A Check Valve is a simple device used in airline tubing to prevent water running backwards down a air tube and flooding the room.
Often when beginners buy a air pump, tubing, airstone, etc. they negligent to fit a check valve.
When airpump is operating normally the air from airpump pushes water out of the tube and creates air bubbles in the aquarium. However if the tubing is detached from the air pump end or the air pump stopped working, air is forced out of the tubing by water pressure and if the end of the tube connected to the airpump is below the level of the airstone in the aquarium then a siphon action can occur and water ends up pouring out of tank.
The check valve only allows air to flow in the one direction and therefore prevents water getting too far down the tube. Check Valve is usually fit at the top of the aquarium.
