The unique integrated pull-down wand feature lends the Trinsic Pro kitchen faucet collection its characteristic style as well as unrivaled functionality. The Trinsic Pro faucet puts control in the hands of the user with the flexible, spring-design undocking spout, which can be easily disconnected then magnetically re-docked for free range of motion. When docked, the Trinsic Pro faucet still operates as a true pull-down faucet with MagnaTite Docking. 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. 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.
