  • 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.
