Delta 9178-AR-DST Review – Leland Kitchen Faucet

The Leland 9178-AR-DST is one of the most popular models in Delta’s line of kitchen faucets. Moreover, it’s also one of the best pull-down faucets available on the market. This kitchen faucet is designed in an elegant style that offers timeless elegance and combines it with modern functionality. It’s got all it takes to accentuate the aesthetic appeal of any kitchen. Read on our Delta 9178-AR-DST review to take a closer look at what this kitchen faucet has to offer.

Our Review


The creation of the design was inspired by a teapot. The faucet features a high arc spout and a beveled teapot spray head. There are also no ornamental rings in design and only soft lines of the body and handle. All this creates a charming elegance that would look excellent in a traditional kitchen setting, though it can also fit some modern kitchen decors.

Delta makes this Leland faucet in a variety of finishes, so you can pick one that would match the rest of your kitchen fixtures. You can get it in the SpotShield stainless finish, which has antimicrobial protection, as well as resistance to water spots and fingerprints. There’s also the option of the Venetian bronze finish that gives the faucet a more rustic feel. For those who prefer a shinier finish, there’s also chrome finish. And for those who like a more neutral shade, there’s the arctic stainless finish.


The Delta 9178-AR-DST Leland comes in a high-arc design, with the overall height measuring 14.88 inches, while the reach of the spout is 9.2 inches. This gives you plenty of unobstructed room in the sink, so you can easily fit there large pots or other cookware.

It’s important to take the faucet dimensions into your buying considerations. If you have kitchen cabinets or any other obstructions hanging over the sink, measure the distance between them and the sink to make sure that you’ll be able to accommodate the height of the faucet.

Also, compare the size of the faucet in relation to the size of the sink. If you have a very small sink, for example, the Leland kitchen faucet might just look oversized. Your faucet should look balanced in proportion to the sink.

360 Degree Swivel

You can also swivel the spout 360 degrees, which means that you can access the faucet from any direction. You’ll find this feature especially useful if you’re installing the fixture on a kitchen island. It will allow you to rotate it to any direction that you need to access the faucet from. For example, you won’t have to walk all around the kitchen island just to fill a pot of water. You can just turn the faucet backward and access it from behind.

You’ll also find this swivel feature useful if you have a two basin sink. It allows you directing the water flow to whatever basin you’re working from.

Pull-Down Design

It’s a pull-down kitchen faucet, so you get the extra functionality of an extending spray head. It’s connected on a 20-inch hose, giving you enough reach to clean the entire sink or get up-close for rinsing your cookware. You can also carry out out-of-the-sink tasks. For example, if any of your pots don’t fit inside the sink, you can just fill them up on the countertop beside the sink. The hose is also flexible, so you can easily maneuver the spray head in all the directions.

Delta has designed for their pull-down faucets the MagnaTite docking system. The spray wand is kept in place connected to the spout using a powerful magnet. Just give the spray head a gentle tug and it will smoothly extend. After you finish working, raise the wand and the magnet will pull the head back into place.


The faucet is designed to help you get your kitchen sink tasks done quickly and easily. It gives you the option of using either the spray or the stream mode. So if you need to quickly fill a pot of water, just use the stream mode. However, if you need to do rinsing of the cookware or vegetables, press the button on the spray head and switch to the spray mode.

The spray mode also works with the ShieldSpray technology. It produces a more powerful jet of water, so you can easily rinse off any stubborn mess. The spray is also concentrated, limiting the amount of produced splatter.

Diamond Seal Valve

One of the features that determine the durability of a faucet is the quality of the valve. This Delta 9178-AR-DST Leland fixture comes with a Diamond Seal valve, which is one of the highest quality valve technologies on the market.

The valve of this faucet features a tough diamond coating. This helps to keep away any potential metal contaminants and provides drip-free performance for years to come. Delta’s tests of this technology have shown that such faucets can last up to 5 million uses.

Touch Clean Technology

Delta has put a lot of thought into designing a faucet that is easy to keep clean. One of such innovations is the Touch Clean technology that helps to prevent mineral buildup on the face of the spray head. It features soft, rubber nubbins that can be easily wiped clean with just a touch of a finger.


The installation should be an easy process for those with at least a bit of DIY plumbing experience. Otherwise, if you want to ensure proper installation, it might be a good idea to hire a professional plumber.

Everything you’ll need for the installation, you’ll find in the box, including the integrated Innoflex PEX supply lines. The faucet can be mounted on a 1 or 3 hole sink or countertop. With a 1-hole mount, you can clear up your sink space and make it less cluttered. You can also mount this Leland kitchen faucet on a 3-hole sink. However, for this case, you’ll need to use the optional escutcheon.


Delta guarantees the quality of this faucet by providing a limited lifetime warranty. Moreover, the company also has excellent customer support. So if you’ll have any problems with the faucet, a replacement part could be a phone call away.

Also Available With Touch2O

You can also get the Delta Leland model with the Touch2O technology. It brings more modern convenience by allowing to control the water flow with just a simple touch. If your hands are full or dirty, you can just use your elbow or forehand to touch anywhere on the spout and this will get the water flowing. To turn the water off, just tap it again.

This technology does add to the price of the faucet, so just consider if you would find this feature useful or not.
