Abstract

An animal drinker allowing for the circulation of the water in the animal drinker. To this end, the animal drinker has two parallel pipe strings (23, 24) that form a water circuit ensuring a constant movement of water, namely that water flows continuously through the pipe strings (23, 24) even when no water has been removed at the drinking valves (20) over an extended period of time.
