Replacement
Replaced same model that was 16 years old. Noticed some changes. Water comes out noisier. Replaced braided stainless steel hose with a rubber one. I hope it holds up as well as the previous one. The brushed nickel finish looks almost like stainless steel.

Easy to use and high quality. Plumber installing had to go get an extra part ($). The only thing we don't love is that the extended nozzle needs a real push to get back in the faucet.

Not Satisfied and it's a Waste of Money.
The faucet had a modern design. Unfortunately, when I installed the faucet I was surprised the way the Standard Flow of water was very "LOW". I do not know what's wrong with my new faucet.

Ok for a while, but doesn't last
Started out ok, but over time it didn't age well. The cartridge needs replaced repeatedly and only lasts maybe a year before it starts leaking again. The finish (as you can see in the photos) didn't last at all on the venetian bronze finish. The connection to the pull down sprayer is rusting.

Doesn’t last long
Needed a new cartridge after a year. Delta said they would only supply 1 for the life of the faucet. A year later the new one is failing and the screw to remove the handle to replace the $50 cartridge has seized so the faucet need to be replaced. Garbage.

Q&A
Is there a visible difference between Artic Stainless and Spotshield Stainless finishes? Is there a difference in care or durability?
Hello,
Thank you for your question!
SpotShield stainless will show spots a less than arctic stainless. There will be a difference if there are two products next to each other in the different finishes.
Please reach out with further questions!

what is the purpose of the red plastic slide switch at the top of the valve assembly?
Hi, Jerry!
Thank you for your question. The switch on the valve assembly is a handle limit stop. Position 1, to the left, allows full handle motion (the full range between “all cold” to “all hot”). The faucet is set in position 1 in the factory. Position 2, to the right, allows half of the normal handle motion (“all cold” to “mixed hot/cold”).
The handle limit stop can be adjusted by the homeowner once the faucet is installed. Setting the handle limit stop in position 2 may help to prevent scalding because it limits the amount of hot water in the mix; however, this handle limit stop will not always prevent scalding because it does not compensate for incoming pressure or sudden water temperature changes.
To change positions of the handle limit stop: remove the handle; move the valve stem to the all cold position so the water is on; change the position of the handle limit stop; turn off the water; reinstall the handle.
Best Regards,
Rosanna

Regarding handle placement and the meaning of 'front' If I'm standing at the sink, is front closer to me and under the spout? Installing on an island where clearance is not a factor, can the handle be in the back, opposite the sink side?
Thank you for your question, LHLIN! The handle placement in "front" would refer to being under the spout and closest to the user. For an installation where clearance does not matter, you can install this model with the handle facing to the back since the spout swivels 360 degrees.
Best regards, Edward

installation on a mica countertop w/farm sink
How far back from a farm sink would be a safe installation for this faucet on brand new mica counter tops?
new kitchen,
Thank you for your question. The spout extends 9 1/4" from the center of the faucet to the center of the aerator and we advise to allow 2 1/2" clearance to the backsplash. However, it is up to you to decide where to install the faucet in your installation. Please refer to the Technical Specifications for more measurements.

Does the leland arctic stainless 978-ARWE-DST come with a soap dispenser?

Does this have to be mounted 4" apart or is 5 or 6" possible?
Dear Mary,
Thank you for your question. The Delta Leland Kitchen faucet 978-WE-DST model has the 4" installation requirement for the outstanding reach of the 59" hose assembly. Installing the the handle and faucet 5" or 6" apart would effect the reach of the hose assembly.

We will have Frigidaire's Gallery series stainless steel appliances in our kitchen. Will Delta's Arctic Stainless or Spotshield Stainless finish match better?
Hi Agolin,
Thank you for your question. There is a slight difference between the Delta Faucet SpotShield Stainless Steel finish and the Arctic Stainless finish. The SpotShield Stainless Steel has a spot-resistant neutral, low-gloss finish. The Arctic Stainless has a blue tint to it and more closely matches stainless steel appliances out in the market today. It is only used in the kitchen.
Best regards,
Tanya

Our faucet is almost 10 years old, and it is hard to keep the faucet from dripping. We have to try a few times and get the on/off mechanism in just the right place for the dripping to stop. What kind of repair might this faucet need? Thanks in advance.

Venetian Bronze Color
Does the Venetian Bronze faucet coordinate with oil rubbed bronze cabinet hardware?
Hello Sophie,
Thanks for your question!
It's always a good idea to take the cabinet hardware and other accessories to a Delta Faucet showroom to see if your chosen hardware will match the faucet and vice versa. The color of the hardware will ultimately depend on the manufacturer, so we couldn't say if it would definitely match. However, Venetian Bronze would probably match an oil rubbed bronze finish, but whether or not it looks good together is ultimately up to you.
I hope this helps!

what is difference between 9978 model and 978 model?
I need the Leland single hand pull down faucet (2 holes) in the brilliant stainless. I've seen both the 978 model as well as 9978...are these different?
Hello WWA,
Thank you for your question!
The 9978-DST is a bar/prep faucet generally used in smaller side sinks. As a result, the faucet itself is much smaller than the 978-DST, which is the regular kitchen sink faucet. You can take a look at each faucet's Technical Specifications for further details.
I hope this helps!

Does this faucet have any lead in it?
Hi, Thank you for contacting us.
We apologize for any inconvenience. We are more than happy to help you.
Delta Faucet Company products that carry the Prop 65 label pictured above include components made with brass, which contains small but detectable amounts of lead—an element included on the Prop 65 chemical list. Brass has a decades-long history of successful use in plumbing applications.
Even though a product may be found to contain a Proposition 65-listed chemical, it does not mean that use of the product will cause cancer, birth defects or other reproductive harm. Nor does it mean that a product is unsafe. All Delta Faucet Company products meet or exceed the requirements of applicable product performance and safety industry standards, as well as the federal Safe Drinking Water Act. We are confident there is no health hazard associated with the installation, use or removal of any of our products.
With DST models, the water does not come in contact with the outer shell of the faucet.

I bought this through amazon and the aerator is 1.8 gpm, we don't have any local code restrictions and I would like to find a 2.2 gpm aerator that would fit this . Someone (from delta) recommended Delta RP53998 2.2 Gpm Aerator, Chrome. This was to big
Thank you for your question, Sharon! I apologize for the confusion with this part and we are happy to help. The aerator RP53998 is not meant for the new Spotshield wand that now comes with this model. We do offer a 2.2 gpm aerator with the correct thread size for your wand as part number RP46827.

We are buying Beverage Faucet 1914-SS-DST and a Leland 9178-nn-DST for the same sink. It comes in -SP- Spotless and -AR-Arctic. Which looks most like the -SS- beverage faucet? We have brushed nickel everywhere else.
Thank you for your question, DavidB! SpotShield Stainless will match the Stainless Steel finish. Artcic Stainless features a cooler color temperature than the warmer Stainless Steel.

I read most of the answers to the questions. If the handle assembly is metal, what material is inside ? Is this product considered a middle quality
or is this still low - end quality?
How much price range do I set to look for a middle quality for single handle pull down/pull out kitchen faucet?
How often do I change the washer?
I didn't buy this yet.
I am checking your homepage to see which one I would like to buy.
Hello Haru Chan,
Thank you for your questions. The internal cartridge for this faucet is manufactured with plastic, but it is a high quality of plastic. The rest of the material this Delta faucet is made with is also of high quality material.

Hi Desperately seeking faucet, Thank you for your question. Unfortunately since the model 9678-AR-DST is a new product launch the product is not scheduled to ship before 12/15/2014. There is no way to get the product earlier.

everywhere online sells this for $179.But on your site & at my local K&B stores it is priced at $385.20? That's a HUGE difference in price! Are there two versions of this product out there? Does the cheaper price mean lesser quality?
Hi Lefty,
We appreciate your interest in Delta faucets. All Delta faucets feature the same quality parts, materials, and workmanship, no matter what kind of dealer sells them. The website shows the product at list price. Dealers purchase the product in bulk for selling it readily to consumers, so they are able to offer a much lower price. However, the quality of all Delta faucets are the same.

Is it possible to increase GPM?
model: Leland 978-RB-DST
I saw a response about increasing the GPM from 1.8 to 2.2 but the model # in the response could not be found when I searched for it.
The response was RP514780RB, but is it really RP51480RB?
Is replacing that part all that is needed? Is there a need to replace the O ring as well? I want to order a new faucet and will have it professionally installed, so want to be sure i order all the necessary parts.
Thank you!
Thank you for your question. The model number for the 2.2 gpm wand is RP51480RB. You will not need any extra orings to replace this wand. The wands will just need to be switched.

Why is your list price $404.50 for Delta faucet Leland Model # 9178-ar-dst and And Amazon list price is $208.00 for the same model
Hi, Rich!
We appreciate your interest in Delta faucets. All Delta faucets feature the same quality parts, materials, and workmanship, no matter what kind of dealer sells them. Delta retail dealers usually sell faucets that include the handles in the boxes. Plumbing professionals and Delta Studio Showrooms sell faucets where the faucets and handles are packaged and sold separately ("LHP" models), giving the customer some additional styling choices. However, the quality of all Delta faucets is the same.

Rosanna

Really 2.5" min clearance to backsplash (4" high)? Want to replace a Moen Aberdeen with your Leland 978-DST. The Moen fits fine with 2" clearance from faucet midpoint to backsplash. Why can't I use 978-DST with same 2" center to backsplash clearance?
Hi, KevinK!
Thank you for your question. We recommend the 2.5" clearance to backsplash for the 978-DST so that everything fits on the top of the sink as well as underneath the sink.

Does the Model # 9178-AR-DST come with a cover/escutcheon?
I see where a previous questioner was told that the stainless steel (SS) model comes with an escutcheon. But, does the Arctic Steel as well?
I read a review of the Model # 9178-AR-DST on an authorized retailer's site that complained that their AR did NOT come with the escutcheon, which I believe is a cover that sits at the base of the faucet, to cover any additional holes used by a previously-installed faucet. The photograph of the faucet does NOT show such a cover. Thank you!
Yes, it does! I asked that question before I purchased mine and verified it at the store at the time of purchase.
