The Delta Trinsic 9159-DST is a sleek, high-arc pull-down kitchen faucet in Chrome built around three proprietary technologies: MagnaTite Docking snaps the wand back into place magnetically so it never droops; DIAMOND Seal Technology uses a diamond-coated valve to eliminate leak points and outlast the industry standard by 2x; and Touch-Clean rubber spray holes let you wipe away mineral buildup with a finger. It fits single-hole or 3-hole 8 in. center decks (optional deck plate RP64070 sold separately), delivers 1.8 GPM at 60 psi, and carries ADA compliance certification. The high-arc gooseneck swivels 360 degrees with a 20 in. retractable hose, making it well-suited for deeper sinks and everyday prep work.
Does the spray head on the 9159-DST actually stay docked or does it droop over time?
The MagnaTite Docking system uses a strong integrated magnet to hold the wand in place, which is specifically designed to prevent the drooping that is common with gravity-clip systems. Reviewers consistently confirm the docking stays secure with normal use, though a small number of long-term owners (3+ years) have reported the magnet weakening. Delta's Lifetime Limited Warranty covers defects, so contact Delta if docking performance degrades.
Is the deck plate (escutcheon) included for a 3-hole sink installation?
No. The 9159-DST ships with everything needed for a single-hole installation. For 3-hole sinks, you need to purchase the Trinsic escutcheon RP64070 separately. It is available in matching finishes and covers the extra holes without any visible gap.
What is the flow rate, and does this faucet qualify as WaterSense?
The 9159-DST flows at 1.8 GPM at 60 psi. Delta lists it as Water-Efficient and CalgreenCert certified. At 1.8 GPM it meets EPA WaterSense criteria (which requires 1.8 GPM or less for kitchen faucets), making it a solid choice for water-conscious renovations.
How difficult is the installation, and what supply line connections does it use?
Most homeowners with basic plumbing comfort rate installation as straightforward. The faucet ships with integrated InnoFlex PEX supply lines pre-attached, so there is no separate supply line to connect at the faucet end. The lines terminate in standard 3/8 inch compression fittings that connect directly to shut-off valves. No special tools are required beyond a basin wrench.
Does the Chrome finish show water spots and fingerprints easily?
Chrome is a high-gloss finish that does show water spots more readily than brushed or stainless alternatives. The Delta Trinsic Chrome finish meets 2x the industry standard for corrosion resistance, so it holds up well long-term, but routine wiping is needed to keep it spot-free. Buyers who prefer a lower-maintenance option should consider the SpotShield Stainless variant (9159-SP-DST), which is engineered specifically to resist spots and fingerprints.
What are the most common failure points reported by long-term owners?
Amazon reviewers (1,500+ ratings, 4.4 stars) cite two recurring issues: a small plastic click-stop piece on the spray head that can break within the first year on some units, and overall durability concerns in a subset reporting failure within 2-3 years. However, these represent a minority of reviews — the majority highlight solid construction and reliable performance. Delta's Lifetime Limited Warranty covers manufacturing defects, so affected owners should file a warranty claim directly with Delta.
