For outdoor hoses, what you're supposed to do is leave the valve outside the house fully open (with no hose connected to it), but close the last valve inside the house leading to the hose line, while it's above freezing in the fall - in this way the water in that section of the line should drain somewhat leaving the line not completely full, such that if it freezes in the winter, there's no impact.Should I open up the valves to my 2 hoses? I always shut them off for the winter, one is near the back or the house and the other is near the front of the house. I also turn the lever's to the off position - not sure why I do this, imagine someone told me to once we bought the house
