A mechanical device in a pipe that permits the flow of water or air in one direction only.

A valve that closes to prevent backward flow of liquid

Limits the flow of gas to one direction only. Use a check valve between the bubbler and generator to prevent unwanted pressure build up in the generator, and a safety against a low level bubbler. A check valve, such as used on torches, is recommended.
