Touch it on. Touch it off. Whether you have two full hands or 10 messy fingers, Delta® Touch2O® Technology helps keep your faucet clean, even when your hands aren’t. A simple touch anywhere on the spout or handle with your wrist or forearm activates the flow of water at the temperature where your handle is set. The Delta TempSense™ LED light changes color to alert you to the water’s temperature and eliminate any possible surprises or discomfort. 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® ShieldSpray® Technology cleans with laser-like precision while containing mess and splatter. A concentrated jet powers away stubborn messes while an innovative shield of water contains splatter and clears off the mess, so you can spend less time soaking, scrubbing and shirt swapping. Delta® faucets with DIAMOND™ Seal Technology perform like new for life with a patented design which 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. Electronic parts are backed by our 5-year electronic parts warranty. *Industry standard is based on ASME A112.18.1 of 500,000 cycles.

Rated 5 out of 5 by from Outstanding Products and fantastic customer servic I bought a faucet about 6 or 7 weeks ago and got busy and couldn't get it put in right away so I didn't know how good or bad the product was going to be at time of installation. This is a great product and works beyond my expectations. I did have a issue with a solenoid and Delta sent a replacement out without question. Unbelievable customer service, I identify the problem and have the replacement parts here within days.

Rated 5 out of 5 by from Convenient! Beautiful! I love this faucet! Touch anywhere on the neck or the lever and the water goes on and off. The sprayer head does not turn it on or off, which is wonderful. I got the spotless version and it is! I have been using it for a couple of weeks and I have not had to "clean" it or wipe it down for prints or water stains and we have hard water. I would highly recommend this faucet. We bought the cord separately to plug it in to the outlet instead of thinking about replacing batteries. We had the electrician add more outlets under the sink to be able to use it this way.

The touch on works with battery but it won't work with A.C. power supply. Why?

Asked by: Spectrum
Hello Spectrum, Thank you for your question. We actually recommend you leave the batteries in the battery box while using the AC power adapter. It is recommended to keep it plug up due to the fact, if there is not enough power it will not work. Best regards, Tanya

Artic or Stainless

We are looking at getting the Leland Touch 20 in the Artic finish, as I like the brushed look for our new kitchen addition. Will this go with stainless sinks?
Asked by: rbrad11
Hi rbrad11, Thank you for your question. The Arctic Stainless is a brushed finish that should match most stainless appliances or sinks. Arctic Stainless is lighter than our Stainless Steel. Arctic Stainless faucet should go with most stainless sinks, but may match exactly. Thanks, Jon

We have a nickel coated sink. What color would be match?

Asked by: Steve
Hi Steve, Thank you for your question. Arctic Stainless and Stainless Steel are both brushed finishes. Over the years, the color of stainless steel used on appliances and sinks has migrated from warmer tones, with more red in the color spectrum, to lighter tones where blue is more predominant. Arctic Stainless features cooler metallic tones, following a trend seen throughout the kitchen. We recommend comparing the finishes at a store near you to determine the best match. Best regards, Jon

Will the faucet still work if the owner goes out?? We have ours hard-wired and don’t use the battery pack. 

Asked by: Spud
Hello Jill, Thank you for your question. The Delta Leland Touch2O Kitchen 9178T-SP-DST faucet is designed to only activate when touched. We recommend to turn the handle to the off position if leaving on vacation or for an extended period of time, but you can leave it on/open for day-to-day use. Best regards, Tanya
