Loose faucet, fixable but annoying
928727
This is a classy looking faucet, but the top section works itself loose sometimes. It can be tightened, but it would be better if it were a single piece

Water pressure fluctuates as the valve is trying to adjust the temperature which sometimes gets annoying and takes away from "high-tech" automatic faucet setup.

I bought this two years ago to replace my old kitchen sink faucet. I honestly wanted a regular faucet with a separate sprayer, but those are "out of fashion"and are super hard to find. It works reasonably well for what it's supposed to be. However I can no longer hook up my fish take siphon to the sink, as it doesn't fit the fitting. When I got an adapter to fit it, it couldn't take the water pressure and shot out of the connector pieces, rendering my hook-up-to-the-sink-siphon useless. Which, when you have 3 tanks like me, makes it a little annoying because now I have to lug buckets back and forth.

And just yesterday I noticed that the button to switch back and forth between the "shower" feature and the regular spray is broken. It will not switch. Thankfully it stuck itself on shower mode, which I prefer. But the faucet is only two years old, and I rarely use the button to switch between the modes, so it should not be breaking already.

All in all, this faucet is great quality for the price. Herw are my two gripes: 1)The escutcheon plate is plastic 2) There is a weight you need to attach to the water line for the faucet head. There are two screws, one on each side to clamp down the weight to the water line. The front is threaded and for whatever reason, the back isn't. I can only assume that you're supposed to use magic or hopes and dreams to keep the weight together around the water line. Unfortunately, neither worked for me and I ended up having to filp it around and use the two  threaded sides to secure it on one side only. SIDE NOTE: The manual lists some obscure website's e-mail address as their customer support which I couldn't seem to reach. so... Try not to run into any problems because you're essentially on your own.

It's a very nice faucet, BUT.......
1. The faucet opens up easily for installing the water lines, but while no special tools are needed to install the lines, a skinny open end wrench does work a lot better than normal open end wrenches from the store.  Thankfully I already have one in the correct size, but feel it should be included in the kit.
2. The operation noise, is very present and can get annoying if not expecting it.  Turning down the amount of water pressure at the wall shut off valve does seem to manage it very well to almost a simple noise of water flowing.  Think of it like this.... When pouring water out of a bottle you get the sound of water flowing and that's expected.  The faucet, with the wall mounted water shut off valves fully open, produces a loud high pitched humming sound.  Closing down the water lines at the wall makes it bearable.

The faucet as a whole is a decent faucet,the hot and cold handles were crooked ,and no instructions as how to a just them

Faucet itself is holding up pretty well after about 6 months. The cable got a kink really fast though and it restricts flow when you try to use the sprayer :(

The faucet is installed, and looks just like the picture. I installed it myself (I'm handy with tools) and it was not difficult.

It seems to work well - no dripping or leaking, things shut off and on easily and cleanly.

My one detraction is that while the circular base is firmly clamped to the counter, the top portion seems loosely connected, so if one pushes lightly on the handle or spout, the entire vertical part will rock back some.  Looking under the counter, the copper pipes are rocking with the top, and one of them is rubbing against the through fitting in the counter, and I'm afraid that over the years that might cause a leak.  It also gives the impression that the faucet is not "sturdy" when the parts all seem to be quality parts. I have not yet contacted the manufacturer about it.

We replaced an old faucet with this one, and I feel that it may be giving less flow than our old faucet - which was also rated at 2.2 GMP - had a higher flow.  I don't know if this one is actually giving the rated amount, and the old one was giving more, however, since I haven't actually collected and measured the water.  My wife also feels that the water pressure is lower, and that the spray is not as forceful.

...

Two months later, the faucet has broken, is barely dripping when it is turned on.  We won't buy this as a replacement because the rocking issue makes it look and feel cheap.  We won't be giving this manufacturer a second chance.  Now I'll see if I can get a refund through the warrantee.

Nice to get away from the rusting metal caddies. however the area that sits over the shower spout could be sized correctly. the caddy slides off, I had to purchase a clamp to place in front of the spout area to ensure that it stays in place. Manufacturer should fix that flaw.

Changing all my fixtures to bronze, this faucet is beautiful and I love the way it looks on my stainless steel sink.  We had a slight leak in the faucet head switch, but one brief phone call with a very polite and friendly customer service representative had a new piece on it's way in no time.  Easy and perfect fix.  Faucet was easy to install, has strong water pressure, and good range.  On it's own, it gets 5 stars.

BUT, I can only give two stars (for appearance only) for the soap dispenser.  Read it was a problem, and it is.  It is an annoying nuisance as each time it is even barely used it drips soap into the sink leaving a constant puddle.  I'd take it out and do without, but there would be an ugly hole left.  So, once empty, I will discontinue to use it and it will just be a part of the decor.  Kind of disappointed as my old one never had this problem.  Maybe someday they will redesign it and send me a new one?  With their reputation as a dependable company, I'm surprised they haven't fixed the problem yet since it is a constant complaint from so many.  So just beware............if you buy it, it will drip.

Makes vibration sound sometimes when running at low flow. Hard to get bolt on tight enough when attaching to stainless steel sink. The hose is very hard to pull out (clicks into place which is nice, but whatever mechanism holds it in place requires a pretty good tug to pull it free) and the weight pulling it back in is too heavy so it is pretty hard to use one handed. To change the spray mode, the faucet has to be running (i.e. once water is turned off it switches back to regular mode). The hoses are pretty short and will not reach a supply at the bottom of the sink. Hoses are not marked hot/cold. Does not come with escutcheon/3-hole base plate... has to be ordered separately. Otherwise, the construction is very good though.

First, this review is actually for the chrome version of this faucet. I bought it a while back, and only installed it today.

The faucet itself is gorgeous. It's eye candy and very substantial. And if that's all I had to go on, I'd recommend it in a heartbeat.

My husband and I installed this faucet, and there were three major problems. First is the instruction booklet that comes with it. It absolute FAILS in the "body part" identification. There is no way to tell from the instructions which rubber washer goes where. That probably wouldn't be critical if they hadn't come off the drainpipe/pop-up assembly, but they did. We put them back as best we could and tried various order combinations, but the assembly leaks, so we'll be calling a plumber Monday.

Secondly, the pipe should come in two pieces (per their booklet). It didn't. It came in one piece and if there was a way to separate it, we couldn't find it. That's important because there should be teflon tape installed between the two pieces. There isn't. It leaks.

Third. The drain flange is almost impossible to get fitted tight enough not to leak. So yeah, it leaks.

Like I said, the faucet is gorgeous. I love it. But the entire pop-up/drain assembly is very flawed and the instruction booklet is next to useless (and nothing I could find on the Kingston Brass website was of help. If I were to do it all over again, I'd buy the faucet and leave the popup/drain pieces in the box and head to the home center to buy one.

This faucet is weird. It looks nice, but the handle sticks straight out, and I have to push it down to turn the water on, which always feels odd to me. I don't understand why it doesn't stand up when it's off, and push down (forward) to go on.
I use it with a Hansgrohe faucet, and it looks nice. The steel is nicely polished.
It was a total PITA to install with my RO filter, but eventually my plumber and I got it installed, and it works fine now.
The black rubber drain gets clogged on occasion and backs up onto my counter. No disasters yet, but that's a problem. My son heard it leaking, and I found a huge puddle on the floor, which I managed to clean up quickly, so no harm done.
When I go on vacation, I turn the water off under my sink so I don't come home to any watery surprises!
I gave it three stars because of the handle and the drain. I don't know if there's a way to design these faucets better, but those seem like design flaws to me.
Love having RO water, though, and it's nice to have an attractive faucet.

Love this insta-hot and cold faucet. Previously had used a PUR water dispenser in the fridge, but we all know how annoying that is to constantly refill. I purchased this in August 2014 and have used it on a daily basis.

Updating my previous review below. The handle leak stopped by itself. Lucky us? Maybe because we have hard-water? I have no idea, but it now works like it used to without any leaking what-so-ever. Added 2 stars from 2 stars to 4 stars.

-----------------------------
Only leaving 2 stars for the time being until the issue below is resolved.

We are almost done with a kitchen remodel and when the workers re-installed this faucet, the handle part now leaks. We've only had it for a year and 3 months so this is not supposed to happen. I assume that a gasket needs to be replaced, but According to InSinkErator Customer Service, this is not a serviceable part (even though there is a spot on the handle to use an allen wrench or something to take it apart). I haven't attempted to remove the handle because I didn't want to void any warranty.

Customer Service gave me the phone numbers of a few local/certified repair places. I set up an appointment for a service person to come out and look at the unit. If this is a manufacturer defect, the service company will bill InSinkErator directly for the fix. If it's MY issue, which I don't see how it possibly could be, I will need to pay $75 for the service guy to come out and give me a quote to fix the part.

This faucet comes with a 5 year warranty so I'm crossing my fingers that they can fix it. Until then, I will keep a rag under the leaky handle.

I like the looks, fit and finish of the faucet.

After 3 months of having the faucet, one evening my wife turned the handle and it popped off, upon further inspection the handles attach to a faucet shaft with an Allen key. The spot where the key makes contact with the stem of the handle was worn to the point where the Allen key no longer holds the shaft in place. While the part is only $12 to replace, its a pain to have to worry about it 3 months after purchasing. I'm waiting to see if Delta will replace the part for me since its 3 months old.

My old plastic splitter was getting old and I feared it would fail shortly, so I purchased this one. On the plus side it has a sturdy build and should last. The attachment to the faucet is with a collar, so the splitter can be positioned to make access to each valve easier. On the downside, the metal screw connections are not smartly made, so when I attached my hose it leaked no matter how tight I turned the hose. Back to the plus side, it has 3 rubber spare washers that came with the device, and adding one of them to the hose solved the leaking problem. Hopefully when I attach other hoses I won't have problems (at least not more than the number of provided washers).

Part of the problem appears to be that the connections (the silver colored things) have a flat spot on the side, requiring that the washers are both wide enough and thick enough to avoid the connection leaking. I wonder if including the 3 spare washers was an afterthought from others having the same leakage issues I did. I was going to return it, but since adding the provided washer appears to have solved the problem, Ill keep it and hopefully it will remain secure, as the faucet it is attached to is broken and cant be shut off itself.

Two stars subtracted for the odd design issue and fiddling required to get it to work right.

This is an attractive faucet, but...

I spent hours - installing, removing, and reinstalling - Trying to get the valve to mount correctly. The lower assembly of the valve section does not keep the valve body from rotating when the valve is operated. The soft washer on the bottom of the valve body became distorted, keeping the valve body cover from seating correctly. It settles out of place, making it difficult to stop the faucet from dripping. Not it will not seat at all and stays loose on the valve body. I removed it, replaced the washer with an O-ring, and tried again. That did not work either.

Also, the neck of the soap dispenser is very narrow, making it difficult to fill the bottle with soap without spilling.

I am returning this.
