The Oasis Thirst Quencher is easy for pets to use. A lick or nudge of the lever releases the water directly onto the dog's tongue, then shuts off automatically when the dog stops licking. Clean, sanitary and economical; ideal for home or kennel use. The Thirst Quencher has an internal valve design. The Thirst Quencher body is die cast with a hexagonal shape at its base to facilitate easy attachment and removal. The valve body is nickel plated for corrosion resistance and uses a machined aluminum lever. Shipping weight: 3/4 lb.
