Float keeps trough filled automatically. Trough is deep enough for ducks/geese to get head into the fount. Works with pressurized water system. Float valve is protected by cover. This works great for ducks and geese! Trough length 29 1/2", drink height 5". 2 gal. capacity.
Far superior to bell waterers
We are very pleased with these trough waterers. They are far superior to the bell waterers. We especially love being able to hook them up directly to a hose. And they work great with our gravity feed water system.
