How to Identify Your Delta Faucet: Model, Trim, and Cartridge [2026]

How to identify your Delta faucet starts with a decision most homeowners get wrong the first time: ordering a replacement cartridge before confirming which one the faucet actually uses. Delta’s own service-parts workflow assumes you already know the model number — type it into the search box and it routes straight to that product’s parts diagram — but most people standing under a leaking sink don’t have that number memorized. Delta

This guide walks through where Delta actually hides the model number, what the visible trim tells you before you touch anything, how to read the cartridge once it’s out, and what to do when none of that gets you a confirmed match.

How to Identify Your Delta Faucet: Start With the Model Number

The highest-confidence identifier is the product model number itself, because Delta’s support workflow is built around it — enter a known model number into the search box and it takes you straight to that product’s detail page, complete with the parts list and diagram. Delta

If you don’t know the number, Delta’s guided product identifier is the second-best path. It asks a short series of questions — which room the faucet is in, the product type, a description of what you’re looking at — and narrows down to matching products from there. Delta That guided flow is worth trying before you disassemble anything, because it’s built on the same visible cues covered in the next section.

Read the Visible Trim First — Logo, Handle, and Spout

Before crawling under the sink, spend ten seconds on the faucet in plain view. Delta’s own product identifier starts with the visible trim — the brand mark, handle shape, escutcheon shape, and spout profile — before it ever narrows to a specific model. Delta

On kitchen faucets, compare the pull-down or pull-out wand, the high-arc shape, handle placement, finish, and deck plate against Delta’s product pages. Delta’s Essa 9113-DST, for example, lists its collection, model number, finish options, installation type, valve type, and a parts diagram link all on one product page — the kind of detail that lets you visually confirm a match before you buy anything. Delta 9113-DST If your kitchen faucet has integrated braided supply lines built into the body (Delta calls this InnoFlex PEX), that’s a feature tied to the “DST” suffix in the model number and Delta’s DIAMOND Seal Technology line — worth noting before you search. Delta 9113-DST

If what you’re actually looking at is a shower or tub valve behind the wall rather than a sink faucet, the trim-versus-rough-valve split works differently — see our dedicated guide to identifying your Delta shower valve for that version of this problem.

Check the Box, Manual, or Supply-Line Tag

The fastest confirmation is paperwork. Check the original box, installation guide, maintenance sheet, or parts diagram if any of it is still in the house — Delta organizes exactly these documents under “Documents & Specs” on its product pages, including technical specifications, maintenance and installation sheets, and parts diagrams. Delta 9113-DST Other manufacturers confirm the same logic applies industry-wide: Pfister says its model number is printed on the product package and instruction manual, and Kohler says a model identifier may show up in packaging, literature, specification sheets, or stamped directly on the product. Pfister Kohler

No paperwork? Look under the sink before taking anything apart. Most Delta faucets manufactured from roughly 2012 onward carry a small model-identification tag zip-tied to one of the flexible supply lines — usually the cold side — often marked “DO NOT REMOVE” in bold letters. Trace the braided supply hoses up from the shutoff valves with a flashlight; the tag is typically within the first 6 to 12 inches. Kohler explicitly lists product stamping as a model-number source, and Pfister points homeowners to packaging and manuals before relying on visual filters — the same under-sink habit applies to Delta. Kohler Pfister

Pull the Handle and Read the Cartridge Cap Color

If the tag hunt comes up empty, the cartridge itself is often the most reliable clue — and you’ll need to remove it for the actual repair anyway. Shut off the water at the supply valves first. Delta’s own support answer for the RP19804 cartridge describes the sequence: remove the handle, slide off the finished sleeve, then unscrew the bonnet nut to access the cartridge underneath. Delta RP19804

The escutcheon — the decorative plate the handle sits against — can be a clue on its own. In Delta’s own support Q&A, a homeowner identified an old 1400-series valve just from the outside plate, and Delta confirmed that was consistent with the RP19804 pre-2006 family. Delta RP19804 Screw position matters too on older Monitor valves: Delta says current T13/T14 trims can update an older pre-2006 1400-series valve only when the existing trim screws sit at roughly the 1 o’clock and 7 o’clock positions. Delta RP19804

Once the handle is off, the cap color on the cartridge itself is the clearest signal: Delta says the RP19804 cartridge used in older Monitor 1300/1400-series valves has a white top, while the RP46074 cartridge used in newer 13/14-series MultiChoice valves has a gray top. Delta RP19804 Delta’s product listing pins RP19804 to Monitor 1300/1400 tub and shower units made before March 2006, and its current T14232 trim page lists RP46074 as the cartridge for the MultiChoice Universal 13/14 Series — so a gray-top cartridge points to the newer valve family, not the older one. Delta RP19804 Delta T14232

Don’t confuse the visible trim’s model number with the internal cartridge’s repair part number — they’re two different numbers on the same faucet. Delta’s T14232 page identifies the trim itself as model T14232, while the parts list on that same page identifies the cartridge you’d actually order as RP46074. Delta T14232 Similarly, RP4993 identifies seats and springs, not a complete cartridge or faucet — Delta’s parts finder lists it as the fix for a dripping spout (when the water is off) in non-DST faucets, and RP4993 is also included inside the RP19804 kit for Monitor showers. Delta RP4993 Delta Parts Finder Delta RP19804

If you’re working on an older single-handle Delta with an internal ball rather than a cartridge — an older kitchen or lavatory faucet — the disassembly looks a little different: inspect the handle cap area, cam, ball, seats, and springs, since ball faucets rely on a slotted ball, O-rings, and spring-loaded rubber seals rather than a sealed cartridge. The Spruce Once you’ve confirmed the model or the cartridge number, our free Repair Finder can suggest the matching replacement part so you’re not guessing at the hardware store.

Use Delta’s Online Product Identifier (and How Other Brands Compare)

Delta’s “Find Parts and Identify Your Product” page is the manufacturer’s own tool: it accepts a known model number in search, and it offers the guided room/product-type/description identifier described above. Its strength is routing you to a real product page with a parts diagram and part list; its limitation is that it doesn’t publicly decode every date or production code. Delta

That last point matters, because it’s tempting to look for a “Delta serial-number decoder” the way some other industries publish one. Delta’s public workflow is model-number and feature lookup, not public serial-number decoding — the safest approach is “date or generation clue leads to a model or valve family, which leads to a parts diagram,” not “serial number leads directly to a part number.” Delta RP19804 Treat any claimed “Delta YYYY production-week” decoder you find online as unverified unless Delta’s own support page or a representative confirms it for your exact product family. Delta

For comparison, the other major brands run similar but distinct workflows. Pfister’s identification starts with an eight-character model code (something like F-529-7AYY), then uses category and finish filters and an “Installation & Support” section to reach the parts diagram; if the cartridge is already out, Pfister lets you search by part number or appearance and compare thumbnails and dimensions directly. Pfister Kohler’s service-parts page runs a similar identify-then-diagram-then-part sequence, and also offers Kohler Scout, a photo-upload identification tool still marked as beta. Kohler

Moen’s “Identify My Product” page is the manufacturer-preferred starting point, and Moen itself warns that similar-looking shower and faucet families can use different cartridges — so confirm through Moen’s own tool before buying. Moen American Standard’s parts-support page is the equivalent preferred starting point for that brand, since family names, trim names, and cartridge numbers can differ from what a retailer listing shows.

How to Identify Your Delta Faucet: Quick Decision Tree

Work through these in order — from fastest to most involved:

1. Do you have a model number from the box, manual, or a supply-line tag? Enter it into Delta’s parts search and you’re done. Delta
2. No model number, but the faucet is visible and undamaged? Compare the handle shape, spout profile, finish, and deck plate against Delta’s product galleries, or run Delta’s guided product identifier.
3. Still unsure, and you’re comfortable shutting off the water? Pull the handle and trim sleeve, then read the cartridge cap color — white points to the older RP19804 family, gray points to the newer RP46074 family. Delta RP19804
4. Cartridge markings unclear or the part looks non-standard? Photograph it and check whether it matches a specific documented part like RP4993 (seats and springs) rather than guessing at a universal substitute. Delta RP4993
5. None of the above gets you a confirmed match? Move to the fallback steps below before ordering anything.

If You Still Can’t Match It

Take clear photos before you do anything else: the whole faucet, the handle straight-on, the underside under the sink, any supply-line labels, the aerator, the escutcheon, the removed cartridge, and any stamped markings. This is exactly the input Kohler’s Scout tool and Pfister’s cartridge-matching workflow are built around, and it works the same way if you email Delta’s support team directly. Kohler Pfister

Only use a universal or aftermarket part when the listing explicitly names the brand, part family, or an exact dimensional match — Delta’s own RP4993 listing, for example, names it as a specific service part for a specific symptom (a spout drip when water is off, on non-DST faucets), not a generic substitute. Delta RP4993 Delta Parts Finder

And know when identification is telling you to stop chasing parts and replace the fixture instead. Replace the whole faucet when the finish is failing, the trim is discontinued, or the valve body can’t accept the trim family you want — Delta itself confirms that a pre-2006 Monitor 1300/1400 valve cannot be converted to a newer 17-series dual-control trim without replacing the valve body entirely. Delta RP19804 If you’ve bought the wrong cartridge twice, the cost of a third attempt is usually past the point where replacement makes more sense.

When to Call a Plumber for Identification

Some situations are worth paying for rather than fighting through. Call a plumber when the cartridge has to come out just to identify the generation, when the shutoff valves are seized, when the trim screws are corroded in place, or when you genuinely can’t risk breaking the bonnet nut or valve body trying to get a look. Delta’s own RP19804 support answer specifically warns against prying a cartridge out with a screwdriver and instead gives a controlled removal sequence after the water is off — that’s a sign the manufacturer expects this step to go wrong for DIYers often enough to call it out. Delta RP19804

A short plumber visit can also be cheaper than guessing wrong on a trim kit. Delta confirms that an old 1300/1400 valve can accept a current T13/T14 trim only if you keep using the RP19804 cartridge — it cannot use the new cartridge that ships in the box with those trims. Buy the wrong kit based on a misread valve, and you’ve paid for parts you can’t use. Delta RP19804

On cost: HomeAdvisor’s 2026 data puts typical professional plumbing projects at $182 to $500, with trip fees of $50 to $300, service-call fees of $100 to $250, and hourly rates commonly between $45 and $200. HomeAdvisor A quick identification-only visit will usually land closer to a local service-call minimum than a full project total — budget roughly $100 to $250 in most markets rather than assuming a flat number, since that figure varies by region.
