A toggle on a Multi-Flow™ wand increases the stream from the standard 1.5GPM to a higher flow to more quickly fill the sink as well as pots, vases, or other large containers. Toggle back to 1.5 GPM for normal, everyday use. The innovative Multi-Flow feature can be found on a variety of Delta kitchen faucets. 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. The included escutcheon completes the ensemble for a more finished look.
