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. 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.

Rated 5 out of 5 by from Hands Free! Been waiting to add a hands free kitchen faucet for a long time. Now that we have remodeled the kitchen, I was able to add in the faucet I've wanted for some time. The styling and color (Venetian Bronze) are beautiful too!

Rated 3 out of 5 by from Would be 4 stars but... We love this faucet however it has a really poor design. Touch2O activates when I'm using the handle to adjust the temperature! When I went to adjust the temperature it turns off and then I have to tap it to turn back on, which sometimes does not happen the first tap. And since the water is turned off now I don't know what the temperature is and I have to Tap & Tap until the water comes on and then adjust temperature with the handle which might or might not turn off the water again since some genius thought it was a good idea to make the handle for adjusting temperature and water flow part of Touch2O. This happens constantly and is super annoying. The sprayer is not connected to this so... when I hold the sprayer it doesn't turn the water on and off why couldn't they have done the same thing for the handle for changing the temperature and water flow? It's ridiculous... look at the attached image to read the rest

Rated 1 out of 5 by from Didn't Work The electrical control box under the sink came from the factory with a short in it. You would hope that when it comes from the factory it would work.

Does the manual faucet work if the batteries die?

Asked by: Gaius
Hello Gaius! Thank you for your question. When the LED light blinks red on the Delta Dominic Pull-Down Kitchen 19940TZ-SPSD-DST faucet, it means that your batteries are getting low and need to be changed. If your light stays red and your water is off, then your valve will not allow water to run, until the batteries are replaced. If your light turns red while the water is running, the faucet will only work in a manual mode until the batteries are changed. Best regards, Tanya

What is the different between Delta 9178T-AR-DST and Delta 19940TZ-SPSD-DST ? I am debating which one to buy.

Asked by: Chinh
Hi, Chinh. Thank you for your question. The Delta 9178T-AR-DST faucet and the Delta 19940TZ-SPSD-DST faucet are of a different style design and have different finishes. The Delta 9178T-AR-DST faucet features our Arctic Stainless finish. The Delta 19940TZ-SPSD-DST faucet features our SpotShield Stainless finish and does include a soap dispenser. Best Regards, Rosanna
