Automatic Livestock Water Bowl Dispenser - 304 Stainless Steel Float Valve Waterer for Cows, Chickens, Sheep & Dogs - No Drain Hole/Hose - Perfect for Barns, Farms & Outdoor Animal Hydration

Depending on where you are putting it, you will most likely need some other parts to hook it into your system, but that is normal. I love the automatic waterers as I'm able to quicky give these a wipe every day and keep the water clean rather than a big barrel that only gets emptied every couple of days. I do tend to still keep a bucket around, just in case, something happens you've got that little extra supply to hold you over until you fix the problem.Put them out of direct sun to keep the water cool and less algae formation. The small amount of water can heat up to very hot in direct sun. I've made that mistake in the past. They'll last a good long time if you take care of them. The float valve comes apart and can be cleaned and replaced as needed. The biggest problem I usually have with this kind of system is the bolts used to mount it tend to start rusting and leaving residue in the dish. I should probably look into some stainless bolts, something that won't rust out over time.
