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.

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 dieCould 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 properlyWhen 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.
Hi, Recently my touch sensor stopped working even after inserting new batteries. It only now works with the handle. Please advice.

Will the faucet still work if the owner goes out?? We have ours hard-wired and don’t use the battery pack.
Asked by: Spud
Hello Jill,
Thank you for your question. The Delta Leland Touch2O Kitchen 9178T-SP-DST faucet is designed to only activate when touched. We recommend to turn the handle to the off position if leaving on vacation or for an extended period of time, but you can leave it on/open for day-to-day use.
Best regards,
Tanya

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

How to clean the sprayer?
We are having issues with the Leland series bathroom faucets and the aerator clogging up from our well water. You were so gracious to send the tool I was missing to remove the aerator on my 3 bathroom faucets so I can clean them out. All working like new again. So just to see the same tools works on this kitchen sink, removed and cleaned out much better water flow. My question is how do you clean out the sprayer part of the Pull Down faucet? Also on the spa tub Leland faucet the parts list does not show any way to take off the aerator to clean it, does it need a special tool like the others?
Asked by: Donna
Hi Donna,
Thank you for your question. You can clean the wand by unscrewing it from the hose to check the back. You can soak the head in a 50/50 white vinegar and water solution and flush backwards through it with water.
The high arc Leland Roman Tub Faucet T2775 uses the stream straightener, which takes a wrench tool, RP52593. The stream straightener on lower spout model T2778 will unscrew by hand.
Best regards,
Jon

We recently installed this faucet in a condominium. When the neighbors use their cold faucets, hot water crosses through our clients 9178T-SP-DST and hot water comes out the neighbors faucets.
Asked by: Bellevue Plumbing
Thank you for your question, Bellevue Plumbing! That is correct and this issue, also known as cross flow, will happen if the RP53468 Check Valves are not installed. We apologize for any inconvenience this may have caused and please feel free to contact us directly if you need further assistance.
