- 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.
looks strong , good quality
These are made by a few manufacturers. I’ve had others come apart, but the Aquarium Co-op ones have been solid so far.
It's a check valve! Does exactly what it's supposed to do and the clear plastic with black valve looks really sleek combined with the Aquarium Co-Op black air line tubing
Valve works as intended, keeps water from backing up into air pump if power is lost, must have!
