  • 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.

Quality Check Valve

This is a great check valve. The main component is high quality rubber and lasts a long time. I am slowly upgrading all my check valves with this product.

Peace of mind

We have just enough power outages to make this little device worth it. Peace of mind and easy to install just like on the video.

Great products

We absolutely love the spounge filter and all the accessories to go with it. We have three ten gallon aquariums all of which have their spounge filters.

it works

Great little airline check valve. It works and Aquarium Co Op sells them at a good price. Nicer than the typical ones that come packaged with air pumps. I occasionally add one of these to my order just to have extras on hand. Never know when you're gonna need one.

Works great

I have several of these now, and have yet to have one get brittle like lower quality ones.
