I have Four(4) different Zerowater Products. Two(2) Pitchers and a Five(5) Gallon Dispenser along with a smaller Dispenser as well. The Customer Service within Zerowater Co. has always been very Cordial and very Nice and Professional to Deal with. The Ladies and Management in Customer Service listen to the issues and always Treat Customers with Respect and Respond in Kind with any questions or issues I have experienced. Top Notch Company all the way around...that is why I stay a Customer of Zerowater. Their Products are Great!
