  • Prevent Water Siphoning Out of Aquarium
  • Rubber Valve For Longevity
  • Essential for Power Outages

A check valve is used to prevent water from siphoning out of your aquarium. If water siphons out it will usually damage the air pump, and lead to water on your floor. In extreme cases this can lead to fire if electronics are sitting in water.

Check valve

Works exactly as it should. Well-made check valve at a good price. I like that it’s clear so you can see if water is back-flowing in your air-lines.

Aquarium Co-op air tubing check valve

Works good! Installed it yesterday for a newly installed Nano tank. This tank is currently being cycled, just dialing in everything for this quarantine tank.
