We own a mountain cabin in Chelan County, WA state. During the winter we drain all the hot and cold water lines before we leave to prevent frozen pipes. We've installed electric valves in the crawl space at the lowest point in the water lines to make the process easier/faster. But, we still need to open all the faucets in the cabin to allow gravity draining of the lines and this still takes several minutes to complete. My question is: Can we install Vacuum Relief Valves (e.g. http://www.cdivalve.com/products/detail/model-vr25-vr38-vr75-vr10) in some or all of the faucet supply lines in the house to allow automatic drainage?
