I will post pics later. I just completed my first truly automatic poultry waterer. I started out semi-automatic with the poultry water nipple attached to a length of 3/4" PVC. This in turn was connected to a plastic pail. Each morning I would go out and fill up the pail because it would be empty. (I have a few ducks in the coop as well and they like to play with the water nipples) I just finished installing a toilet tank fill valve inside my bucket. Now I can adjust the water level so that the water doesn't heat up so badly. As long as I keep the hose in the shade, that is. I also installed a back-flow preventer so The water doesn't flow back into the hose when I shut off the water for anything. Just need to put some teflon tape around one of the fittings as it dribbles slowly. Also need to put some silicone around a couple of my water nipples. Now I am wondering if I can find some of the square PVC tubing I saw advertised online the other day. Either that or use some 1" PVC tubing instead of the 3/4". The nipples should fit better and less likely to leak. Also thinking of putting a PVC drip tray under the nipples since the ducks like to play with the nipples and keep the ground wet underneath. Not a problem so much in the 100* F, no rain since April weather we are experiencing here in TX. But that may end today. We are expecting a 30% chance of rain this evening.
