Rated 5 out of 5 by from Works great!!! Bought a cheap faucet about 2 weeks ago. Yea I know. You get what you pay for. But this faucet was not much more than the cheap faucet I bought.Should have went with this one first. Didn't care for the Crooked neck, but turns out I love it.

Rated 5 out of 5 by from GREAT FEATURES AND SUPER EASY INSTALLATION We are so happy that we chose a Delta Faucet over all other faucets. We had a plumber install it and in his opinion, it is the best faucet on the market! We love the ease of use and the stainless steel appearance.

Rated 4 out of 5 by from Sprayer leaks I was talked into the Delta 21988LF and paid the extra money for it. It was easy to install and looked great. It worked great until after 9 months. Then the sprayer would not stop leaking from the on/off button. I wrote to customer service and hope to get it replaced very soon.

Rated 5 out of 5 by from Just what I wanted This faucet was bought to replace an old leaky model of another brand. I like the high arc of the spout and the lever handles. It is easy to turn on and off. The spout swivels smoothly and the sprayer works great. This is an easy to install unit.

Rated 1 out of 5 by from Wonderful replacement How privileged we feel to finally have a faucet that was so easy & fast to install into our kitchen sink in our home. It was unbelievably easy & such an improvement over the replacement faucet we had been using since 2002. We had gotten so used to the idiosyncrasies of the old one that we didn't realize how nicely a faucet can operate & add beauty to a kitchen. We love it!

Rated 5 out of 5 by from Looks good, installs easy and great warranty. I purchased the Model 21988LF over a month ago and replaced a NON Delta faucet that was on a deep sink in the utility room. It was a washer type and over thirty-three years old. I replaced many washers during those thirty-three years and one valve seat. The cold water supply to the old faucet broke one day and WHEN DID IT? You guessed it, when I wasn't home. Water was everywhere when I returned. I recently read the one and two star reviews about the flimsiness of the 21988LF faucet handles. People stated that they flex when turned off. Folks these are washer-less faucets and are made to be turned off and on with one or two fingers. Yes during the "good ole days" the washer type faucets offered more resistance to movement and at times you really had to crank down on them to stop a drip. When that happened it was time to replace the washer but most people didn't and continued to apply more twisting force to obtain a complete drip stop. As I stated earlier, washer-less faucets are manufactured to be turned on and off with very little resistance so all the extra seals, brass and steel aren't necessary to make a good product. All of the remaining faucets in my house are washer-less. All but three are Delta and that is another story as to why they are another brand. I have replaced washer-less components in the three that aren't Delta five times since they were installed. In over thirty-three years not one of the Delta faucets has ever leaked. If one of the Delta faucets starts leaking I know I will be able to purchase a replacement part instead of a new faucet. Over forty-five years ago a plumber told me to by only Delta and if something malfunctioned I would either be able to find a part to fix the problem or Delta would replace it. So far not one Delta faucet is dripping or spewing.

Rated 5 out of 5 by from Easy to install! I like it because it does NOT have Ceramic cartridges and the cost of replacing bad cartridges is Much more reasonable!

Rated 5 out of 5 by from Beautiful I bought this a couple of years ago, and the sprayer started leaking almost immediately. Delta replaced it, without question, even more than a year later. The service was great and the replacement arrived within days. The new sprayer, so far, works great, with no leaks. This set looks great. I just wanted something different than chrome.

Rated 5 out of 5 by from Works really well. My plumber bought this and installed it last week. I am enjoying it, especially the sprayer.

Rated 3 out of 5 by from Sprayer started leaking after 3 days Sprayer started leaking after using cold water through the spout. Spout also seems rather loose where it threads into the base. Faucet is also very light weight and I'm not sure how long it will last.

Rated 5 out of 5 by from install, appearance, quality of material, simple We purchased this a week ago from our local Home Depot. Exactly as advertised. Our handyman suggested Delta. This replaced a previous Delta faucet, and we like it a lot.

Rated 4 out of 5 by from Nice replacement faucet...but Bought this faucet to replace one that when turned on, sprayed in the air like a geyser! Install on this one was easy for a do it yourself person, women included! 2 years later, sprayer is spraying water and leaking heavy when I turn on the hot or cold water. Other than that, the faucet works fine. Need a replacement sprayer asap!!

Rated 5 out of 5 by from no complaints so far We installed this faucet a couple of weeks ago and have been very pleased. Easy to install, no leaks, plenty of pressure. The sprayer is so much better than the last one I had. We had a Moen for many years but the sprayer was never very good. I would definitely recommend this faucet.

Rated 1 out of 5 by from Terrible water pressure My contractor bought this faucet. It made the water pressure go way down and now after only 3 months it is down to nothing. I had a plumber come out and nothing was wrong with the line it was just the faucet. For a new faucet this is disgraceful!

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
