This is particularly helpful for areas with hard water. MagnaTite Docking: Delta's patented MagnaTite Docking Technology uses a powerful integrated magnet to securely hold your Delta kitchen faucet's pull-down spray in place when not in use. A light tug releases the wand for total flexibility and a full range of motion. When docking the wand after use, the MagnaTite Docking mechanism will guide the spray securely back into place. Diamond Seal: Delta DIAMOND Seal Technology utilizes a ceramic disc valve with a real diamond coating to produce a faucet that will last up to 5 million uses. That's an amazing 10 times the industry standard, guaranteeing a lifetime of leak-free, trouble-free performance.
