Rated 4 out of 5 by from Love The Look I replaced my old Delta Leland Kitchen Faucet with this new one. I like the look of the new one. It looks special. It took me a little time to figure out how it worked because the stream of water is different. I wish it would not get water spots on it so easily if you do not wipe of the drops right away it leaves spots on it.

Rated 1 out of 5 by from damaged cartridge Had sink and faucet installed by plumber. Faucet had to hit a certain spot when turned off or would leak. Called Delta and they said it is a defective cartridge and they would send me a new one. I do not feel I should bear the expense of installing the cartridge as they sold a defective product and this was bad since it was installed.

Rated 5 out of 5 by from Good purchase I purchased my home in 2016 and it has been more than (6) years and no issues with the original Delta Faucet (9178-AR-DST)! Only recently, the faucet started leaking but since the faucet (9178-AR-DST) has lifetime parts replacement I know I can get the replacement parts at no ($0) additional cost #EASYfix

Rated 5 out of 5 by from Easy install, looks and works great I bought this several months ago and was waiting for new countertops and sink to be installed. Worth waiting for! I’m impressed with the smooth finish and operation of all the spray features.

Rated 1 out of 5 by from Worst faucet I ever bought Bought the 9178 DST it has very little water flow from it . All water lines were flushed. I would never recommend this faucet to anyone.
Date published: 2022-06-15
Rated 1 out of 5 by from Leaks after 2 years, continual replacement This was installed by our builder 6 years ago. I’ve had to replace the valve cartridge 6 times in 6 years, because it leaks. Delta gives us free replacement cartridges, which is helpful, but now the Allen nut that attaches the handle to the valve is jammed, so I can’t replace it anymore. It’s a plastic valve cartridge that wears out very quickly, and clearly a known issue for Delta, since they’ve sent me 5 replacement cartridges over the years.

Rated 5 out of 5 by from Strong stream This Delta faucet has a very strong stream button which I love and it is somewhat easy to install. I live in CA so the water pressure is meh without twirling.

Rated 5 out of 5 by from Smooth Handle Great Hidden Sprayer This Kitchen faucet looks sleek and has a smooth feel. Easy to adjust water temp with just slight effort. Sprayer is buikt into head and works like a champ.

Rated 5 out of 5 by from Great warranty and customer service! My previous Leland (2008) became hard to fix and after many parts replaced was still not working good and recently got a full replacement. Very happy with your Customer Service and warranty,

Rated 4 out of 5 by from Easy install, great magnetic docking. Have owned the Leland kitchen faucet for 3 years. It matches all the Leland faucets in my bathrooms. Could only cut off water from cold side. When cut off from middle or hot it would leak. Lived with it for 3 years and finally solved last week by replacing cartridge. Delta recommended flushing supply lines but my plumber felt cartridge would solve problem and it did. Sorry I waited so long to get it repaired. Delta has always provided great customer service and free replacement parts for all faucets and shower valves over the 16 years I have owned my home. I highly recommend Delta products.

Rated 2 out of 5 by from Nice looking faucet, but problems I have owned this faucet for about a year, and while it looks nice and seems to operate just fine, it is extremely difficult to get it in the off position where it will not drip. It has a tiny little spot where it doesn’t drip. We have weekend guests at our house and they commented how difficult it is to turn off the kitchen faucet without it dripping. I have thought for a long time about replacing it and their comment spurred me on to just ditch the thing. Life is too short to live with that faucet.

Rated 5 out of 5 by from Great water pressure. I love the look and ease of use. Has great water pressure and the pull down spray is awesome. I have not totally got the hang of the water shield yet. Would recommend this to anyone replacing there facet.

Rated 1 out of 5 by from Cheap plastic piece breaks. There is a piece of black plastic in the lever assembly with four tabs that hold the cylindrical trim on the lever snug to the counter, These tabs break easily. The plastic piece cannot be replaced without buying the entire expensive metal trim. Bad design. It costs upwards of $60 to replace the assembly just to fix a 10 cent piece of plastic. Delta does give the option of buying the cheap plastic insert.

Rated 2 out of 5 by from Does not last Got with our new construction house. After 1 year it was hard to use the handle. Started to bind and also had to find the sweet spot to get water to stop dripping.

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
