Good point about it probably being too late, NancyM, hadn’t thought of that but makes perfect sense.
OP, for this winter, maybe invest in a water tank you can roll out to the barn and fill buckets from that? Then you can fill in the house. This 18-gal tank is meant for emptying RV waste tanks, but might be pretty useful for your purpose. http://www.campingworld.com/shopping/item/thetford-smarttote2-lx-4-wheel-portable-waste-tank-18-gallon/82131
There are adapters you can get to allow you to attach a hose to your kitchen faucet.
