Touch on. Touch off. With Touch2O Technology, it doesn''t matter if you have two full hands or ten messy fingers. Tap anywhere on the spout or handle of the faucet with your hand, wrist, or forearm to start and stop the flow of water. Thoughtfully designed to make kitchen tasks easier, Touch2O Technology allows you to turn the faucet on and off with just a touch anywhere on the faucet''s spout or handle. Designed for precise, responsive control every time, no matter where you touch. You can easily control and change the water temperature above the deck using the faucet handle. TempSense Technology measures the water temperature in the faucet. The LED light at the base of the faucet changes from blue to magenta to red depending upon the temperature of the water to let you know when the water temperature is right for you. A/C adapter EP73954 is available to purchase separately as an option to avoid changing batteries. Even if the adapter is used, batteries are still recommended as a back-up if power goes out. Once power is restored, the solenoid valve will automatically revert back to using A/C power. All Touch2O models are water-efficient, underlining Delta''s commitment to conservation. The pull-down spray wand comes free with a gentle tug and gives you total flexibility. The hose extends and retracts without friction points, fed by gravity. As you raise the wand to dock it, the magnet embedded in the spout pulls the wand precisely into place. So, unlike other pull-downs that tend to droop over time, MagnaTite keeps your pull-down faucet looking picture-perfect. Delta''s exclusive DIAMOND Seal Technology uses a valve with a tough diamond coating. InnoFlex PEX waterways keep water inside the faucet out of contact with potential metal contaminants. This powerful combination brings you a faucet built to last up to five million uses. Only Delta faucets are equipped with Touch-Clean soft, rubber nubbins that allow you to easily wipe away calcium and lime build-up with the touch of a finger.
