- 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.
Was high quality and works well.
What can I say? It’s a check valve that works great. I’ve got one on every sponge filter I’ve got .
Well designed check valve, makes it easy to spot in your setup and seems to have no issues with air flow!
Easy set up, and works great. Awesome experience and will continue to purchase through aquarium co-op
