- 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.
I replaced a check valve that worked but had a high resistance with this valve. So hard it was a guess as to which direction it worked.
This check valve is much better.
This was in my first order from Aquarium Co-Op and I have ordered more for the rest of my tanks.

This is a very sturdy and effective check valve. Much better than the one from my LFS which was flimsy and broke as I installed it! And for which I paid $6.29!
