We always have to do that with early trips home. All I do on the last day's drive is open all the faucets and the low point drain. By the time we get home every drop of water has been vibrated out. Don't forget to drain the hot water tank.
This is why we have NOT left yet! Freezing temps and snow yesterday @ home:( We do plan to leave in a day or two. We have noticed more folks staying later this year due to the winter hanging on! Next year we are NOT going to leave at all!!!!! ๐
