A water dispenser for livestock, particularly pigs, having a connecting portion for connection to a water pipe and the like with the dispenser preferably being in a horizontal or slightly inclined position and having a mouthpiece to be activated by the animal, the mouthpiece projecting from a casing of the dispenser and being tippable relative to the casing axis. The dispenser has a normally closed valve which is spring loaded to a closed position and is movable by the rear of the mouthpiece for effecting unseating of the valve in amount corresponding to the displacing of the mouthpiece. The mouthpiece and a foot of the valve have discs of generally the same size with the pivoting of the mouthpiece being transmitted by its disc to the disc of the foot to activate the valve by the tilting mouthpiece.
