Here you go, the t-joint you see is super important because it allows the hose to drain completely in both directions. To the left is the hose we use to fill the heated waterers, and to the right is the hose going back to the house. There's another t-joint at the spigot to allow the water to drain from the hose. Then there's another t-joint in the basement that allows the water to drain out of the spigot into a bucket so that there's absolutely no water left in the system anywhere after it's turned off. He has the hose running on boards all the way back to the house so there aren't any dips. He had it tied to stakes at a slope, but just those tiny dips would allow the water to pool up and freeze. This is going to make the winter so much easier. We have 5 adult pigs that we breed and are expecting approximately 20 piglets in February, so it would be a lot of water to lug.
