PRODUCT FEATURES
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® 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 Love this faucet! This is one well built faucet! The Touch20 features may seem like a small thing, but it's already hard to imagine life without it. I found it much easier to install than I expected and it looks fantastic! To top it off, the pull down head I received was the wrong finish for the faucet, but Deltas customer service sent me a new one to match in record time. I couldn't be happier with the purchase and entire experience!

Rated 5 out of 5 by from Love the faucet ad touch function but have a question Love it, love it. When first installed water turned on and off immediately. For some reason now it turns on immediately, but turning off is delayed. By reading some reviews see there is software. Is there anything I should follow to upgrade the software or a sequence to restore the faucet to original on and off touch mode. Still loving it just need a little help.

Rated 4 out of 5 by from This product has great features but is not working properly My wife and I love the faucet with Touch 20 Technology that we have owned less than one year. Unfortunately, it no longer functions properly. We changed the battery pack and it worked well for a day or two but then stopped working. Again, I replaced the batteries and the unit does not work. I watched your installation movie and it appears that our plumber installed the unit correctly. Please let me know what I need to try to try to have the unit function properly. Your assistance will be appreciated. Chuck

Rated 4 out of 5 by from Love the Concept When we installed the faucet it didn't work. The water flow was a trickle only to be exceeded by the dripping when you turned it off using the touch feature. Needless to say I was disappointed. After calling Customer Service (which was excellent) a new solenoid was shipped. A week later I had the part and we installed it. It fixed the problem. I love the touch on and off feature. It's wonderful. The water flow still seems on the slower side to me compared to other faucets. Checking the water pressure to the faucet was one of the first things we did and that was good. I guess it's just something to get used to. I rated the faucet as Good and not Excellent because it's design is nothing exceptional but it is good quality and not excellent because I had to replace a part immediately. Performance, slow water flow. I would buy another Delta faucet because of the outstanding customer service. I just hope I don't have to call upon them too often.

Rated 2 out of 5 by from We love the touch technology but... We have had nothing but issues with this faucet since installing in February of this year. At first it kept turning on and off by itself and the light didn't work consistently. After two follow up visits from the plumbers it was determined the faucet needed to be replaced. After replacing it appeared the issues were corrected. However, this week it started turning on again by itself and the blue light, that indicates the water is cold, is no longer working at all. I have referred the issue to my builder but at this point I am thinking I may need another replacement faucet or a completely different faucet altogether.

Rated 2 out of 5 by from Faulty faucet At first it was great but within three months it worked sporadically. It starts and stops when it wants to and is driving me crazy. I loved it at first but for as much as it costs it's not worth the hassle.

Rated 1 out of 5 by from Defective, didn't work I purchased this product to replace a competitive product. After dismantle the old faucet to prepare for the instal we were excited to have a new faucet in place. Everything worked fine for about 2 minutes then the light stopped working, the touch still works but one of the main features is defective. Now I'm stuck, I can't just tear it out and return because I bought it online. My bad, I expected it to work.....

Rated 5 out of 5 by from Professional Review Being in the plumbing industry for over 15 years, It is a great faucet easy to install and maintain. The customer service from delta has always been great getting parts out to me and local representation in the LA area. For those who do buy a touch faucet and have a metal sink, ( stainless, cast iron, ect.) you must make sure that the shank does not touch any part of the sink insulate with something if you cant install with out it touching the metal. Otherwise the touch feature will short and will not work. I have one and installed one in my mothers house who's has a hard time with arthritis and work great. On hers i had to insulate the shank it kept touching the sink.

Rated 4 out of 5 by from Nice design, faulty electronics I realize we are in a world of electronics but here is my experience. We had our kitchen redone and this faucet installed as part of that three months ago. We love the faucet, its design and function. What happened two weeks ago was that the base LED started just displaying red only and would flicker out when going to cold. I called Delta and talked to a wonderful person who was very helpful, who diagnosed that the LED base went bad. He sent me a new base unit and the solenoid unit (at no charge) as he said there was a more recent software version. Yes, even our faucets get software updates. I am working with my original kitchen designer to see if they will come out to replace this for me so I can't say at this point if the issue is resolved. Just reporting where we are as of receiving an email to provide a rating today, 7-14-16.

Rated 5 out of 5 by from Nice faucet The sleek design and the need for only one hole drilled into my counter top was a big plus. The convenience of the touch on/off makes use in a busy kitchen a pleasure. good job Delta.

Rated 4 out of 5 by from Overall good but have had issues. Delta rep just left after replacing defective solenoid for the 2nd time in 9 months. Appreciate the warranty, but the 2nd solenoid failed and faucet was inoperable until I had to wrestle with bypassing the solenoid when we had house guests. The solenoid just installed only lights the LED indicator on hot water (red). The magenta light does not come on at all.

Rated 5 out of 5 by from Great faucet, and works well. My wife likes the touch on/off ability. Helps keep water dripping off your hands pooling up between the sink and back splash.

Rated 3 out of 5 by from Looks nice, not sold on worth the cost I would have rated this faucet at 5 stars when it was new, but 6 months later I just can't do it. The batteries only last a few months, then no water until replaced or disconnect the touch. The switch from stream to spray doesn't engage fully. So when we have it in spray mode, there is a constant, slight stream in the middle of the spray. We chose this faucet as part of a 75K kitchen remodel and we deliberately used high quality components throughout. We thought this would fit right in and last a very long time. When it works, it's great. My wife loves the touch functionality. But replacing batteries and fiddling with the spray switch constantly have soured me.

Rated 5 out of 5 by from Great for my utility sink My son encouraged me to buy this model. It is nice since I often have messy hands and the touch feature lets me turn on the faucet with little effort.

Rated 5 out of 5 by from 9178T-DST All, I would recommend this product to anyone who wants to enjoy a very attractive look to their kitchen. Extremely easy to install and the finished look has received a lot of positive comments from our friends. The touch feature is a great feature that allows easy use of your faucets. Very pleased with this product.

Rated 5 out of 5 by from Great faucet, great customer service This is a great faucet. The design/style is nice, and the function is fantastic. My family loves the touch feature; we've had it installed for about two months and we're not sure how we ever lived without it. It was definitely worth the extra $ for Touch 20. I did have an issue after installation: most of the time touching the faucet would not turn it of. The faucet responded, I would hear a click and the light would turn off, but water kept running. I called Delta the next day. I got straight through to a US based representative and in about 5 minutes had a new touch module in the mail. It was a great experience.

Rated 4 out of 5 by from Good functionand design We selected this faucet for our new house. The design is attractive, the finish looks durable, and it functions well. It has an easy switch between spray and stream. We are happy with the choice. After a few months it developed a drip on the side when in stream mode. I reported this to Delta and they sent a replacement.

Rated 4 out of 5 by from Its an awesome Faucet but the Battery usage is a big issue.... I love our new Delta Touch faucet and we are impressed with this new touch technology Butttttt the batter usage is scary. Six AA batteries did not last more than two weeks of minimal use. Is there any alternate to battery pack, please. Thanks

Rated 5 out of 5 by from Love this touch faucet! We remodeled our kitchen and when shopping for a new kitchen faucet the salesman recommended this one to us instead of a much more expensive model. We had our contractor install it for us and we love it! It is great when your hands have poultry on them or mixing meatloaf and you don't want to touch a handle with your hands. Love the 4 minute shut off also! It has been easy to clean too! The only issue we have had is if you reach behind the faucet and accidentally tap it the water will start and sometimes your arm is right under it!

I would recommend this faucet to any one in search of a new one. you'll love it

Q&A

When used as a bar/prep faucet for RO water can it be used with only a &ldquo;cold RO&rdquo; &nbsp;coming from the under sink RO system?&nbsp;

Asked by: Bobby
Hello! This model still requires the hot supply line to be connected to a shut-off valve, but yes it can be used for this purpose. Please reach out with further questions! Best Regards, Tim Digital Communications Specialist

Will the faucet still work if the owner goes out?? We have ours hard-wired and don&rsquo;t use the battery pack.&nbsp;

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

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

How to clean the sprayer?

We are having issues with the Leland series bathroom faucets and the aerator clogging up from our well water. You were so gracious to send the tool I was missing to remove the aerator on my 3 bathroom faucets so I can clean them out. All working like new again. So just to see the same tools works on this kitchen sink, removed and cleaned out much better water flow. My question is how do you clean out the sprayer part of the Pull Down faucet? Also on the spa tub Leland faucet the parts list does not show any way to take off the aerator to clean it, does it need a special tool like the others?
Asked by: Donna
Hi Donna, Thank you for your question. You can clean the wand by unscrewing it from the hose to check the back. You can soak the head in a 50/50 white vinegar and water solution and flush backwards through it with water. The high arc Leland Roman Tub Faucet T2775 uses the stream straightener, which takes a wrench tool, RP52593. The stream straightener on lower spout model T2778 will unscrew by hand. Best regards, Jon

We recently installed this faucet in a condominium. When the neighbors use their cold faucets, hot water crosses through our clients 9178T-SP-DST and hot water comes out the neighbors faucets.

Asked by: Bellevue Plumbing
Thank you for your question, Bellevue Plumbing! That is correct and this issue, also known as cross flow, will happen if the RP53468 Check Valves are not installed. We apologize for any inconvenience this may have caused and please feel free to contact us directly if you need further assistance. https://media.deltafaucet.com/PartsDiagram/DPD-K-9178T-DST%20Rev%20D.pdf Best regards, Edward
