The bowl is empty when horse approaches because the water drains down slowly from the bowl. When the horses presses the paddle with his nose, the water rushes into the bowl…if they hold the paddle down the bowl can overflow but really by then, the horses’ nose would be submerged. Mine have never done that. Even while they drink, the water slow-drains out from bottom of bowl back down through the Bar Bar A and down into the ground. It works exactly like a frost free hydrant. I don’t have them inside. Mine is in the pasture with gravel and small rock around it as a little “pad”. When my craziest horse is really thirsty he’ll press the paddle, drink, press, drink. Sometimes I hear him press it a few times but I’ve never seen mine overflow and it’s close to the barn so I see/hear it in use. I’m not sure if they have a different version for stalls?[/QUOTE]
Interesting.
The ones we had were a bowl with a paddle, it didn’t drain anywhere, we cleaned them every day, but had to shut them off for some horses and go back to buckets, because they would play and keep them running over.
Right now, we prefer the 6’+ water troughs between runs and in pastures.
Some have drains and are easier to clean, the others we pump them out to clean them.
We have “bird ladders” in all of those, so there are no dead critters in there, they can get out, but they don’t stay very clean, not like the kind that don’t hold water or very little and gets cleaned daily.
Then, horses tend to drink out of puddles on the ground …
The reason for the larger troughs, they always have water, they can drink and dunk to their pleasure and if the well would quit, there are days of reserve left there in a pinch.
Since we freeze hard in some of the winter, we are wondering about the Cobbett waterers, that use ground heat to stay open in the coldest weather and seem to at least hold a good supply and be easier to clean than our big troughs.
I am afraid of horses not having water with a very small bowl or on demand only if something happen and no one is there to see they are not getting water for any length of time.
