Rated 2 out of 5 by from Spray Head sucks Don’t like the spray head
Date published: 2025-09-15
Rated 3 out of 5 by from it's fine enough Installed one of these 15 years ago. It's been a fine faucet. The little cap that covers the set screw was lost almost immediately. Today I replaced it with the same faucet and what do you know, the little plastic cap doesn't fit to cover the set screw at all. HOW have you guys not figured out in 15 years of selling this thing that the little plastic cap doesn't fit into the set screw. The shape is completely different. I tried to glue it but I'm definitely losing it into my garbage disposal eventually. The rest of the faucet is good and fine. Just a super annoying lapse in attention to detail.

Rated 4 out of 5 by from Delta Kitchen Faucet The faucet is nice but I can definitely tell the material is lesser quality than the one I purchased 18 years ago. You can tell that the materials aren't as good, much lighter weight. But it works as expected.

Rated 1 out of 5 by from Poor design and engineering Will not output hot water. Internal mechanism is broken and will only supply cold water.

Rated 2 out of 5 by from Started dripping within months Had a plumber purchase and install this faucet. It was ok for a few months and then started dripping. After reading some of these reviews I’m thinking I need to replace the cartridge, but I kept thinking it was too soon. I should still be under warranty but the plumber disposed of the packaging. Is there anywhere else to find this information?

Rated 3 out of 5 by from Looks great ….not happy with the diamond cartridge I've hd this installed when i had a granite top installed about 5 years ago still looks great. Not very pleased with the “diamond cartridge” i had to replace it twice, this time will be #3 . The first time it leaked into,the sink, the second time under the sink and onto the floor which had to be replaced…..in their defense they did send me a replacement cartridge free of charge. Now it is leaking again. Not sure what to do this time.

Rated 1 out of 5 by from A startling decline in quality My previous Leland lasted from 2008 until August of 2021 when the aerator began to deteriorate. Because at some point they changed the design of the Leland, I wound up having to get an entirely new faucet which Delta provided under warranty. I had to get this installed at considerable expense, and exactly 1 year later (08/22) I had to have them send me a new cartridge under warranty because it wouldn't close completely and it leaked. It is now 3/1/24 and it's leaking again, and will need its third cartridge in 3 years. Keep in mind my original made it 12 years on one cartridge. Furthermore, the old Leland used a mechanical clip to retain the sprayer head, but the new one uses a magnet. That magnet failed almost immediately and now the sprayer head just hangs. Overall I am incredibly disappointed in the nosedive in quality that Delta has apparently taken. This is also a $650 faucet, not the $59 Lowe's builder special, which makes this dismal quality all that more unacceptable. Do better, Delta.

Rated 1 out of 5 by from 2nd one and also JUNK!!! The second Leland and it's JUNK just like the first oneIt is very difficult to get this faucet in the exact position where it doesn't drip. There are many reviews saying the same, and I am frankly baffled that there are so many 5 star reviews as well. Delta's response is to engage in a lengthy process to flush out the hot and cold lines. I had this faucet for about 9 months and finally threw it out. The faucet I replaced it with requires no such flushing and easily turns off without drips. In my opinion this faucet design is defective and should not be sold.  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. e to hire my plumber to replace. To date, I will have spent too much time and effort phoning Delta and almost as much on my plumber as I have these faucets. Although I love the look, I can't afford to use Delta products ever again. So disappointed.

Rated 5 out of 5 by from solid faucet no complaints good pressure and temp select, install was easy with included wrench. magnet failed within 6mos, but delta sent replacement magnets and it's been 3yrs no issues. cleaned out both screens once a year (not hard water) had some problems with dripping bit tightened up the bolt behind sprayer and not an issue. can't take apart sprayer head with wrench...way too hard as there's a slight leak from bottom (separate from the stream or sprayer) and I bet a clean out would help, but it's stuck and included wrench with teeth cams out before i can loosen it...very minor beef after 3 yeara. LOVE THAT LASER STREAM!

Rated 5 out of 5 by from LOVE THIS FAUCET 😍 We've only ever purchased faucets from Amazon and box stores like home depot, only to have them fall apart within a year, at the most. This time, at the suggestion of friends who are contractors, we purchased our delta faucet from a local contractors warehouse. It was considerably more than the diy home improvement boxstores for the seemingly same product. But the quality of the overall weight, metal and other components is far superior and worth the price. Apparently manufacturers use a different grade of metals for faucets sold through an actual contractor's store versus the box stores even though on the surface they look the same. I have to say, even though I balked at this initially, and cringed at the price difference for what looked to be the same item, there's absolutely no comparison. I'll never go back to Amazon or the box stores for another faucet again. We had purchased the Delta Leland model #9178ARDST, Clos to 3 years ago and I absolutely love it and have not had a single problem with it falling apart or any other mechanical issues

Rated 2 out of 5 by from Great faucet if you can stop it from leaking! I bought this 978-SD-DST faucet in August of 2022. It has performed fine until about a week ago when it refused to shut off. I followed the maintenance directions in the installation instructions but it failed to correct the problem. I have contacted Delta in the hope that they will send a new cartridge ASAP, as I hate to waste water, especially like this. Maybe they can send two, so when this fails again in a year or two, I will be prepared.

Rated 1 out of 5 by from Not a happy Delta customer I've had this faucet for almost 3 years. I had to replace the DIAMOND Seal handle cartridge in October of 2022. I need to replace it again, Adjusting the water temperature is impossible and very frustrating with this faucet. It's either screaming hot, or not hot enough. I am seriously considering replacing it altogether.
Date published: 2023-11-26
Rated 1 out of 5 by from Looks great, not happy with shut off I purchased Delta - 9178-SP-DST three years ago and while it still looks great, it constantly needs the Cartridge - DIAMOND™ Valve - 1H replaced. Thankfully the company sent me three replacements. But very unhappy to have to keep installing the part every year. Thankfully my neighbor is a contractor. Looks like I have to call and ask for more cartridges again. Maybe I got a lemon?!

Rated 5 out of 5 by from Excellent customer service! We bought this faucet 6.5 years ago and recently developed a slow drip. I looked up our faucet model number on the web site and called customer support. In a few minutes my order was placed for the replacement part. It's amazing that a company still has this level of customer service - it's world class! Thanks Delta, it's been a pleasure doing business with you!

Rated 5 out of 5 by from Great Style & Performance Bought this kitchen faucet to replace a 23 year old Kohler. We chose the Delta Leland because of the style-especially the large handle for my husband who has big hands and the Shield Spray which concentrates the spray on dishes that you rinse. My husband installed this faucet. I would definitely recommend the Leland. It is a wonderful addition to our kitchen.

Rated 4 out of 5 by from Nice Faucet I bought this early this year; had it installed by a plumber. Works well and is convenient, but now and then it will go on or go off when my hand gets very close to the faucet but does not touch it. That can be annoying and wet. I would like it looked at but am not interested in another large bill. Faucet was expensive, as was the installation.
