We got some watering nipples that just snap onto 3/4″ PVC pipe. We have a ball valve in the end that can be used to fill up other containers and this is feed from a IBC tote at the highest part of the property. We just have 1″ irrigation pipe laying on the ground to feed this and a short piece of regular hose to be more flexible and as a way to feed the PVC pipe. Doesn’t work in the winter, but for 9 months out of the year I know they always have at least access to a water source.
