Rated 4 out of 5 by from Great features I bought this faucet a couple of months ago. The installation was fairly straight forward. The only problem I had was that the faucet would randomly turn on/off for about 5 seconds several times per day. I contacted Delta and after sending several pictures of the installation and several back and forth emails, they sent me a new solenoid. I installed the new solenoid and the faucet so far has been working as it should.

Rated 5 out of 5 by from CLASSY FAUCET I just completed a powder room remodel and used this faucet on a granite counter top with white undermount oval sink. It looks great. I love the finish using the Champagne Gold and was able to match it close enough with a new light fixture. It is so easy to use with the touch control sensor control. I have had no problems with any of the features. I highly recommend.

Rated 1 out of 5 by from Awful finish!! We bought two of these faucets for our master bath and the matching faucet set for our Roman tub. We had the touch technology in our kitchen and it worked so well. The bathroom faucet that is used the most started to corrode within 6 months. I contacted Delta and they sent a replacement one. Six months later and we had the same problem. This time Delta offered one at half price. The other faucet was also corroding. I ordered the half price one and have waited until I can't stand the corrosion to replace it. The touch tech has worked well but the blue/red light stopped working on both faucets. I think the single lever is part of the problem. Not sure what to do next.

Rated 4 out of 5 by from NICE LOOKING FAUCET I LIKE THE LOOK OF THE FAUCET. IT IS WELL CONSTRUCTED OUT OF STURDY MATERIALS. THE FINISH WIPES DOWN EASILY. I THINK THE ONLY ISSUE THAT I HAVE IS WITH THE MOTION FEATURE TO WORK THE LEVER NEEDS TO BE UP. AND MOST PEOPLE JUST NATURALLY PLACE IT IN THE DOWN POSITION. I ORIGINALLY HAD THE VERSION WITH JUST THE TOUCH ON/OFF FEATURE (WHEN I THOUGHT I HAD ORDER THIS VERSION) AND AFTER TRADING OUT FOR THIS VERSION I THINK FOR THE PRICE DIFFERENCE I WOULD JUST HAVE STAYED WITH THE ONE WITHOUT THE MOTION FEATURE. THE TOUCH FEATURE ALSO REQUIRES THE LEVER TO BE IN THE UP POSITION. I THINK REALLY FOR THIS TO FULLY EFFECTIVE I WOULD HAVE LEFT THE LEVER OFF COMPLETELY. THAT WAY WHEN THE PERSON APPROACHES THE FAUCET EITHER THE MOTION OR TOUCH FEATURE WOULD TURN ON THE FAUCET.

Rated 2 out of 5 by from Still undecided Great features of both "touch and sensing" technology for turning on and off. My faucet has been installed for about 1 1/2 now and I'm beginning to experience some electronic issues with the "on/off" solenoids. The first issue is solenoid does not turn off when water temperature is running hot, by sense or touch. When I move the level over to cold for 10-15 seconds, the solenoid begins functioning again. Solenoid doesn't like hot. Second issue now is water mysteriously turns on and off. Blue light is flashing in series of two flashes. Next step will be a test of customer service. Will update later....

Rated 4 out of 5 by from problems with solonoid on 2 faucets Bought 2 of the Touch 20XT bath faucets and installed them. Instalation was very easy. One faucet the soloniod was bad and it dripped all the time. The 2nd faucet had problems with the sense function and would not turn on when placing hands under. Talked to customer support and they were great and sent me 2 new solinods. I installed them and the leak was fixed on the one, and the sense was fixed on the other. After about 2 weeks the sense stopped working again. I called Delta support and they had me check everything and decided the faucet had to be replaced. I'm waiting for the new replacement faucet. I like the faucet, it had the latest features. It was very easy to install. I worry about the reliability since I've had some problems. I've used Delta for a long time and they back up thier products, so I know they will take care of me.

Rated 1 out of 5 by from 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

Please explain the differences between Lahara faucet 15938t and 538t?

Asked by: Richard
Hi, Richard! Thank you for your question. The 538T-DST faucet is a Touch Proximity faucet that you're able to 'wave' your hand at the faucet to turn on and off the faucet. You can also touch the faucet to turn on as well! The 15938T-DST is a Touch faucet only. It does not have the Touch Proximity where you can 'wave' your hand at the faucet to turn on and off. Best Regards, Rosanna

Too sensitive?

My faucet turns on and off when I get anywhere near it. How can I turn off the no-touching mode to make it only respond to touch?
Asked by: SusanKC
Hi, SusanKC! Thank you for your question. There is a way to turn off the touch proximity setting. Here are the instructions: 1. Put the handle in the off position 2. Wait 5 seconds 3.Tap the spout 6 times within 4 seconds. 4. Notice the light flashes red & blue 5. As soon as the light stops flashing, tap the spout 6 times within 4 seconds. Prox mode is now off. To turn Prox mode on, follow the above steps. Best Regards, Rosanna

If this faucet it turned on manually and left on, will it turn off automatically, or just remain on indefinitally?

Asked by: SSgtGuy
Hi SSgtGuy, Thank you for your question! With the Touch2O feature on, the faucet will need to be activated by touch or proximity, and will automatically shut off after 2 minutes. In manual mode (power supply removed) the faucet will not automatically shut off. Best regards, Jon

Why is supplied pop up needed?

I'd rather not pull apart the plumbing under my sink. The installation manual says that the supplied pop up is required for proper function. Why?
Asked by: SK
Hi SK, Thank you for your question! The pop up assembly supplied with the faucet is manufactured to work with the touch faucet. Other pop ups may interfere with the touch technology. Best regards, Brandis

manual function

Can this faucet turn on manually. I am considering purchasing it for my mom's bathroom. She has Alzheimer's and I want to make sure she does not leave the faucet running all day.
Asked by: Delta fan
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. Thanks, Dave
