I don't want to use nipples so I was wondering how it worked to use those cups and screw them into the bottom edge of a 5 gallon bucket? Kinda like this ( http://www.mcmurrayhatchery.com/poultry_cup_waterer.html ) but with the bucket instead of the pipe. We don't have a water supply near where the run will be (not one that can be hooked up all the time). OR we could use the bucket and hook the pipe up to it and then the cups on the pipe. Anyone have this type of system and can show pics?
