Check Valves



Simply Safe



Check valves are simple devices used in conjunction with airline tubing to prevent water running backwards down air tubing and flooding.
Many beginners when buying an air pump or tubing,airstones,etc will neglect to fit a check valve.
Experienced aquarists know the benefit and security of fitting a check valve because accidents unfortunately do happen!
