Our Top Pick: Delta Leland 9178-AR-DST Pull-Down Kitchen Faucet
A refined high-arc pull-down faucet that combines DIAMOND Seal ceramic valve technology, magnetic dock-it retention, and Touch-Clean spray holes into a package that earns its "set-it-and-forget-it" reputation. Rated 9.2 / 10 for value, durability, and ease of installation.
Design & Aesthetics
The Leland's silhouette is unmistakably transitional — it straddles the line between traditional and contemporary with a high-arc gooseneck spout that rises roughly 14.69 inches above the deck. The body tapers cleanly toward the base, and the single lever handle sits at a comfortable 45-degree angle that feels natural to reach across a loaded sink. Whether your kitchen leans farmhouse-rustic or sleek-modern, the Leland's proportions tend to disappear into the design rather than fight it.
Delta offers the Leland in a broad finish palette, which is a genuine differentiator at this price tier. The Spotshield Stainless (AR) variant — the subject of this guide — uses a proprietary coating engineered to repel water spots and fingerprints more aggressively than standard brushed stainless. If you have stainless appliances and a busy kitchen, that alone can eliminate a lot of daily wiping. The Champagne Bronze option has grown enormously popular for warm-toned kitchens, while Chrome remains the entry-price choice and works well in high-contrast or industrial schemes.
The pull-down spray head is compact but substantive — it doesn't look like a tacked-on afterthought. The hose extends approximately 59 inches (150 cm) from the spout, giving you generous reach into large stock pots or roasting pans set on the counter beside the sink. The magnetic Dock-It system (more on that below) keeps the head locked flush to the spout when not in use, which means no drooping or slow descent over months of use — a chronic complaint with older weight-based retraction systems.
Overall, Delta has been careful not to over-design the Leland. Every curve and angle has a functional rationale, and nothing feels gratuitous. For buyers who want a faucet that simply looks right without demanding attention, this restraint is the whole point.
Core Technology Explained
Delta builds the Leland around three proprietary technologies that meaningfully separate it from faucets at lower price points. Understanding each one helps explain why this faucet commands a premium and whether those premium features will matter to you personally.
DIAMOND Seal Technology
The heart of any faucet is its valve — the internal mechanism that controls water flow and temperature mixing. Most budget faucets use a brass ball-and-seat assembly or a low-grade ceramic cartridge that begins to wear, drip, or stick within a few years. Delta's DIAMOND Seal Technology places a diamond-coated ceramic disc at the valve interface. Diamonds are among the hardest materials on earth, which means the seating surfaces resist abrasion even in areas with highly mineralized water.
Delta backs this claim with testing to five million on/off cycles — equivalent to roughly 100 years of typical residential use at 130–140 cycles per day — far beyond a normal residential lifetime. More practically, the valve uses 50% fewer parts than traditional cartridge designs, reducing the number of potential failure points. The result is a faucet that is genuinely backed by a Limited Lifetime Warranty on function and finish, not just a marketing promise.
In Delta's model numbering system, AR stands for Arctic Stainless — Delta's internal code for what is now marketed as the Spotshield Stainless finish. Older catalogs and some retailers still use Arctic Stainless; newer packaging says Spotshield Stainless. Both names refer to the same proprietary anti-spot coating over brushed stainless steel. When in doubt, match the model suffix -AR-DST rather than the finish name.
Magnetic Dock-It Retention
Pull-down faucets have traditionally relied on a counterweight attached to the supply hose to retract the spray head back into the spout. This works well when new but the weight can drag or the hose can kink over time, leaving the spray head hanging loose. Delta's Dock-It system replaces the counterweight with a rare-earth magnet built into both the spray head and the spout collar. When you guide the head near its dock, it snaps home with a satisfying click and stays there with authority.
Practically, this means the head is easier to release (one-handed pull with no resistance from a counterweight) and more reliably retained. After years of daily use, the magnetic connection doesn't weaken the way elastic or spring-loaded systems do. This is one of those features that sounds like a minor quality-of-life improvement until you live with a faucet that doesn't have it.
Touch-Clean Spray Holes
The spray face on the Leland head is made of a soft silicone rubber rather than rigid plastic or chrome. Mineral deposits (lime, calcium) can't bond to flexible silicone the way they adhere to hard surfaces — a quick press with your thumb and the deposit pops free. No vinegar soaks, no descaling tablets, no screwdrivers needed. In hard-water regions where standard spray faces calcify to near-uselessness within a year or two, this feature extends the functional life of the spray head dramatically.
The Leland 9178-AR-DST ships with a 1.8 GPM aerator (compliant with California AB 1953 lead-free standards). In low-pressure homes (below 40 PSI), you may notice sluggish flow. Delta sells optional higher-flow aerators if your local codes permit them. Do not remove the aerator entirely — this can damage the DIAMOND Seal valve over time.

Installation: What to Expect
Delta rates the Leland 9178-AR-DST as a DIY-friendly installation, and for most homeowners replacing an existing single-hole faucet, that assessment is fair. The included InnoFlex PEX supply lines connect directly to the faucet body without separate connections at the valve — a genuine simplification that reduces leak points under the cabinet. Rough installation time for a competent DIYer is typically 30–60 minutes; first-timers working in a tight cabinet should budget up to 90 minutes.
The most common installation challenge with the Leland is the under-sink mounting nut. The lock nut is finger-tightened from below and then torqued with the included plastic wrench — but in cramped cabinets with existing plumbing in the way, reaching the nut squarely can require patience. Delta includes a snap-in deck mounting bracket that holds the faucet body still while you work below, which helps considerably.
The Leland fits a 1-3/8 inch to 1-3/4 inch diameter hole. If your sink has a pre-drilled 1-hole layout, you're ready. If it has 3 holes, use the included deck plate — but measure your hole spacing first (standard center-to-center is 4 inches). If your sink has 4 pre-drilled holes, you'll need a separate soap dispenser or side sprayer to fill the extra opening.
The pull-down hose routes through the faucet body and down through the supply hole, then connects to the hot and cold inlets below. Delta color-codes the connections (red = hot, blue = cold) so there's no guesswork. The spray head docks magnetically from the first use — no break-in or adjustment period required. Once the water is turned back on, run both modes for two minutes to flush any debris from the new supply lines before using the faucet normally.
Even though the supply lines use compression fittings (no tape needed at those joints), any threaded adapter connections under the sink benefit from 2–3 wraps of PTFE tape. It adds less than two minutes to the job and prevents the slow drips that are easy to miss during installation but annoying to track down later.
Finish Options & How to Choose
The Leland 9178 platform is available in six finishes as of the current catalog year. Each finish carries its own model suffix and varying price point. Choosing the right finish isn't just about aesthetics — different coatings have genuinely different maintenance requirements and durability profiles.
Spotshield Stainless (AR) — This Guide
Delta's proprietary anti-spot coating over brushed stainless. Noticeably better at repelling fingerprints and hard-water rings than standard brushed stainless. Best for busy kitchens and stainless-appliance packages.
Chrome (DST suffix only)
Bright, high-mirror polish. Easiest to source replacement parts for. Shows water spots and fingerprints readily — wipe frequently or skip if you have hard water.
Champagne Bronze (CZ)
Warm gold-bronze tone that pairs naturally with cream, off-white, and wood cabinetry. Delta's PVD finish is durable but may show micro-scratches over years of heavy use.
Venetian Bronze (RB)
Dark oil-rubbed bronze look. Rich, traditional character. Can show lighter wear marks where the finish is thinnest. Best for period-style or Tuscan kitchens.
Matte Black (BL)
Bold, flat black powder-coat look. Trending strongly in contemporary and industrial designs. Does show dust and dried water mineral deposits — plan on weekly wipe-downs.
Lumicoat Chrome (CL)
Delta's newer anti-spot chrome variant. Combines mirror chrome brightness with improved water-spot resistance — best of both worlds but at the highest price point in the Leland line.
