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.

Worked well for a while, but didn't last
I've owned this faucet for 13 years and at first it worked well. Magnetic docking of pull-down spray is a nice feature, but the magnet has rusted over time. The valves don't last very long. I've probably installed 4 or 5 valve body's in this. It fails the same way every time, when it starts leaking when in the down/off position. You have to rotate the handle in a circle left or right to get it find the sweet spot where it actually shuts off. The finish on both the handle and the top of the spout is basically gone. It didn't last more than 5 years in daily use. At this point I'm sick of replacing valves and will likely replace the entire faucet, unless Delta will "warranty" it.

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
What is the distance through air from the edge of the sprayer to the friction spacer when the faucet is fully retracted?
Thank you for your question. We had one on display and I measured it. With the hose fully extended, you will have 21 inches of hose exposed.
Date published: 2024-03-28
It says 2 or 3 hole installation. How does it work on a 3 hole? Also any similar setups on black?
Hello!
It will be a three hole installation if the optional soap dispenser is also purchased.
Please reach out with further questions!

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.
Best Regards,
Rosanna

What is the circumference of the base of this faucet? I'm trying to figure out if there is enough clearance from my backsplash.
Hi Mike,
Thank you for your question. The recommended clearance to the backsplash is 2 1/2" from the center of the installation hole. The base of the faucet is 2 39/64" in diameter.

what do the initials mean following model # e.g. 9678 sp-dst or 9678 ar dst
Hi, Maximillion!
Thank you for your question. The 'SP' in the model Delta 9478-SP-DST faucet indicates the finish for the faucet is SpotShield Stainless. 'AR' indicates Arctic Stainless. The 'DST' stands for 'Diamond Seal Technology'.

Rosanna

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.

How far does the handle push back?
We are installing this in a small bar area. The faucet will sit fairly close to the wall. I want to make sure that we'll be able to fully adjust the water temperature without the handle hitting the wall behind it. Thanks.
Hi dinomomma, Thank you for your question. The recommended minimum clearance to the backsplash/wall for model 9678-AR-DST is 2-1/2" from the faucet center/center of mounting hole to the wall. The handle at max hot temperature only extends approximately 1/2" past the base of the faucet.
Thanks,
Dave

Could you use this in a sink with 3 holes and purchase a soap dispenser for the 3rd hole ?
Hi Jill, Thank you for your question. You can purchase a soap dispenser to fill the 3rd hole. Our RP50813RB soap dispenser coordinates with the Leland faucet collection.
Thanks,

Please give me advantages and disadvantages of the "Touch-Clean" spray holes?
Am I guessing that you can flex a rubber disk with holes in it to knock off water deposits? And is this disk less likely to last as long as a metal aperture plate? And is this disk replaceable by homeowner, or do I have to buy a whole new faucet?
Dear RiverCityKen,
Thank you for your inquiry! The wand assembly of the Delta Leland Pull-Down Kitchen 9178-SP-DST faucet has the Touch-Clean feature. This simply means you can rub your fingers over the nubs of the spray nozzle for cleaning. The design of the product makes removing deposits easier.
Best regards,
Tanya

I have the delta 9178-AR-DST kitchen faucet. It was already installed when i moved in. The faucet base moves too freely and thespout moves completely all the way around. Is this normal? I was not left with the wrench that came with this to tighten any nut
Hi, George!
Thank you for your question. The Delta 9178-AR-DST faucet spout does swivel 360 degrees. The base assembly should not move. We do recommend to seal the escutcheon plate (base assembly) with silicon sealant to the sink or counter to secure this.

Rosanna

What is the difference between arctic stainless and spot clean stainless?
Hi, MB2013!
Thank you for your question. Arctic Stainless is a brushed finish like Stainless Steel. Over the years, the color of stainless steel used on appliances and sinks has migrated from warmer tones, with more red in the color spectrum, to lighter tones where blue is more predominant. Arctic Stainless features cooler metallic tones, following a trend seen throughout the kitchen. SpotShield Stainless is a spot-resistant, warm, low-gloss finish with warmer tones, similar to brushed nickel.
Best Regards,
Rosanna

Is there a matching filtered water tap?
I am looking for a recommendation of a separate water tap for filtered water that matches the "Arctic Stainless" finish. What would you recommend?
Thank you for your question. Delta Faucet offers two different styles of beverage faucets in the Artic Stainless finish. Delta Faucet model # 1914-AR-DST is a tradtional faucet and Delta Faucet model # 1977-AR-DST is a transitional faucet.

can you shorten the innoflex per supply lines?
Hi, Chili!
Thank you for your question. We do recommend to bull-horn or wrap the supply lines on the Delta 978-RBWE-DST if they are too long. If the supply lines need to be cut, please view the instructions on page 5 of the maintenance and instruction guide for the faucet here:

What is Arctic Stainless and how is it different from spotless stainless?
Thank you for your question, Susan! Arctic Stainless reflects the trend toward cooler toned kitchen appliances and is evident in the slightly blue hue as opposed to our Stainless Steel finish which has a warmer color.

I want to replace a bar sink faucet with a 4 inch spread. Can I get a spotshield plate to fit a 4 inch spread for this faucet?
Hi, JRW2020!
Thank you for your question. At this time, the only escutcheon plate that will fit the Delta 9678-SP-DST Faucet is the Delta RP47274SP Escutcheon Plate which is 8" centers. We do not make a 4" center escutcheon plate for the faucet. We do apologize for any inconvenience this may cause.

are the valves ceramic, the spray head metal... the button, plastic or metal? and, no "electronics"? shopping online, I find not all of the features are made clear... I like the look and has good reviews... please don't use this as an excuse to spam...
Thank you for your question, Wednesday! We apologize for any confusion and are happy to clarify. This is the standard, non-electronic or "Touch Activated" version of the Leland Kitchen Faucet that uses a ceramic Diamond Seal Technology cartridge. The spray assembly is non-metallic as is the button but this does include ShieldSpray Technology.

can the spray head come apart so you can clean it if the holes get plugged up
Hi, Cheryl!
Thank you for your question. The Delta 9178-DST Faucet sprayer assembly can be removed from the hose assembly and cleaned by soaking the whole sprayer in a solution of 50% white vinegar and 50% water mix for an hour or even overnight.
