1) I have a kitchen faucet in my barn tack room. My tack room has hot and cold water. 2) I get one of these things in the link. 3) I remove the existing aerator on the existing faucet. 4) I hook up this coupler to the existing faucet. 5) I attached garden hose to the new coupler 6) I turn on the hot and cold water to a warm temperature 7) Run the hose out of the barn so I can bath my horse using the warm water or just get naked to take an outdoor shower (:>) 8) I have cold water right outside the barn to wash horses, but sometimes it is nice to have warm water to wash the horses. I am actually going to use it for a redneck outdoor shower at times.
