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 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.

Rated 5 out of 5 by from Great look and features We're happy we chose this faucet for our new home 2 years ago. Delta's warranty is one of the best as they stand 100 percent behind their product.

Rated 5 out of 5 by from Very satisfied, thus far! After doing extensive research on a replacement kitchen faucet, I decided on this one from Delta. Initially, I was looking into a touch-free faucet which cost about $100 more, but decided against this after reading customer reviews that if the power went out the faucet would not operate. So, I decided to go with the Delta '9178T-AR-DST Touch2O' based on Delta's reputation, the faucet's features including the magnetic docking faucet head, diamond water seal, and touch on/off control. Before making my purchase, I also read many reviews from other buyers of this faucet to get their feedback on their experiences and any recommendations they shared. Three very helpful suggestions were to zip-tie the coupling clips to ensure they would not unintentionally pop off. Also, the use of an outer hose to fit over the faucet water line prior to flushing the faucet which would give better control of catching the rinse water into a bucket outside of the sink cabinet to keep it dry. Finally, purchasing the optional plug-in power supply adapter was recommended by several buyers who said that it made the responsiveness of the "touch on/off" feature of the faucet more consistently reliable without the need to fumble with replacing batteries. All these suggestions were quite helpful for me. As for the operation of the faucet that I installed about a month ago, I am very satisfied! The instruction manual and on-line Delta manufacturer's video helped prepare me for a straight-forward and clean installation. All of the faucet's features are working as advertised and expected. The weakest feature that I have experienced is the "shield spray" which is both weaker in operation than I would have preferred and must be held very close to whatever I am spraying to avoid splashing; otherwise, "shield spray" doesn't reduce splashing much more than the other operating spray functions do. I also wish that the plug-in solenoid power adapter was included with the faucet when you buy it rather than the battery pack feature as a matter of convenience, but I understand that not all purchasers of this faucet necessarily have an electric outlet located under their sink as I do and that the battery pack is their only option. Finally, the tubular specialty wrench that is included to secure the faucet to the counter top is a true blessing to have and made the 'trickiest' part of my installation so much easier. Time will tell whether or not the "Leland Touch2O" I purchased will live up to Delta's promises. At this point, I feel as though the quality of the product and its components will stand the test of time. Should I need future warranty assistance, I trust that Delta's customer service representatives and Delta will stand behind this product.

Rated 4 out of 5 by from Beautiful, Quality Made Faucet I've had this faucet about three months, and it's a beautiful and well made as I expected from Delta. Its only flaw is inconsistency in the touch feature. Most of the time it works as designed, but sometimes the touch feature does not respond, and other times it's way too sensitive. All members of our family have the same experience. At first I considered exchanging the faucet; but overall I like it well enough to put up with this one weakness.

Rated 5 out of 5 by from Great features Just installed this last week but I'm delighted with it. Love the dish spray feature and being able to pull the sprayer into the sink.

Rated 1 out of 5 by from Not What Was Expected We bought this faucet a month ago and unfortunately the shield spray feature that we paid about $100.00 extra for is simply not what is advertised or promoted. First, the water pressure with the entire faucet is much weaker than our previous faucet which makes it hard to wash food away. Because of that, the shield spray feature doesn't actually provide additional assistance to actually wash food away. Additionally, the 'shield' on the shield spray doesn't form a large circle as advertised. It may be a defect in our faucet but it still causes spraying.

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
