PRODUCT FEATURES
Delta® VoiceIQ® Technology pairs with your connected home device to give you exactly the amount of water you need with features like metered dispensing and custom container commands. Simply ask your faucet to dispense one cup, six ounces, a gallon or just about any other amount you could need. Custom container commands make everyday tasks easier, like filling a coffee pot or dog bowl, while thoughtful features like water warm-up and voice-activated on/off lend a hand when yours are full. Take command of your kitchen with a VoiceIQ® Faucet: a revolutionary kitchen faucet that thinks on demand. This Leland pull-down kitchen faucet is packed with functional features, like Delta Touch2O® Technology. 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 eliminates any possible surprises or discomfort. Kitchen sink faucets with Touch-Clean® Spray Holes allow you to easily wipe away calcium and lime build-up with the touch of a finger. 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® kitchen 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 sink 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 kitchen 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 MagnaTite failure, Delta customer service failure We have really enjoyed this faucet. The touch feature has been such a game changer. But like many others, the MagnaTite feature as rusted out and disintegrated. I have used Delta's online form, and emailed Delta customer service directly and have gotten zero response. As much as we like the faucet, Delta's poor customer service has ensured we will not buy any Delta product again.

Rated 5 out of 5 by from A quality kitchen faucet with great features I really love this Delta Leland Touch Single-Handle Pull-Down kitchen faucet. This faucet features a nice high arc with a pull-down sprayer that controls the water flow and spraying action well. The magnet docking station holds the pull-down sprayer in place and the whole faucet swivels easily between both of my double sinks. The internal parts are quality pieces with a diamond seal valve cartridge and an all brass body and handle. I love the traditional look of this faucet and the SpotShield Stainless finish is a dream come true for keeping it looking clean all of the time. Installation was easy for my husband who is my handyman.

Rated 5 out of 5 by from Awesome Features!! Best faucet ever!! I love the touchless feature!! I think that's the one thing we've used the most! It enables you to keep your cleanup area so much more sanitary and avoiding cross contamination. The pull-down sprayer is a close second for best features! The spray has very good pressure and range, and the arc and height of the faucet are fabulous! We have yet to figure out hooking up the wireless component, but I imagine that will be sensational and will only add to the overall impact and usability! I couldn't be more excited about a kitchen faucet!

Rated 5 out of 5 by from Best Faucet This is by far the best faucet I have ever owned. I love the fact it has a hands free option so when my hands are all full of stuff I am able to just touch anywhere on the faucet with any part of my arm and it automatically turns on. I also like how it has a sensor on the bottom that shows me the temperature of the water. This faucet is beyond cool as it can be set up to Alexa or Google mini. I currently had connected it to my Alexa and I am able to ask her to fill a cup or water or to turn my water on as well. I was not sure if I would ever really use any of these features but now I can not imagine not having them. I would absolutely recommend this faucet to anyone who cooks or who is looking for a new faucet to upgrade their current one as you will not be disappointed with this.

I have the Leland 9178-sp-dst kitchen faucet it is leaking at the handle-how do I correct

Asked by: John
Hello Valued Customer, Thanks so much for contacting Delta Faucet Company! It is possible that a flush could resolve this issue. To flush the supply line, first shut off the hot and cold-water supply. Remove the hot supply line from the shut-off valve and place the line into a bucket. Open the handle to the fully open middle position, and then turn the cold supply back on for one minute. The cold water should flow through the faucet and out the hot supply tube. Reconnect the supply line and repeat with the second line. If this does not help, please let us know. Please reach out with further questions! Best Regards, Kelley Digital Communications Specialist

I have a kitchen faucet, single handle and was a touch technology.ldont know the model,but it maybe approx 7years old. I need a cartridge for it.

Asked by: Pat1840
Hi Pat1840, Thank you for your question about the Delta Faucet model 9178TV-DST. Faucets with Diamond Seal Technology have integrated PEX supply lines and may include the RP50587 cartridge. Faucet models where the handle comes out of the faucet at a 90-degree angle would use a different cartridge. I recommend removing the handle and looking at the top of the cartridge to confirm. https://www.deltafaucet.com/parts/product/RP50587.html Please contact us directly if you have any additional questions! Best Regards, Bryan Digital Communications Specialist

can I clean the faucet with vinegar to remove scale or will that damage the finish?

Asked by: bak831
Dear bak831, Thank you for your question! I will be more than happy to help you! Straight white vinegar can eventually ruin the finish as it is acidic, however, if you mix a 50/50 mixture of white vinegar and water it will clean it right off after soaking for an hour or two. Feel free to contact us directly, if you need further assistance. Best regards, Kyra

I have a faucet that is clogged. Any ideas how to repair or parts diagram?

Asked by: Paul Legnard
Hi Paul, Thank you for contacting Delta Faucet Company! Please accept our sincere apology for the inconvenience you are experiencing. Here is the information needed to resolve your issue for you. Reduced flow is typically caused by debris. If only one side is affected, there is debris in the supply line. We recommend flushing the Delta Faucet Leland&reg; VoiceIQ&trade; Single Handle Pull-Down Faucet With Touch20&reg; Technology In Chrome MODEL#: 9178TV-DST supply line. To flush the supply line, first shut off the hot and cold water supply. Remove the hot supply line from the shut-off valve and place the line into a bucket. Open the handle to the middle position, fully open, then turn the cold supply back on for one minute. The cold water should flow through the faucet and out the hot supply tube. Reconnect the supply line and turn on both supplies. Check flow from the faucet. If this does not help, please let us know. Thank you for being a loyal Delta Faucet customer. We appreciate your business and look forward to continuing to serve you. Please contact us back with any further questions. Best Regards, Kelley
