Someone must have done this and have the answers for me. For archery elk camp this year we'll be camping out of our trucks at 12,000' right next to a stream. I think it would be handy to have a hose running from the stream to camp - say 50' or so down hill. I'll put a shut off valve at the bottom end. A) Will this work? B) What should I do with the end of the hose in the stream? C) Any trick to priming it?
