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.

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.

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.

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: Cove

third question is related to LED light. It has never changed temps. It is always red?? Thanks for your help

Asked by: Joe P
Hi, Joe P! Thank you for your question, and I am sorry to hear that you are experiencing an issue with your Delta faucet. We recommend to reset the LED light wire and battery pack. To do this, disconnect the LED light wire from the solenoid. Disconnect the battery pack. Wait a full minute. While you are waiting a full minute, you can check batteries and see if they are in good condition, even try new batteries. Make sure they're all in the correct direction and tightly secured in the battery pack. After a full minute, reconnect the LED light wire into the solenoid and then reconnect the battery pack. Wait another full minute. After the full minute, you can then check your faucet and see if the blue light works better. If this does not, please contact our Delta Customer Service line at (800)345-3358. We are available Monday-Friday, 7am-7pm, CST and Saturday, 8am-5pm, CST. You may also email at customerservice@deltafaucet.com. Best Regards, Rosanna

Will the faucet work if the power goes out?? Ours is hardwired and we don’t use the battery pack. 

Asked by: Spud
Thank you for your question, Jill. We recommend connecting the battery pack as a backup. The faucet will not work by touch if the the power goes out and the batteries are not installed. You may use the battery box to turn the faucet on and the remove it to put it into manual mode. If you are unable to activate it by touch, you may also bypass the solenoid assembly completely by connecting the pull-out hose directly to the faucet. Best regards, Jon

What is wrong with a Delta Leland kitchen faucet with a RP50587 cartridge when you pull the handle straight down and it won't shut off? I have to push it up to the right and then pull down to cut off the water. This faucet when new has not worked right.

Asked by: Donald
Hi, Donald. Thank you for your question, and I am sorry to hear that you are experiencing a leak from your Delta faucet. We recommend to clean the bottom puck on the valve cartridge assembly and retighten the bonnet nut to stop the leak. To do this, turn the water off at your shut off valve. Remove the handle. Unscrew the bonnet nut. Pull the valve cartridge out and clean the bottom puck on the valve cartridge assembly. Reinstall the valve cartridge assembly and retighten the bonnet by turning clockwise, to the right. Install the handle back on and turn the water back on. Test the faucet. If the faucet still leaks, we recommend to replace the valve cartridge assembly, RP50587.

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
