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.

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.

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

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.

Q&A
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 this be installed with the handle on the left side?
Hi, Michelle1923!
Thank you for your question. We recommend installing this faucet with the handle on the right. You may install it with the handle on the left, but the temperature adjustment will be opposite of the standard operation for single handle faucets. You could compensate for this by swapping the hot and cold supply lines under the sink. However, the red/blue button on the handle will no longer indicate the correct temperature.
Best Regards, Antoine

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

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.

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?

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

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.

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).
