Rated 4 out of 5 by from 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.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from Great features I love my new faucet. Hands down, it makes daily cooking easy and was easy to install. I really appreciate the customer service I received with this product. Thank you

Rated 3 out of 5 by from 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.

Rated 2 out of 5 by from 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.

Rated 1 out of 5 by from 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.

Rated 1 out of 5 by from This is trash This is absolute trash. I can't believe you sell this crap. It never shuts off and it drips. This should last us forever. We are the original owners of the house. Delta fix it!

Could you use this in a sink with 3 holes and purchase a soap dispenser for the 3rd hole ?

Asked by: Jill
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, Dave

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.
