Rated 3.4 out of 5 by 158 reviewers.
Rated 5 out of 5 by Very nice product. We purchased this faucet as a replacement. The no touch technology is awesome and is really great for the grandkids since they do not need to touch anything when they wash their hands. They can simply waive their hand under the faucet -- it automatically turns off when they are drying their hands. It was a little tricky at first to get the hang of it but now it is second nature. May 21, 2013
Rated 1 out of 5 by This Faucet is Terrible This faucet is terrible. The touch and motion sensors go off randomly and cannot be adjusted! I bought this faucet because we just installed a similar Moen faucet in the kitchen which works flawlessly. Unfortunately Moen doesn't make a bathroom faucet with motion sensors. January 13, 2015
Rated 3 out of 5 by Fanastic faucet when it works. I love this faucet when it works, but it has stopped working twice in the year that I've had it because of defective solenoids. Delta customer service has been excellent in supplying the necessary repair parts in speedy fashion, but it is frustrating to be without a bathroom faucet for a week or two every six months. June 29, 2012
Rated 1 out of 5 by touch faucet design problem First the LED light for the sensor does not work. Delta is sending a replacement but I have to disassemble and install (again). Worse the design of the solenoid valve location interferes with the drain rod - rubs the plastic pipes and valve box. I cannot installed this rod (to the sink drain) because of the potential for a leak. You cannot move the box to either side without putting it in a bind. A touch drain for the sink doesn't work due to the tail piece is metal and interferes with the sensors. I you can live without a sink drain, you can use this faulty product. Also, Delta reps kept saying no manuf defect.---Right! January 15, 2014
Rated 1 out of 5 by Finish is deteriorating and pitting While I am quite happy with the function of the faucet, its exterior finish is pitting like a facial blemish. This is only 4 months after installation. A deciding factor in purchasing the Delta product, besides its technology, was its durability experienced with our kitchen faucet installed four years ago. Now I have go to trouble of contacting the company and paying again for the installation of a replacement January 16, 2015
Rated 5 out of 5 by Lahara Single Handle Touch2Oxt Bathroom Faucet Typical high quality Delta fixture. It was my first Touch installation. No issues at all with install. However, the fixture has cost me extra money. Two days after install, bride declares Kitchen fixtures must now be Touch activated. Sigh. February 6, 2014
Rated 4 out of 5 by Fun to use! This facet is fun to use and conserves water. The elongated spout makes bending over the sink a thing of the past. The facet was installed easily by a professional handyman. Easy to keep clean. April 10, 2012
Rated 5 out of 5 by Touch / motion works great Great looking. Touch turns on / off for about 60 seconds. Motion sensor turns on for about 5 seconds. Both work great. Kohler includes everything needed to hook up in box. March 28, 2013

Hi hil,

Thank you for your question! The EP73954 adapter will work with models manufactured after January 1, 2015.

If the faucet was manufactured before that, the EP74852 solenoid assembly would need to be purchased and installed first. You would then be able to use the A/C adapter.

Thanks,
Jon

Hi Wildhorse, Thank you for your question. The model 751T-PN-DST is equipped with our Touch2O.xt technology. This means that the faucet operates by touch and by proximity when you place your hands near the faucet. The proximity feature can be turned off leaving only a Touch2O faucet.

Answer: 
Hi Delta Fan, Thank you for your question. You can place the model 538T-RB-DST in manual mode by turning the faucet on and with the water running disconnect the battery pack. If the faucet is left on in the Touch mode it will only run for 1 minute with no activity before shutting itself off.

Answer: 
Hi Kev, Thank you for your question. The larger button on your model 9192T-AR-DST faucet toggles the water between the stream and spray settings. The smaller button boosts the flowrate from 1.5 gpm to 2.0 gpm in the stream mode.

Also make sure the wire is not pinched between the sink and mounting hardware. If you continue to have issues please contact our toll free Helpline at 1-800-345-3358 for further assistance.

What would cause a drop in water presssure on hot side only?

We have noticed a recent drop (50%) in pressure on the hot side. We pulled the connector to the cut-off and did not find any sediment particles clogging at that point. Are there any other internal filters to clean besides at the sprayer head?

Love the faucet, just a little irritated at the super low flow.

Answers

Answer: 
Hi Del, We are sorry that you are experiencing a problem with your model 9192T-RB-DST faucet. There is a debris screen in the solenoid valve that can be removed and cleaned. I have attached the a picture below that shows this process. Since the drop in pressure is only affecting the hot water you will want to verify that the 2 check valves supplied with the faucet are attached to your supply stops/shut off valves. You may also pull the RP50587 valve assembly/cartridge and make sure that it is clean and free from debris.
Thanks,
Dave
