I have auto waters in the barn. I shut it off. I had a horse a few years ago colic & die due to dehydration because she wasn't drinking from the auto waters. I use buckets now, or 16 gallon tubs. Both of which come in heated varieties. I think, especially in a stall, it is important to monitor how much your horse is drinking, and you can't do that with auto waters.
That said.... I would love to set up an auto system for our tubs in the fields! Posted via Mobile Device
