We always leave exterior valves, manifold and mainline drain valves, and testcocks in the open position. Then some folks turn it on themselves and don't realize that water coming out of the valves is because we left them that way. Then they expect us to come close everything back up for free.
Thats my main reason for not putting a draw off inside.
