"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. *Industry standard is based on ASME A112.18.1 of 500,000 cycles.
