Rated 3.4 out of 5 by 154 reviewers.
Rated 2 out of 5 Three replacement cartridges in 8 months I had this faucet installed eight months ago and it leaked underneath the handle almost immediately. Delta sent a new cartridge and that seemed to do the trick for a while. But recently I have noticed leakage around the handle again and requested another cartridge. There seems to be a problem with quality control. Otherwise I like the faucet - the touch works great and it looks beautiful. But the leaking is a big problem. February 11, 2015
Rated 5 out of 5 by Delta Hands Free Dryden Faucet I purchased and installed this hands free faucet in my primary bath. Looks great and fairly straight forward install. A few little issues during install but reading the directions closely will help. The faucet can be touched on and off or you can place your hands under it and the electronic eye will turn on for about 20 seconds to allow easy washing of hands with no touch. Very sanitary from my perspective and the faucet works well. You can adjust the temperature with the handle and you also turn the water on/off with the handle. I had one occurrence where the faucet turned on by itself, don;t know the issue, happened once. When we leave for long time we shut the unit with the handle. In that case no water can be turned on in any case. Overall I like the look, I like the functionality and I think Delta did a great job with the overall design. Price was reasonable. Highly recommended. February 1, 2014
Rated 3 out of 5 by Compromised by an Expensive Non-functioning "Touch" Feature This review is of a Delta Faucet 9159T-AR-DST Trinsic Single Handle Pull-Down Kitchen Faucet Featuring Touch2O Technology, Arctic Stainless installed in March 2014. Even after a five hour installation attempt by a licensed plumber, carefully following the included instructions, avoiding any metal-to-metal or electric component overlap, and installing an under sink insulation barrier, plus a service call directly to DELTA seeking advice, we are still without the ability to use this faucet's touted "touch" feature. The problem appears to revolve around an inability to ground the solenoid electronics so that a touch activates the ON / OFF function. Our white-porcelain-over-cast-iron-sink set into a thick granite countertop complicated the installation process, necessitating the need to cut the hard plastic insulation piece to fit. When battery operated, the solenoid allows the water to turn on and off; however, the ability to operate the faucet by touch remains inoperable. Furthermore, the battery connection itself remains intermittent, easily interrupted whenever wires attached to the solenoid pack are jostled. These both appear to be design issues that need to be addressed. Until they are, if your installation involves anything but the most common kind of sink (preferably not made of metal), I would avoid spending the extra for the "touch" feature. If you do decide to go ahead anyway, find a plumber who has installed one with this feature before to assure your best chance for success. The faucet itself looks great; however, we have invested hundreds of dollars for a non-functioning feature and an unnecessarily complicated installation process that seriously mitigates our appreciation of its attractive design. March 22, 2014
Rated 3 out of 5 by Not worth the cost It's a faucet, it does what it is supposed to do. However for the money it is not worth it. 1. Does not swing far enough side to side. 2. Full of plastic. 3. The spigot does not stay in the housing very well. 4. The included water supply lines are not adequate, they are stiff plastic lines more suited to what you might find in a house with wheels not an expensive faucet. 5. Anything sets off the touch feature, dish towel touches etc.. I am very disappointed with the quality and craftsmanship of this faucet. Even more so that Delta deleted my first review of this faucet. March 9, 2013
Rated 1 out of 5 by Good in theory but not in reality. Overall poor design.... Worked fine at first, then thought the batteries needed replacing, it has been all downhill from there. Inconsistent functionality, the Touch2O rarely works properly, usually no water flow when turned on, have to pull the faucet head in and out to get the water to flow, sometimes cycles rapidly on and off, cannot leave in touch mode because will turn on and off on its own, very difficult to regulate the temperature, etc etc... Was installed by a plumber. Would never recommend the touch feature and have told others not to purchase. A faucet should not be so difficult to install/use this is why I feel the overall design is poor. October 17, 2014
Rated 2 out of 5 by Frustrating We bought and installed this about a year ago. For the first several months it worked perfectly...then the issues. Coming on by itself, not coming on when tapped, etc. Very disappointed with this product. We researched faucets forever and were convinced we made the right choice. After saving for twol years to re-do our kitchen and splurging for the touch control, I feel foolish and wish I stayed with a traditional faucet. As a military family, we've moved a lot and completed many renovations over the years and we've always used Delta products (faucets, etc) and this is the by far the worst experience we've had. November 4, 2013
Rated 4 out of 5 by Beautiful faucet, "touch" is a bothersome gimmick. The faucet is beautiful. The "touch" feature is just a bother. I never use it. I just use the faucet by turning on the water the usual way, however when I do that, the water keeps turning off. I paid a lot of extra money for this feature as it sounded like a good idea. I'm taking out the batteries and will just use the faucet without the "touch" feature. So - I would buy a Delta faucet again, just not with the gimmick of "touch". I have other Delta faucets in my house that have been there for 15 years and are still in great condition. It was very difficult to install. November 11, 2012
Rated 2 out of 5 by Inconsisentent performance The faucet looks great and worked fine for the first year. After changing the batteries, it has become possessed. It turns on by itself or shuts off abruptly when you need the water running. I contacted Delta and the customer service rep was helpful. The faucet then worked fine for about three weeks. Then it went back to its erratic behavior. I tried changing batteries, resetting, leaving unplugged for two days, changing the batteries again...nothing seems to work. July 21, 2014

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.

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.

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.

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
