Rated 4 out of 5 by from Delta Foundation two handle Kitchen Faucet Looks nice on out stainless sink. The only negative is the low flow water and hot water. Have to let the water run a long time before the water is hot. My old faucet did not have a water limiter and it did not take long for the hot water to reach the sink.

Rated 5 out of 5 by from Nice looking, easy to install and works! The other day, I was under my sink to get a cleaning bottle out and found my sink was leaking. New sink, new faucet. Went to the two handle with sprayer. Looked nice and works great, not to mention easy to install. Would recommend.

Rated 5 out of 5 by from Faucet has great features With Deltas long history of superior products and reliability wouldn’t purchase anything else. Specifically on the kitchen faucet i purchased it has a clean and sleek look as well as smooth action on the way the handles operate. Cant go wrong with purchasing any and all types of delta products.

Rated 5 out of 5 by from Love the style of this faucet! So pleased with the feel and look of this Delta faucet. The handles turn easily and feel very stable on the base (not true with other brands I have bought). Love the faucet, love the price, love the quality but most of all I commend Delta for their excellent customer service. Having contacted them with a minor issue I found they responded within 24 hours and did quality follow-up to resolve my issue. Delta truly stands behind their products with pride and the customer service to prove they care about both product and customer.

Rated 1 out of 5 by from Already failing after three weeks... We had two of these faucets professionally installed about three weeks ago and the stainless one in the kitchen is already failing. The faucet is sticking and difficult to rotate, the handles flex like cheap plastic, and the hot handle squeaks and doesn't move easily. Very disappointing.
Date published: 2017-09-24
Rated 3 out of 5 by from I would rate this kitchen faucet 3.5 star The faucet was easy to install and it is a nice looking updated kitchen faucet. The only thing I am concerned about is the faucet handles which seem to flex when you turn them on and off.(they are not sturdy)
Date published: 2017-08-27
Rated 3 out of 5 by from Looks good My only complaint is the faucet itself. I like the higher faucet but I don't like the way it feels loose. I had a second plumber look at installation thinking that the first plumber had not installed it correctly. It was installed correctly but was told it is a "2 piece" faucet head instead of one piece and it feel loose when you move it to the left or right. I wish I knew there was a difference when I bought this one. Otherwise, new faucet looks great.

Rated 5 out of 5 by from I have always purchased Delta for quality, product durability and style. I especially like the look of the one I just purchased. Great sleek look, quality and dependability is why I keep buying Delta products.

Rated 5 out of 5 by from So far, so good. Previous version, of a similar Delta unit, leaked & this is the replacement. About two and a half years ago, I purchased a Delta two-handle kitchen faucet with spray. Four weeks ago, it began to leak just below the Hot knob, whenever either handle was turned on. I did not have any purchase receipts or documentation of where & when I bought it ... and I didn't want to deal with trying to repair it myself. Plus, there was a potential that the leak would get much worse - possibly doing damage to my kitchen, so I decided to purchase this new unit. It is the exact design that fits my needs. Installation was straight-forward & directions were clear. So far, so good.

Rated 5 out of 5 by from A great product and affordable also. This faucet is exactly what we needed for our kitchen sink. It is high enough to be able to wash large pots with ease. We're very satisfied with the color and maintenance and the price was affordable also!

Rated 3 out of 5 by from Nice looking faucet set, but mine had problems.ad they done that I would not have had the first problem. It looks great, love the high sweeping arch of the faucet, but the sprayer is problematic. The only way for a consumer to test any faucet is to install the whole device and turn it on. (The factory cpuld test each part in a test setup.) At which point you find out what is bad, and I did. The sprayer leaked from the head to flexible hose fitting. Took it apart three times looking for the problem and could not find it. I called customer support and they sent out a complete assembly, which arrived in about 5 days. Now I had to climb under the sink and reach all the way up to disconnect the hose to replace it, while maneuvering around all the plumbing in a double basin sink. I first studied the diagram, looked at the part -- they did not match. Looked for instructions on how to disconnect the hose from the faucet, but none were to be found. BTW, it is squeeze the the very top of the fitting on the two tabs which move about .05" inwards and it will release. Next installed the new one and hooray, no leak. But the design is such that it captures water behind the spray nozzle and slowly leaks out from behind the spay nozzle face after you place back in the holder. All in all, it is a reasonable priced, slightly flawed faucet.

Rated 5 out of 5 by from Love the product I absolutely love my faucet. Goes really well with my new vanity.

Rated 5 out of 5 by from Product filled a special requirement I have a shop that I spend my retirement time in. I have a clean-up (kitchen style) sink and the single lever faucet failed. It was so old parts were not readily available and I needed a special tool to remove the cartridge. Also I wanted the raised high nozzle The new Delta filled the bill completely.

Rated 5 out of 5 by from This is a wonderful faucet! My new Delta kitchen faucet has a good appearance, the hot and cold water handles move smoothly, and the spout moves smoothly, the aerator works well because the water comes out soft and gentle! It was easy to install!
Date published: 2017-03-24
Rated 4 out of 5 by from excellent customer service just would like to get the review problem solved having a problem with the aerator causing the diverter to make noise when turning on hot or cold faucet. With the aerator out it is fine.

What kind of adapter would I need to attach a portable dishwasher hose? it's to small for the tip and when I unscrew it it's too big. can't seem to find the right size. Any help is appreciated

Asked by: theopholismmviii
Hello, Theopholismmviii! Thank you for your question. The Delta Foundations Kitchen 21988LF-SS faucet has an aerator with a thread size of 55/64"-27. You will need to talk to your local retailer or wholesaler about getting an adapter that fits your portable dishwasher to also fit the faucet thread size. We do not manufacture any adapters for attaching dishwashers or filters. Best regards, Tanya

Why does it take a few seconds for the water to stop? The faucet is new.

Asked by: GiGi
Hi, GiGi! Thank you for your question. With our high arc faucets, the water does take a few seconds to drain out the excess water after shutting the water off. If the faucet leaks continuously after shutting off your water, please contact our customer service line so that we may help you further. Best Regards, Rosanna

can i hook up a portable dish washer?

a separate aerator attachment is required for our portable dishwasher. The dishwasher hose connector pulls down and then snaps onto the aerator attachment that is connected to the faucet. Does Delta have a solution for a Delta faucet number 21996LF-SS?
