I thought some of you would be interested in this. I took a float valve from an old pressure washer supply tank and rigged it on my trough. The part is super cheap, so if the cows mess it up no big deal. Simple bul head fitting from tractor supply,couple pipe fittings, and the valve and your done. Here's a link to the part, and I have no affiliation.
