| The selector valve allows you to easily switch between potable and rainwater. The valve itself is a simple garden hose spliter. Many are available in plastic, but I recommend spending a little more for a nice brass one. To integrate this splitter with standard 3/4" diameter garden hose threads into both supply lines requires several adapter fittings. The picture below illustrates the parts. |

| Connect the parts as shown above. Use ample amounts of Teflon tape to prevent leaks. You can buy a small roll of Teflon tape at any hardware store for a buck. Once hooked up, you can easily switch between domestic potable or rain barrel supply by switching both valves on the splitter. In the picture above, the valves are set to let the rain water flow in from the barrel. |
