Wuapu Water Dispenser is a must in order to take good care of your dog since it ensures its water supply. It includes a convenient valve for easy use of the dispenser: to refill the tank, unscrew the valve, fill the tank with water and screw it back; the tank can be easily controlled and managed because it does not drip. Thanks to the spring inside the valve, water will be dispensed gradually and automatically as your pet drinks and the water level drops.
