This hydrant is uphill from the barn, and there is a pole right near that hydrant. My thought is to run a piece of stainless steel cable from that pole to the barn. Then attach the hose to the cable with wire-ties.
The hose then runs into the barn, and to the stock tank. It will slope downhill all the way, so as soon as the tank is filled, I will remove the female hose end from the hydrant and the water inside the hose will drain into the tank, so the hose can not freeze.
However, I must make sure there are no sags in the hose, where water will collect and freeze.
The other problem I see, is that where the hose enters the barn wall, rain water will run down the outside of the hose and into the barn. I cant put a drip loop in the hose, because that spot would freeze in winter. I'm thinking I'll have to put some silicone caulk where it enters the wall.
Anyhow, I thought I'd ask if anyone on here has tried something like this? I am also thinking of using some other material, instead of a hose. I'm aware that a hose exposed to sunlight wont last real long, so I could also use that black polyurathane pipe that's made for underground use, or some of that PEX pipe. That Poly pipe is kind of stiff, so I dont know if I could get all the sags out of it. And being black, how well will that pipe hold up in sunlight?
So, what about that PEX pipe? How does that hold up in sunlight? I've never used it, but have felt it in stores, and it seems rather stiff also. I know it needs a special tool to attach fittings, and I will need to attach a fitting on the one end by the hydrant, so I can run a short hose from that pipe to the hydrant. I'm not too worried about needing that tool, because I can get the hardware store to clamp that fitting for a buck, before I hang the pipe.
Anyhow, what would be the best material to use? Poly pipe, PEX pipe, or just a garden hose?
