump from water damage
• Simple inline installation with a clear directional flow arrow
• Compatible with all Aqua One air pumps and standard airline tubing
• Suitable for airstones, sponge filters, ornaments and other air-driven equipment
• Suitable for coldwater, tropical and saltwater aquariums

How to Install

1. Cut your airline tubing where you want to install the valve.
2. Insert the valve inline, ensuring the arrow points toward the aquarium device (away from the pump).
3. Where possible, position the check valve above the waterline for maximum protection.
4. Test airflow before switching on equipment.
