New in box. Product details 10-year Limited Warranty. Read about the terms in the Limited Warranty brochure. The cold-start function prevents hot water waste and saves energy. When you lift the lever straight up, only cold water is released. The function restricts opening the lever fully to the right. Hot water is released by turning the lever to the left. It is only then that hot water is consumed. This is a durable faucet that you can use for many years, since the hard, ceramic discs withstand the friction that always occurs when you change the temperature of the water. Chrome-plated brass is a hard and durable surface that is easy to clean. An aerator integrated in the faucet keeps the water flow just right while less water and energy is used.
