Automatic Drain Valves: Water Automatic Drain Valve, Sprinkler Automatic Drain Valves
Our automatic drain valves are easy to install and help prevent damage to sprinkler systems due to freezing. They automatically drain irrigation pipes once water is shut off and the inner valve closes when water pressure is applied. These drain valves come with ½-inch or ¾-inch male threading to attach to various sizes of water sprinkler pipes. These little automatic valves are lifesavers and help ensure many years of dependable lawn or garden watering use without having to replace sprinkler pipes due to breaking or rupturing from freezing water. We recommend you put at least one auto drain valve at the low point of each sprinkler line running out from each irrigation valve.
