PRODUCT FEATURES
The clean lines and geometric forms of the Dryden™ Collection, derived from style cues of the Art Deco period, offer a simple yet sophisticated design. Touch it on. Touch it off. Or go completely hands-free. Delta® Touch2O.xt® Technology helps keep your bathroom clean by giving you three ways to operate your faucet: manually with the handle, with a simple touch anywhere on the spout or handle, or by placing your hands near the faucet. The high-tech capacitance sensing capabilities of Touch2O.xt faucets allow the flow of water to be activated by breaking the capacitance field anywhere around the device, unlike traditional hands-free infrared sensors which require your hands be in a particular place and are sensitive to lighting conditions and clothing and skin color. Delta WaterSense® labeled faucets use at least 20% less water than the industry standard — helping you save water without compromising performance. You can install with confidence, knowing that this faucet is backed by Delta Faucet's Lifetime Limited Warranty on non-electronic parts and finishes and 5-Year Limited Warranty on electronic parts.
  • Operate hands-free by placing your hands near the faucet, with just a touch anywhere on the spout or handle, or manually using the handle
  • Helps keep your faucet cleaner, because washing the mess off your hands shouldn't involve making a mess of your faucet
  • Automatic water flow shut-off after two minutes helps conserve water
  • Integrated TempSense® LED light shows water temperature, changing from blue to magenta to red as temperature increases
  • Batteries last approximately 1 year if using AA batteries or 3 years if using C batteries, based on 20 minutes of usage per day
  • Optional A/C adapter EP102157 may be ordered separately
  • DIAMOND Seal® Technology is less hassle to install and helps your faucet perform like new for life, reducing leak points and lasting twice as long as the industry standard
  • Everything you need is together in one convenient box, including integrated InnoFlex® PEX supply lines
  • Fits 1 or 3-hole 4-inch installations (with included 6-inch deck plate)
  • Optional red/blue temperature indicator ring included
  • Metal push pop-up drain assembly in matching finish (included) is ADA compliant and simple to install, operate and clean
  • ADA Compliant
  • WaterSense® labeled faucet uses at least 20% less water than the industry standard without compromising performance
  • Rigid spout does not swivel
  • Backed by Delta Faucet's Lifetime Limited Warranty on non-electronic parts and finishes and 5-Year Limited Warranty on electronic parts

REVIEWS
Rated 3 out of 5 by from Nice design but iit doesn’t work I bought 2 of these couple of months ago because I have the delta handsfree kitchen faucet that works great. I thought these would be great in my bathroom, specially for kids. However, these faucets are turning on and off on its own when not in use. It also keeps going back to 1 minute timer even during use. It defeats the purpose of touchless when you have to keep tapping and more often than not, tapping doesn't work either. I isolated the wires to no avail. Love the design but products are either defective or need some quality redesign.It’s quite a disappointment and frustrating to use. I hope these can be replaced or return.

Rated 3 out of 5 by from Great piece of work-when it works. Have owned 4 (2 bathroom faucets and 2 kitchen faucets) with the 02 technology for approx 6 years. About every 2-2 1/2 years, each one has to have replacement parts, usually the sensor that turns the water on and off.

Rated 5 out of 5 by from Delta Touch less Faucet I love it! It especially great during this time of Corvid-19 ... touch less. So sleek on the counter. It keeps the counter around the faucet a lot cleaner than my prior faucet. I highly recommend it.

Rated 2 out of 5 by from FRUSTRATING I bought a house with remodeled bathrooms that have the touchless faucets and toilets. I think the folks that invented these must have stock in Duracell batteries!! I have replaced the batteries in my bathroom sink 2 times now and they are dead again...and we have only owned the house for 4 months!! The battery pack is a stinker to get to due to the type of cabinet that was installed...I have to remove the drawers (and everything in them before I do that!). I am too old to be crawling under sinks to do this....what a pain. HOW do i disconnect the the battery permanently???

Rated 5 out of 5 by from Great quality [This review was collected as part of a promotion.] This faucet is heavy duty and not like one you’d buy from menards/Lowe’s. Would definitely recommend!

Rated 5 out of 5 by from Incredible This faucet is incredibly solid with an elegant appearance and an amazing hands free technology. I put two in a clients master bathroom and everyone at the job was trying it! Way to go Delta!

Q&A

Should the unit turn on if I move the wires under the sink?

Asked by: JT
Hi JT, Thank you for your question. Some of the wires under the sink will be touch sensitive. We recommend isolating the wires from each other and any metal objects during installation. Best regards, Jon

Will there be any issues with the Touch2O.xt if this is installed in a copper sink?

Asked by: BathroomInstall
Hello Bathroominstall, Thank you for your question. The Delta Dryden Lavatory Touch2O 551T-SS-DST faucet can be installed on any type of sink. You would want to make sure that all insulator are used with the installation of the faucet and that the solenoid, battery box and wires are isolated from anything that can conduct electricity below the counter.

is it possible to turn off the hands free activation and just have the faucet as a touch on/off?

Asked by: Christina
Hi Christina, Thank you for your question. It is possible to turn off the proximity function on your model 551T-SS-DST faucet. If you would like to reactivate/de-activate the hands-free mode, please follow these instructions: 1) Tap the spout 6 times within 4 seconds. 2) the LED indicator light will flash red/blue. 3) Tap the spout an additional 6 times within 4 seconds of the flashing red/blue LED indicator light. 4) The LED indicator light will flash red/blue a second time to indicate the hands-free mode has been de-activated. 5) The tapping sequence can be done with the handle in the ON or OFF position. Thanks, Dave
