Touch it on. Touch it off. Whether you have two full hands or 10 messy fingers, Delta®Ttouch2o® Technology helps keep your faucet clean, even when your hands aren’t. A simple touch anywhere on the spout or handle with your wrist or forearm activates the flow of water at the temperature where your handle is set. The delta tempsense™ led light changes color to alert you to the water’s temperature and eliminate any possible surprises or discomfort. Delta® MagnaTite® docking uses a powerful integrated magnet to pull your faucet spray wand precisely into place and hold it there so it stays docked when not in use. Delta® faucets with Diamond™ Seal Technology perform like new for life with a patented design that reduces leak points, is less hassle to install, and lasts twice as long as the industry standard*. Kitchen faucets with Touch-Clean® spray holes allow you to easily wipe away calcium and lime build-up with the touch of a finger. You can install with confidence, knowing that Delta faucets are backed by our lifetime limited warranty. Electronic parts are backed by our 5-year electronic parts warranty. The industry standard is based on ASME a112.18.1 of 500,000 cycles.
