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.

Rated 3 out of 5 by from Beautiful faucet, great idea, flawed product. I loved this faucet when we first got it. It was exactly what I was looking for in the kitchen, no more germ covered hands on the faucet and it was working great for the first two months. Then it started shutting off randomly. We replaced the batteries as needed and even with brand new batteries we are still having the issues. Turn the faucet on and it shuts right off. In the middle of washing a dish and the hot water shuts off. Washing your hands and the water turns off. VERY frustrating. Getting ready to disconnect the touch feature and just use it as a normal faucet...a very pricey normal faucet!!!!

Rated 4 out of 5 by from Love this faucet! We love this faucet! Didnt take long to get used to the convenience of the "touch" feature. Never have to turn the water on with messy hands, just touch faucet with your wrist or back of you hand. However, after being in our new house for less than a year, the touch feature stopped working out of nowhere;the solinoid had to be replaced. I spoke with Delta customer service and was sent the replacement part within a few days. Very easy fix, but and worried how long this one will last.

Rated 2 out of 5 by from Flaky features I really wanted to love this faucet, but it's had a lot of trouble. It looks great and the water pressure and touch-function is fine. It does seem to burn through batteries quickly, but I can live with that. I had it professionally installed, but after a few months the LED stopped working when the water was cold. Then a few weeks later it stopped when it was hot. I talked to Delta and we tried to troubleshoot it, but ultimately Delta replaced the solenoid. That unfortunately meant completely uninstalling the faucet, which I paid a plumber to do...again. A few months later the LED stopped working for cold water again. I decided to ignore it since it still warns when it's hot. But now the faucet takes forever to change temperature. I'll push the lever from cold to hot, and then need to pull it back and press it to hot a few times to get the temperature to change.

Rated 3 out of 5 by from One serious flaw This faucet was part of a total kitchen remodel. Almost immediately the water flow rate fell off to a near trickle. Cleaning the head restored the flow rate but it again quickly slowed to a trickle. Now we have to remove it and clean it twice a week or more. I know it's the head because we can remove it and get great flow from just the hose. Very disappointed Delta. I can get a Moan that won't clog up for a fraction of the price. And YES! The house has a whole house filtration system.

Rated 4 out of 5 by from Love my new faucet with longer reach I was looking for a faucet a little longer to save my back from leaning forward at my farm house sink. I love that it is touch activated but it is a little sensitive and sometimes it turns off by mistake. The only thing I would change is water pressure is much softer than my old one.

Rated 1 out of 5 by from Worked really nice for 60 Days Took a chance and bought this very expensive faucet about 90 days ago even though I read some of the customer reviews where people were complaining about the faucet turning on and off randomly when it was turned off. Initially I didn't have any issues but this particular problem started after about 60 days and I thought maybe I needed to change the batteries in the cabinet below but that didn't help one bit. I regret getting this because I feel it will turn on in the middle of the night or when I'm not home. So far I've gotten no answers from Delta but would appreciate some help.

Rated 1 out of 5 by from Doesn’t work The faucet frequently turns off mid use without touching it and it burns through batteries. When the battery dies the faucet is not able to be used at all, not just the touch feature.

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

What is the difference between Leland model #: 9178T-AR-DST and Model # 9178T SP-DST and the one at Lowe's Model # 9678T- DST? Also Can I order any Delta Kitchen faucet you make through Lowe's, or just select one's?

Asked by: MAUREEN
Thank you for your question, MAUREEN! 9178T-AR-DST and 9178T-SP-DST are the same faucet, but with different finishes. AR is a finish code for Arctic Stainless, and SP is the finish code for Spotshield Brushed Nickle. The 9678T-DST is the bar/prep version of the 9178T-DST. It has the same design as 9178T-DST, but has a shorter height. Certain retailers such as Lowes and Home Depot, have Delta products manufactured exclusively for those retailers. We can not guarantee if a specific retailer has an item in stock. If you need further assistance, feel free to contact us directly. Best Regards, Benjamin
