Delta Faucet A/C Power Supply Adapter for Delta Touch Kitchen Sink Faucets with Touch2O Technology EP73954

Although it would be nice if this was sold with the faucet, it did what it was supposed to and supplied power. Make sure you have an outlet under your sink for this, your garbage disposal, and your dishwasher. If not, then you will have to contact an electrician to add one.

Works. No more batteries.

1) Works greatIn fact - the touch function is more sensitive and reliable now (to both turn on and turn off).2) A bit pricey for a Chinese product.But....3) I tried a cheaper generic product I found on Amazon specifically for this purpose, but it failed.4) Even at tens of cents per AA battery, you could potentially run for years before you spent the money these cost.5) See my pictures. The body of the adapters hang to the left (if you have standard outlet orientation with earth GND at bottom). I had a cabinet wall next to left side of my outlet so I had to flip my outlet vertically. No biggie.Now my technical guesses/comments for those who have insomnia.6) To be fair - these are AC to DC adapters. They are not marketed as noise filters. Filters require large capacitors which take up space. To be practical, these supplies can only be so large (like many other adapters on the market). This way they don't eat up the whole outlet face (and obscure a 2nd outlet). All the people complaining that these have problems with other equipment running should understand that. These likely have just enough capacitance to smooth out the ripple after the bridge rectifier, but may not clean up all noise kicked back from noisy motors or equipment on the same branch. If you suspect you have a noise issue, contact Delta for their advice on filtering. It's a fair question.7) Just a hunch, but my guess is that these perform better than batteries for two reasons. A) The voltage is always (relatively) the same (battery voltages drop after use. B) When the solenoid valve is energized the inrush current will also drop a battery voltage slightly (below 1.5V each). Not as much with a good adapter. I have not verified these ideas yet, but it's clear the adapters are so far outperforming the 3 years of battery performance I became accustomed to.8) Check your faucet age/version/instructions or check with Delta regarding if you can keep batteries installed in parallel (in case you lose power). That's how I'm running and it seems great so far.Good luck! I'm really happy with these so far.

Delta touch faucet technology is a work in progress. If you run into the "phantom touch" problem with it going off all by itself, or the battery devour problem where batteries last two weeks or less, or the "angry touch" problem where it won't turn on or off with regular touches but does turn on and off randomly - you may have landed here looking for a solution.Once you report any of the above problems to Delta, you need to be prepared for a journey into the Twilight Zone. You'll hear fantastic tales of exotic battery chemistry (are they really alkaline, silver oxide??? Try a different type....) and impossible requirements for wire positions that would confound a bomb technician (make sure no wire is within 6 inches of any other wire, yes I know you only have 4 inches of clearance under your kitchen cabinet) and conflicting requirements (yes I know the battery pack has a mounting hole in the back but it must be resting on the floor of the cabinet rather than mounted to the wall).You'll also be asked to perform photography which may require lighting, angles, and fields of view which would be difficult in a perfect laboratory environment - much less the bottom of your kitchen cabinet were you likely have less space to work than any other place in your home that requires regular maintenance.Almost like magic however, if you connect this A/C adapter (and they make certain to point out how important the ground wire is for this installation) all of the problems go away and it works great - for about a month. Oddly the old problems may return, and at that point you'll need a new kit that replaces the touch sensor and solonid.So why 5 stars with all the trouble? None of the craziness associated with the Delta touch faucets many of those of us who own them know so well arenthe fault of this A/C adapter. The part itself dutifully and faithfully converts 120V 60hz A/C into the DC voltage needed by the delta faucet. Also, it seems to solve the various "phantom" problems described above at least for some, for at lest a short amount of time.Good luck! Just keep in mind if you are buying this to try to fix your "phantom faucet" problems as the latest in a long line of exotic batteries and acrobatic wire positions and are hoping this is going to finally resolve it, the victory may be short lived....

So I can see why Delta didn't include this as some folks might not have an outlet under their sink. I was lucky that my contractor had put a two outlet socket for the dishwasher so this either nicely... except that the adapter cord was too short. I ended up having to put in an extension cord that was zip tied to the proper length so this could reach the faucet control.Seems a little expensive for a Delta branded adapter but it seems that they would know what specs will make their faucet work correctly and I was concerned that the cheaper Chinese knockoffs might be inferior to this one. So we went with this one... Time will tell if I overspent. Personally I think it's better visually than other cheaper units I've seen and it is grounded on the plug-end. Also, while we're at it, hour about you make the battery box on your faucets a plug-in unit instead of hard wiring it to the control box for the faucet, Delta? That's annoying. I've got this empty battery box sitting under my sink now taking up space. Stupid design decision. Boo.TLDR; you got an expensive Delta faucet, take the hit a get the Delta branded power plug it needs to work right.

This power supply is great in that you save money in the long run cuz you don’t need batteries. The one thing that is a hiccup is that Delta says not to plug it into a plug shared by a light. Not explained why. I had no choice in the matter, but found that in order for the faucet to perform correctly, the light switch would have to be turned on. I hope that’s all and that it isn’t a fire hazard.😳

I’ve had the delta faucet for 5 years now. I installed it with batteries as that was how it came. Good when batteries are fresh, spotty when batteries wear down. It still ships with the battery pack and I don’t know why. It should ship with the AC power supply and offer the battery pack as a backup. Batteries are a pain and they last between 5 - 10 months depending on use and quality. DON’T install with batteries alone.

Easy to install so long as you have an outlet that is not on a switch under (or quite close to) the sink.

Great product, works pretty good to my faucet
