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.

Rated 3 out of 5 by RJinPHX from Faucet dead when batteries die Could not believe my faucet would not work when batteries died!! I have wanted a touch to activate faucet for so long (I hate trying to turn on the faucet when I have raw meat on my hands). I was so excited after installing this, which, by the way, was pretty easy. Then to have it not work after only 2 months because the batteries died!! During my husband's birthday party! I was scrambling g to find more AA's wherever I could find them, and after only a month I cannot use my sink AGAIN. I am going to try the C batteries and fingers crossed it will last more than 2 months. I will repost if it does work, Delta needs to make this known

Rated 3 out of 5 by Jimmijic from Low water flow I like the features and the style but I am dissapointed in the low water flow that showed up just 2 1/2 months after an install by a professional plumber. Your help is welcomed.

Rated 1 out of 5 by Stirgo from Touch on/off system does not work properly When we received this faucet, the box was slightly damage on one corner. When I opened the box, there was a million very little metal balls loose in the box. In fact, the hose weight (plastic) was broken and half the balls were in the box. I had to use the metal, solid weight of the existing faucet I was replacing. The installation was really easy. The instructions are very clear and the provided wrench is very useful when you are under sink in a tight location. The pressure is good. The 3-function wand is nice and the magnet to keep it in place works well. The adjustment of the water temperature is not very progressive and it can be hard to find the right temperature between hot and cold. Now, here is the bad part that justifies the only one-star rating. This faucet has a mind of its own! The touch on/off function just does not work properly. The faucet goes on and off by itself without touching anything (i did not buy the touchless version). Only the non-rotating base of the faucet seems to turn on and off the faucet. A touch anywhere else (handle or spout) does not have any effect. The faucet can be on for 20 seconds then stop by itself for 3 seconds then turn on again for ten seconds then off a minute and turn on again (this is an example but it's all random). Also when pulling the wand down more than 3-4 inches, the faucet randomly turns off and then turns back on as soon as the wand moves upward. This is so ridiculous that I have disconnected the electrovalve and use it as a standard faucet. The problem is that I paid a high price for a faucet that does not do what it is supposed to. I DO NOT RECOMMEND THIS PRODUCT.

Rated 2 out of 5 by Lindy from Touch faucet can be a problem I bought this "touch" faucet, but you cannot just turn it on. You must touch it for it to come to life. So what happens when the battery for the solenoid is dead: it will not turn on, If you are using the adaptor plug and power goes out, I believe it will not turn on. That's what the people at Delta told me.

Rated 3 out of 5 by scottE from The Love doesn't last We love the touch feature, we live by it, and find ourselves tapping sinks everywhere we go that is not our kitchen. But, our faucet is 4 years now, and we had to essentially argue to get a replacement solenoid by year 3, and after another year it has gone out again.

Rated 1 out of 5 by Frustrated from What junk! The only reason this faucet got 1 star is because 0 stars wasn't available. I am so disappointed, angry, and frustrated with this faucet. I cook a lot and I was so excited to have this "touch on" feature. I have spent far more money on plumbers bills to fix this faucet (multiple times) than its purchase price. I had this installed about 5 years ago. First, about two years in, I had water leaking from the handle. To Delta's credit, they sent me a replacement part free of charge, but the bill for the plumber was on me. Shortly after that the light that senses water temperature failed. I bought a new solenoid (a nearly $200 part) and paid the plumber's bill to replace it. Unfortunately, that did not solve the light issue -- the sensing for cold water worked, but the red light never worked again. I decided to ignore the temperature sensing malfunction since the faucet worked without it. Now, another two years down the road, the solenoid has failed again -- the "touch on" feature, which was the only reason I bought this faucet, no longer works. I could've paid a whole lot less for a conventional faucet, but the "touch on" feature was important to me. Something else to note: with the touch feature not working, regular use of the handle every day, all day, loosens the screw in the handle which makes the handle loose and flop around. The handle screw needs to be tightened weekly. TLDR: Save money and aggravation and buy another faucet.

Rated 2 out of 5 by SandieD from Disappointing at every turn I took comfort in the Delta name and lifetime warranty 9 years ago when I purchased my very first fancy touch faucet. About 6 months ago, while cleaning, it started its decline and ultimately became inoperable. Delta sent 2 sets of parts but the more I tinkered with the worse it got. Finally I received a new unit which was supposed to be an upgrade. Definitely not. A contractor installed last night and the touch worked perfectly. Today we’ve had to touch it up to 4 times to turn the unit on. The sprayer is weird and does not give a normal spray. Who wants 2 side sprays? The splashless option is pretty useless. The faucet doesn’t pull out smoothly like my previous unit but maybe that will wear down over time. The “upgraded” version style isn’t as modern looking with its handle as my previous version. So I am disappointed but after having no working faucet for 7 days I was grateful to be able to cook and clean the kitchen again. I’d love to share my video but only a YouTube video link is permitted.

Q&A

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 with no batteries loaded in the holder?

Asked by: Alan

Hi, Alan! Thank you for your question. The Delta 9178T-AR-DST Faucet will fill not work without batteries in the battery case, unless the whole solenoid is removed so that the faucet can work manually. Best Regards, Rosanna

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

How does the aerator come apart for cleaning?

Asked by: Jill

Hi, Jill! Thank you for your question. The Delta 9178T-Ar-DST Faucet sprayer assembly does have a removable aerator that can be unscrewed counterclockwise from the face of the sprayer with the RP50815 aerator wrench. Once removed, the aerator, or even the whole sprayer can be soaked in a solution of 50% white vinegar and 50% water for an hour or even overnight to clean debris. Best Regards, Rosanna
