I have a drive-thru shop that will not be open this winter and we are winterizing the building, etc. but I'm not sure what I should do about the machines. Should I leave them hooked up and try to empty the boilers? Or blow out the lines? I live in the NW so it will get cold... if I just leave the water in the boilers when it freezes will it cause any damage?
