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.

Leland (9178T-RB-DST) touch faucet. At first install (08/09/2021) the touch functionality worked as designed. I could touch anywhere on the faucet. As of 3 days ago, only touching the base of the faucet is working. I use battery pack and plug.
Can this faucet be used just as a manual faucet? Right now, I can’t get water if the batteries are dead. My faucet is 4 years old.

Thank you for your question about the Delta Faucet model 9678T-SP-DST LELAND® Single Handle Pull-Down Bar / Prep Faucet With Touch2O® Technology. I apologize for any difficulty finding this information. We are happy to help!
Yes, this faucet can be used manually.
One way is with the faucet running water, disconnect the battery pack by opening it. You now have a manually operated faucet. The solenoid was open allowing water to flow through and is now stuck open because you removed the power it would use to close. Reconnecting the battery would close the solenoid and make it electronic again.
Also as a second option, the solenoid assembly may be removed, and the wand hose connected directly to the valve outlet tube.
a. Open the battery holder cap.
b. Disconnect the sensor hook(s) from the spout and/or valve shank.
c. Remove the hose clip and hose from the solenoid.
d. Remove the solenoid from the valve outlet tube by removing the clip or swinging the clip open.
e. Reconnect the hose with the hose clip to the spout outlet nipple.
The faucet is now a manually operated pulldown.

The other day the cold water stopped working, almost like the valve does not open when we move the handle to cold. No recent maintenance on the plumbing system or other indicators of trouble. Faucet has been in operation for approximately 6 mo
Hello Bills79,
Thank you for contacting us, I would be happy to help you.
To flush the unit, we recommend the following:
Start with the easy stuff:
Remove your aerator, wand or hose to check the flow through the unit without that part installed.
If the flow is good, the piece you’ve removed is where the issue is.
Soaking the part in a 50/50 mixture of white vinegar and water could help remove any particles or debris blocking the flow.
If the water does not have a good flow, the problem could be in the faucet.
Next, check the supply lines for debris:
Turn the supply off to both the hot and cold-water lines.
Once off, turn the handle on the faucet to the on position and leave it there to bleed the lines of any excess water.
Next, disconnect the hot water supply line and place it inside of a bucket.
Once the line is securely positioned into the bucket, turn on the cold-water supply.
Please contact us back if you have any questions or need further assistance.

Nicole

Hi Doxie,
Thanks so much for contacting Delta Faucet Company about the 9178T-SP-DST!
I am sorry for the leak you are experiencing, at that location, we would recommend flushing the faucet and making sure the bonnet nut that holds the cartridge in the valve is tight. If the bonnet nut is tight, the cartridge would need replaced.
Please contact us directly if you have any questions or need additional assistance.
Best Regards,

The cap on the battery box will not clip on. How can I fix that?
Hi nancher,
Thank you for your question about the Delta Faucet model 9178TL-CZ-DST. Please accept our apology for the inconvenience you are experiencing. We are happy to help!
The battery box may need to be replaced. This is typically an issue with the tabs or arms of the battery box.
Please reach out for further assistance or with any additional questions!
Best Regards,
Bryan
