The Ritchie Pork King is designed to withstand the rugged nature of a pen full of swine. Built entirely of 304 stainless steel for maximum durability and long life, our Pork King fountains are also equipped with thermostatically controlled electric heat and the industry’s most reliable fast refill valve. A stainless steel flip lid provides extra protection to the water to keep debris from entering the trough. Easily maintain your Pork King waterer by removing the large top cover to access your valve and float.
