Single Handle Pull-Down Kitchen Faucet with Touch<sub>2</sub>O® and ShieldSpray® Technologies in Arctic Stainless

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® 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.

Unacceptably poor water flow.
Purchased 10/23. Started well but flow at the nozzle is barely more than a trickle now. I’ve cleaned and soaked the filter and nozzle head in a vinegar solution countless times but the flow just continues to decrease. It’s now unacceptable as a functional kitchen faucet. I’m in the market for a replacement.

Purchased and paid to install in July 2025.
Leaks from handle so they sent me a new cartridge but I need to pay some one to install. Crazy to believe a relatively expensive faucet would last less than 1 year.

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

Q&A
With model 9178T-AR-DST which finish, the Arctic Stainless or the Spot Shield Stainless would match better with GE profile stainless appliances?
The GE stainless has a hint of gold color in their stainless. Should we just try and match the stainless steel sink or the appliances?
Hi Mark,
Thank you for your question. Arctic Stainless features cooler metallic tones, with more blue in the color spectrum. Our SpotShield Stainless finish has a warmer tone.
Best regards,
Jon

Model 9178T-DST. I do not get enough water pressure on my kitchen faucet as it was before. Is any part that I should change or has to be clean inside some where taking it apart? Hope that someone can help me with this issue.
Hello Rick,
Thank you for your question. We would recommend flushing the supply lines of your faucet. To flush out the valve body, so that these parts do last as long as possible, please first turn off the water supply to the faucet. Gather an adjustable wrench, some towels and a bucket.
Disconnect the hot side Innoflex line. Move the handle to the full on position, middle temp.
Point the hot side Innoflex line into a bucket. Turn on the cold supply valve full.
Let a gallon or two flow into the bucket. Shut off cold supply.
Check bucket for debris. If no debris, empty bucket and run one more time.
Move handle to off position.
Reattach hot side line. Turn on both water supply valves.
Please feel free to call, email, or message us on social if there is anything else you need.
Best regards,
Tanya

My faucet has a low water flow. How do I increase the pressure?
Hi, Ken!
Thank you for your question. The faucet gives a 1.8 gpm. If you are getting less than a 1.8 gpm flow rate, we recommend to flush the line to make sure no debris is clogging the sprayer. You can also soak the sprayer in a solution of 50% white vinegar and 50% water mixture for an hour to clean. If you need any assistance with this, please call our Delta customer Service line at (800)345-3358. We are available Monday-Friday, 7am-7pm CST and Saturday, 8am-5pm, CST.

Is Leland®Single Handle Pull-Down Kitchen Faucet with Touch2O® Technology and ShieldSpray made of stainless steel material?
Hi, Hoa Le!
Thank you for your question. The 9178T-DST is made of metallic and non-metallic materials. It is not made of Stainless Steel material.

I have a pink blinking light and the faucet won't run. What's up?
I would try changing the batteries
Date published: 2024-03-28
My faucet is hard-wired, but we also have batteries in the battery pack for when our power goes out. My question is, are the batteries being used along with the other? Do I need to take them out and only use when the power is out?
Hi, Spud!
Thank you for your question. The Delta 9178T-SP-DST faucet only uses the back up batteries when the electricity is out and the A/C adapter is not being used. We recommend to keep the back up batteries in place.
Best Regards,
Rosanna

Can I leave my faucet in the “on” position all of the time or should I move it to off when I’m done in the kitchen?
Thank you for your question, Jill! A Delta Touch20 faucet can be left in the on position when not in use. In the event of an accidental activation, the faucet will shut off after 4 minuets.
Best regards, Edward

when will the Leland model be available with touch20 technology? At what price? At which distributors?

is the spray handle brass or plastic
Hi, Nicholas!
Thank you for your question. The Delta 9178T-SP-DST Faucet sprayer assembly is non-metallic. This helps prevent heat transfer that could result in scalding and reduce weight. Non-metallic parts are also beneficial in that they do not rust or corrode. Please know that all of our products are tested to ensure long-lasting use and have a Lifetime Limited Warranty.

Hi, if Leland sold on Amazon have ShieldSpray?
Thank you for your inquiry, Carole5! The Delta Leland Pull-Down Kitchen 9178T-SP-DST faucet is not designed with the ShieldSpray feature. The Delta Leland Pull-Down 19978Z-SS-DST faucet is the one with the ShieldSpray feature and it is a Home Depot exclusive model.

Typo in my last question. Here’s what I meant to ask. Does the faucet still work when the POWER goes out?? Ours is hard-wired and we don’t use the battery pack.
Hi, Jill!
Thank you for your question. The Delta 9178T-SP-DST will not work if the power goes out. We do recommend to keep your battery pack installed as a back up just in case the power does go out.

Rosanna

My faucet has auto shutoff after 4 minutes so how do I set to leave the faucet dripping when it gets cold to keep water from freezing
Hi Gina52,
Thank you for your question. We would recommend putting the Delta Leland Pull-Down Kitchen 9178T-DST faucet easily into the manual mode, by removing the lid of the battery box while the faucet is running. This will allow you to run water from the faucet, without the 4 minute shut off feature. For putting the faucet in manual mode permanently, please refer to page 17 of the maintenance and installation manual for your model.

Can the on/off control valve be left in the on position continuously and only control the water flow with the touch feature?
Hi, Aldie!
Thank you for your question. The handle assembly can be left in the 'on' position at all times. You will only have to use the handle to change the temperature and the water flow.

2 questions - Does the touch on/off work if the faucet handle is in the off position, the on position or both? If the handle is in the off position, at what temperature setting does the water come on?
Hi, Rishty!
Thank you for your question. The touch function for the Delta 9178T-RB-DST Faucet will only work with the handle in the 'on' position as this allows water to travel through the faucet.
Best Regards, Rosanna
Date published: 2024-03-28
If I use the adapter on this model 9178T-SP-DST, what happens should the electricity go out? Or am I missing the point, that this model also can function at all times as a manual non-touch faucet would, by using the hot-cold/water pressure handle?
Hi, Hulagma!
Thank you for your question. The touch function will not work in an electric outage when the A/C Adapter is in use for the Delta 9178T-SP-DST Faucet. We do recommend to keep the battery pack installed along with the A/C Adapter in case of an electrical outage.
Best Regards,
Rosanna

When the power goes off will the faucet switch to manual operation??? And when it comes back on, if the faucet is in the “on” position, will the 4 minute rule apply???
Hello Jill,
Thank you for your question. If you manually turn the faucet off, you would have to manually turn it back on. If the water is left running for 4 minutes with no interaction, it will automatically shut off (as a safety feature).

How long does the hose pull out? Wanting to use with a 42" sink.
It looks to be about 24 inches. I’ve never pulled it out all the way, it has a gray spray nozzle.

I hate the spray head on the faucet. 3 modes of spray and they are all puny. I had a Leland faucet that I got in 2007 in prior house. The spray was just 2 modes - regular or spray, Do you make a spray head like that that I could replace this one with?
Hello Kay42,
Thank you for your question about the Delta Faucet model 9178T-AR-DST LELAND® Single Handle Pull-Down Kitchen Faucet With Touch2O® And ShieldSpray® Technologies. I apologize for any difficulty finding this information. We are happy to help!
A replacement spray head without ShieldSpray technology is available as part number RP51480AR.
https://www.deltafaucet.com/parts/product/RP51480AR.html
I recommend soaking your spray head in 50/50 white vinegar and water to dissolve mineral deposits or common water debris that may be reducing the flow through the spray head.
Please reach out directly at customerservice@deltafaucet.com or 1-800-345-DELTA if you have any questions or need additional assistance. Thank you for being a loyal Delta Faucet customer.

Hello Blondie77!
