A gas feed system is disclosed for supplying a gas such as chlorine to a water system for chlorinating the water. The gas feed system includes multiple containers and provides for automatic switching over from one container to a second container once the first container is empty and such that the first container can be completely emptied. The invention also includes a gas feed regulator for controlling the supply of gas from a container such as a chlorine cylinder, the regulator having a simplified construction.
