Overview
The Delta Faucet Leland 9178-AR-DST is a single-handle pull-down kitchen faucet finished in Arctic Stainless (AR), a cool-toned brushed metal look that sits confidently between classic chrome and the warmer hues of brushed nickel. It's part of Delta's long-running Leland collection — one of the brand's most recognizable lines — and the 9178 model represents the pull-down variant aimed at homeowners who want genuine functionality without stepping all the way up to a professional-style faucet.
Delta positions this faucet squarely at the remodeling and new-construction market: households that cook regularly, care about how their kitchen looks, and want a faucet that will still work flawlessly five or ten years down the line. It's not a budget pick — street prices typically range from roughly $200 to $300 — but it's also not a luxury splurge. It occupies a sweet spot where build quality, warranty coverage, and design refinement all converge.
Under the hood, the 9178-AR-DST ships with Delta's Touch-Clean spray holes, a MagnaTite docking magnet to keep the spray head locked in place, and the brand's proprietary Diamond Seal Technology cartridge. If those sound like marketing terms, this review will explain exactly what they mean in practice and whether they actually make a difference during daily use.
Key Features
A powerful integrated magnet snaps the pull-down spray head back into the spout body with a satisfying click, eliminating the drooping wand problem common on cheaper pull-down faucets.
Delta's ceramic disc cartridge is coated with a diamond-like carbon finish, drastically reducing friction and wear. Delta claims it lasts up to five million uses — equivalent to decades of daily cooking.
A single button toggles between a smooth aerated stream and a powerful spray with enough force to rinse produce and dislodge stuck-on food from pots. There is no dedicated pause button on the spray head itself; to stop flow mid-task, you must return the handle to the off position, which closes the valve entirely.
Soft rubber nozzles on the spray face let you wipe away calcium and lime deposits with a fingertip rather than soaking the head in vinegar. A small but genuinely useful detail.
The AR finish is a PVD-coated brushed stainless that resists fingerprints and water spots better than polished chrome, while complementing both warm and cool kitchen color schemes.
The faucet connects directly to the water supply with fewer joints than traditional assemblies, reducing potential leak points and using up to 20% less material than industry-standard valves.

Performance
In day-to-day use, the Leland 9178-AR-DST performs exactly how a well-engineered faucet should: quietly and reliably. The single lever moves smoothly through the full temperature range thanks to the Diamond Seal cartridge — there's no stiff or gritty spot in the arc, which remains true even after months of regular use. Hot-to-cold response is immediate, with no sluggish lag that you sometimes feel on lower-tier valves.
The MagnaTite docking system is one of those features that sounds like a gimmick until you've lived with a faucet that lacks it. On pull-down faucets with a simple friction-clip return, the wand gradually begins to sag over time as the clip loses tension. The magnet in the Leland keeps the head locked flush to the spout body year after year. The snap-back action is positive and satisfying rather than flimsy — you can feel the magnetic pull begin to engage about an inch before the head seats fully.
Water delivery is strong and well-formed. The aerated stream produces a clean, non-splashy column ideal for filling glasses or pots, while the spray mode fans out into a useful coverage pattern for rinsing large cutting boards, colanders, or the sink basin itself. Flow at 1.8 GPM feels adequate for almost every kitchen task; it won't fill a large stockpot as fast as a commercial-style faucet at 2.2 GPM, but the difference in everyday use is minor. The included braided supply lines connect easily, and installation for a competent DIYer typically takes under an hour with standard under-sink access.
Installation tip: Delta includes a weight on the pull-down hose to help retraction. For best magnetic docking performance, make sure this weight is positioned roughly 8–10 inches below the spray head connection point before securing the hose.
Value for Money
At its typical retail price of $200–$300, the Delta Leland 9178-AR-DST sits above entry-level faucets from brands like Moen but below the high-end bracket occupied by Delta's own luxury sub-brand Brizo or premium Kohler lines like the Sensate. What justifies the price is primarily the longevity argument: the Diamond Seal cartridge genuinely extends service life well beyond what you'd expect from a budget valve, and Delta's lifetime residential warranty means any defects — including cartridge failure — are covered without hassle. For a fixture you'll use multiple times per day, spreading that cost over ten or fifteen years makes the math very favorable.
Buyers who should absolutely consider this faucet: homeowners undertaking a kitchen remodel who want a faucet that won't need replacing within the renovation window, renters who own and are updating before listing, and anyone replacing a pull-down faucet that suffered from the chronic wand-drooping problem. If you're outfitting a rental property or a secondary sink and pure upfront cost is the priority, a Moen Arbor or similar entry-level option will serve you adequately for less money. But for a primary kitchen faucet in a home you plan to live in, the Leland earns its price.
Worth knowing: The 9178-AR-DST is one of several finish variants in the Leland line. The same model is available in Matte Black, Champagne Bronze, Chrome, and Stainless, so you can match existing hardware without compromising on features.
Final Verdict
The Delta Faucet Leland 9178-AR-DST earns a solid 8.6 out of 10. It isn't the flashiest faucet on the market, and it doesn't offer the high-arc drama of a commercial-style spout or the cutting-edge convenience of touch or voice activation. What it does deliver is a thoughtfully engineered, genuinely durable pull-down faucet with strong ergonomics, a finish that holds up over time, and a manufacturer warranty that gives real peace of mind. The headline features deliver on their promises, solving real problems that plague lesser faucets and elevating the everyday experience of using your kitchen sink. For most homeowners looking to invest once and not think about their kitchen faucet again, this is a very smart choice.
Does the Delta Leland 9178-AR-DST come with supply lines?
Yes. Delta includes braided stainless steel supply lines in the box, so you won't need to purchase them separately. This is worth noting since many competing faucets at this price point do not include supply lines.
Will this faucet fit a three-hole sink?
Yes. The faucet requires only a single mounting hole, but Delta includes a matching deck plate in the same Arctic Stainless finish to cover the two extra holes on a standard three-hole sink. The deck plate installation is straightforward and the visual result is clean.
How does MagnaTite docking prevent wand drooping?
Traditional pull-down faucets use a plastic or rubber friction clip to hold the spray head in position. This clip loses tension over time, causing the wand to sag out of the spout. MagnaTite uses a permanent magnet embedded in the spout body and a corresponding metal element in the spray head to create a secure magnetic connection that doesn't degrade with use.
Is the Delta Leland 9178-AR-DST lead-free and safe for drinking water?
Yes. The faucet is certified to NSF 372, which verifies that wetted surface materials contain less than 0.25% weighted average lead content, complying with the U.S. Safe Drinking Water Act's lead-free standards. It also carries NSF 61 certification for drinking water system components.
What does Delta's lifetime limited warranty actually cover?
Delta's residential lifetime limited warranty covers defects in materials and workmanship for the life of the original purchaser, including the finish and all internal components. If the cartridge fails, Delta will send a replacement at no charge. The warranty does not cover damage caused by misuse, accidents, or improper installation, and it applies only to residential (non-commercial) use.
