Rated 5 out of 5 by from perfect faucet really like the features and looks great.

Rated 5 out of 5 by from Works great. Bought 3 weeks ago.from my local plumbing business.
Date published: 2020-05-28
Rated 3 out of 5 by from Average At Best We have had trouble with the faucet coming loose from the counter, the cartridge in the handle sticks making it difficult to use & the shut off area is so tight that it takes a bit to make sure its not dripping. I gave it 3 stars for excellent customer service follow up trying to help fix the issues. Faucet itself is more like 2 stars.

Rated 5 out of 5 by from Wonderful finish and easy to install. Installed this unit about two weeks ago and I consider myself a novice plumber ( Like, I know how to turn the water on and off ). The one issue I had to figure out was after flushing the lines I had very low water flow on the "Hot" side. I ended up watching a youtube video and learned how to take the unit handle apart. I found what I'll describe as small black rubber chunks lodged in the hot water side. I used a toothpick to pry them out ( about 5-6 of them) and put the handle back together. The water pressure is perfect. I chose this faucet because it has a 9" reach and the head is angled at about a 35 degree angle instead of shooting straight down. This specifically was what we wanted for our farm style sink.

Rated 3 out of 5 by from Be sure to measure Bought this product for kitchen but it doesn't extend far enough over the sink so there is water splashed against the back splash, counter top and window sill every time it's turned on. Be sure to take that measurement!!

Rated 5 out of 5 by from Simple, but yet elegant I bought this right before the covid 19 pandemic and wait til last week to have it installed. I am beyond happy. It’s not only beautiful and elegant, it’s extremely functional.

Rated 5 out of 5 by from Love it!! I had it installed this week and love it. First of all it looks beautiful. I really like the spray choices on the hose. The shield spray setting rinses dishes well without splashing water everywhere.

Rated 1 out of 5 by from leaks I have a new house and the fauset work fine for a year,now water keeps running after I shut it off,then when I use the spray and go bact to normal flow, it flows and drips at same time. this fauset is only about 3 years old. I also replace the fauset head washer a couple of times and still leaks . this is my 10th home and I never had problem with a fauset this old

Rated 5 out of 5 by from Like the design Bought this faucet because the other one gave out. Like the heighth of the faucet and the pull down nozzle!
Date published: 2020-05-03
Rated 2 out of 5 by from Hot/Cold control When using the faucet at low flow it is next to impossible to adjust the handle to a position that provides warm water. The setting between scalding hot and cold is negligible. I’ve marked the valve body with an adjacent mark on the handle in what should be a neutral position. In this position at one point the water is cold, and in a second use the water is scalding.
Date published: 2020-04-16
Rated 2 out of 5 by from good but drips Looks good, but drips no matter how it is adjusted. Not Delta quality.
Date published: 2020-04-13
Rated 1 out of 5 by from Stuck in both streams Spray always stuck in both stream and spray. Cleaned it with white vinegar and water as recommended. Still stuck in both stream no matter what button is selected. The cost to replace this AND my faulty cartridge is ridiculous!

Rated 5 out of 5 by from Love my faucet We remodeled our kitchen several years ago, and we’re having issues with the faucet turning off completely. I called delta and they sent replacement parts for free. It was easy to fix and my faucet is like new again!

Date published: 2020-04-07
Rated 3 out of 5 by from Beautiful, but hard to turn off My wife loves the look of her new oil rubbed bronze finished faucet. I really like the all brass construction, especially at this price point. What neither of us like is how you must be very precise in placing the handle in the exact position to turn off the water completely. We’re constantly finding the water dripping and have to again hunt for the sweet spot off position.

Rated 5 out of 5 by from Love it! We installed our faucet about 3 weeks ago. We love the faucet so far. I have a few quirks about it but nothing major. First, when i was installing it, there is small plastic tabs that go under it. Well trying to line up the faucet, i broke one of the tabs. They don't seem important but it did break. So if your installing yours be careful. the other thing is when you have the handle set to hot, it comes out slower than if its in the center position. If you try to get more pressure, you end up taking it out of the most hot position. Not a deal breaker for me. I haven't really used the shield spray that is on it. I don't really think it will work like they say but i cannot really comment on it. I do like the 2 different spray choices that i have though. Overall i think that this is a great faucet for the price. I hope that it will last a long time.

Rated 5 out of 5 by from Excellent features! Replaced my lower faucet with a high arc pull down faucet and it’s fabulous!
Date published: 2020-04-01
Rated 5 out of 5 by from The ability to move it to either side of our sink. We needed to replace our old faucet & we are so happy with this one.
Date published: 2020-04-01
Rated 5 out of 5 by from Great Value, Good Quality For a DIYer like myself, I found the faucet to be of good quality, well built. Installation was fairly simple and the instructions were easy to follow.
Date published: 2020-03-30
Rated 5 out of 5 by from Quality Product! The installation was pretty easy. I had to go back and reread the directions a few times, as I was not sure that the faucet should sit directly on the granite countertop, or if I should use the trim piece. It seems to work fine either way.
Date published: 2020-03-29
Rated 5 out of 5 by from Great Convenience I love my new faucet. Using all the different streams of water has made cleaning a breeze. The pull down feature sprayer is quite a convenience I use all the time. The sleekness of the faucet looks great with my sink.
Date published: 2020-03-29
Rated 4 out of 5 by from Good product Bought about a month ago and was looking forward to the shield feature. The water had to be on with aperture goof pressure to work, but it still sprays all over when cleaning plates etc. Love the faucet but not happy with this feature
Date published: 2020-03-27
Rated 5 out of 5 by from Easy to install Purchased in February 2020. This is the 2nd one of this model I have purchased ( 2 different houses). Like the 3 optional spray choices, pull out faucet to spray sink, And finish choices.
Date published: 2020-03-26
Rated 2 out of 5 by from Temperature Adjustment: VERY DIFFICULT I bought this as part of my kitchen remodel about a month ago. I debated between a Moen faucet and this Leland by Delta. All those reviews that complained about how difficult it is to adjust the water temperature were spot on!!! There is a wide range for scalding your hands and a wide range for freezing off your fingers, but there is barely a range for nice, warm water for washing dishes or hands. All of the other features work fine and I do like the look of the faucet. But I would not purchase this again.
Date published: 2020-03-24
Rated 5 out of 5 by from Easy install DIY, classic design, great price I originally had a Grohe faucet that after 5 years leaked. I paid over twice as much for that one compared to this Delta faucet which looks and works better than the Grohe faucet.

Q&A

This picture shows that it toggles to spray, so just making sure it does?

Asked by: Lorrie
Thank you for your question. Delta Faucet model # 9978-DST does switch from spray to stream.

I would like to take off the faucet head because it has begun to spray - I assume build up is inside the head. I see the little piece you can push in but it doesn't want to come apart from the hose easily. Is there a trick to take the head off?

Asked by: Christy
Hello Chritsy, Thank you for your inquiry! The wand/sprayer assembly of the Delta Leland Pull-Down Kitchen 978-AR-DST faucet, an be remove by simply unscrewing it from the end of the hose assembly. This should be done by hand only. Best regards, Tanya

The spec indicates a min clearance of 2.5 inches from center of hole for faucet to backsplash. I only have 2 inches.  Why is 2.5 inches needed since the handle goes forward and not back? Will 2 inches work? 

Asked by: Bridget
Thank you for your question, Bridget! The minimum clearance to the back splash is typically suggested for lavatory models with lift rods or for models where the handle does reach backwards. This is still suggested for maximum comfort and ease of use with the handle; however this model can still work with only 2". Best regards, Edward

I see where you have answered the question about the difference between Model 9178 and 9678. What is the difference between those and Model 19978?

Asked by: Kathy61
Hello Kathy 61, Thank you for your question. The Delta Leland Pull-Down 19978-SS-DST faucet is a Home Depot exclusive model and it is similar to the Leland 9178-AR-DST faucet. However, the 9178-AR-DST is designed with the ShieldSpray feature and the 19978-SS-DST model is not. https://media.deltafaucet.com/SpecSheet/DSP-K-19978-SD-DST%20Rev%20C.pdf Best regards, Tanya

What is the tubing for the pull-out spray made of? I am concerned about the materials as the drinking water is now being consumed from this spray.

Does arctic stainless water spot?

Asked by: Melody
Hi, Melody! Thank you for your question. The 9178-AR-DST Arctic Stainless will show water spots. We recommend to wipe clean with a soft towel. If you should need something stronger, we recommend 50% white vinegar and 50% water solution to clean. Best Regards, Rosanna
