I already have a pressure regulator to use with the watering nipples, but i wonder if one is enough since the nipples require only 1 PSI and i need about 32 or so feet of pipeing which will include a 6-7 ft vertical rise. I'm thinking about building the waterer for the chickens with 6 nipples and kind of zig zagging the pipe so that i can have 2 nipples at a low height for bantams, 2 nipples at a normal height for large fowl chickens and ducks, and 2 nipples higher for the turkeys. I would mount this to the back of my rabbit shed which is part of the chicken yard and then run the pipe inside the shed, up the wall about 6 or so feet and then across the shed 20ft. I would then attach small water lines to the pipe over head and run them down to about 21 watering nipples that would be mounted to all of the rabbit cages. Does this sound like it would work well? Is one pressure regulator enough for that many nipples and length of pipeing? I don't have actual water lines going out to that part of my property yet so i use about 200 feet of hose connected to my house to fill up their water dishes and the rabbit water bottles. How could i stop the hoses and waterers from freezing without costing an arm and a leg? i've seen 200ft heated hoses but they are over $200. Any insight or advice will be greatly appreciated. I'm very tired of filling up water bottles every morning before work haha.
