Quick answer: You can determine which Moen kitchen faucet you have by checking the handle design, spout shape, and the number and spacing of the mounting holes. The original box or manual often lists the model number; if missing, look for tags under the sink or markings on the faucet body, and compare those details to Moen’s series such as CA87530, 87014SRS or 7840 to confirm the exact model.
If you are asking which Moen kitchen faucet do I have, start with three things: the paperwork, the faucet itself, and the sink deck. The original box or manual usually shows the model number. If those are gone, look under the sink for a tag on the supply or pulldown hose, or for markings on the underside of the faucet body. Then note the handle style, the spout shape and how many holes the faucet uses. Even without an exact model number, these details tell you which cartridge family you need for a repair and which new faucet will fit your existing holes.
Once you know what is installed, the repair-or-replace decision gets much simpler. A drip or a stiff handle on a sound faucet is usually a cheap cartridge fix. A corroded body, a cracked spout or a finish you no longer like points to a new faucet, and matching your current hole layout keeps that swap to an afternoon job.
Quick diagnosis before you buy anything
Pin down the symptom first. Water dripping from the spout with the handle off, a handle that is hard to move, or poor hot and cold mixing almost always point to the cartridge. Water pooling around the base of the spout on a swivel model usually means worn O-rings. Low flow that affects only the spout often comes from a clogged aerator or a kinked pulldown hose.
Leaks under the sink are a different story. Check the supply line connections and the quick-connect fitting on a pulldown hose before you blame the faucet. A loose compression nut or a worn supply line is a simple fix and has nothing to do with the faucet's internal parts.
| Feature | Symptom | Fix or Replace |
|---|---|---|
| Cartridge | Dripping from spout or stiff handle | Replace cartridge (e.g., service kit 104630) |
| O-rings | Water pooling around base on swivel model | Replace O-rings |
| Aerator | Low flow from spout only | Clean or replace aerator |
| Supply line | Leaks under sink, loose nut | Tighten or replace supply line |
| Faucet body | Cracks, corrosion, peeling finish | Replace entire faucet |
| Hole layout | Mismatch with new faucet holes | Choose model matching holes (CA87530, 87014SRS, 7840) |
When a repair is enough
Most Moen single-handle and two-handle kitchen faucets use replaceable cartridges, so a drip or a stiff handle rarely means the whole faucet has to go. If the body is solid, the finish is in decent shape and the spout swivels without wobbling, replacing the cartridge, O-rings or aerator brings back like-new function for a fraction of the cost of a new faucet.
Pulldown problems are often fixable too. A wand that will not retract usually needs its weight repositioned on the hose, and a sprayer with weak or uneven spray often just needs its nozzles cleaned of mineral buildup. For light-commercial or heavily used fixtures, a service kit such as the 104630 can cover common wear parts. Confirm it matches your fixture's documentation before ordering.
Clear signs a replacement is the better buy
Replace the faucet when the body itself is failing. Hairline cracks, corrosion where the spout meets the base, or a leak that returns soon after a new cartridge all point that way. Pitting or peeling finish is cosmetic at first, but it tends to spread, and at that point you are fixing a faucet you will not be happy looking at.
Age and parts availability matter as well. If you cannot identify the faucet well enough to source the right cartridge, or the repair parts together approach the cost of a new faucet, replacement is the more sensible spend. The same goes for function: an old low-arc faucet with a separate side spray can be swapped for a high-arc pulldown that fills tall pots and rinses the whole sink.
Which Moen kitchen faucet do I have and what fits
Start with the series. Moen faucet lines have distinct handle and spout shapes, so compare your faucet with photos of current and past collections. The handle shape, whether the spout is a gooseneck or a curved low arc, and whether there is a side spray or a pulldown wand will usually narrow it down to a family. Search terms like Posi-Temp, M-CORE or Moentrol refer to Moen tub and shower valves, not kitchen faucets. If those names come up, you are looking at shower parts. Kitchen faucets keep their valve cartridge inside the faucet body, so the faucet and its cartridge are identified together.
Next, count the holes in your sink or countertop and measure the spacing. Common layouts are a single hole, three holes with handles spread 8 inches center to center, or four holes when a side spray is added. Holes are typically around 1-3/8 to 1-1/2 inches in diameter, and most faucets accept a deck up to roughly 2 inches thick. Check the spec sheet of the model you are considering for its exact limits. A single-hole faucet can usually cover a three-hole sink with a deck plate, but going the other way is not possible without plugging or adding holes.
Then look at connections. Most modern faucets attach to 3/8-inch compression shutoff valves, while some older installs use 1/2-inch fittings that need adapter supply lines. If your sink has four holes and you want to keep using all of them, a model with a side spray, such as the CA87530 Adler in chrome, keeps the layout intact. If you would rather consolidate to a pulldown, the 87014SRS Essie high-arc pulldown in spot resist stainless is a practical upgrade. Use its deck plate option where it applies and cover or plug any leftover holes. For a straightforward like-for-like swap on a simple single-handle low-arc setup, the 7840 Camerist in chrome is worth comparing against your current spout height and reach.
What to check before ordering
Before you order, confirm your hole count, spacing and deck thickness against the new faucet's spec sheet. Measure the clearance behind the sink to a backsplash or window so a high-arc spout or a back-tilting handle has room to move. Check that the spout reach lands near the center of your basin, and confirm your shutoff valve size so you have the right supply lines on hand. Make sure the shutoffs actually close fully, because a stuck valve can turn a one-hour install into a much longer job. Also check the flow rate on the spec sheet, which on kitchen faucets typically runs about 1.5 to 2.2 gpm depending on the model and local requirements.
Matching the old faucet to the new one
Identifying your Moen kitchen faucet comes down to the handle, the spout, the hole count and the connection size. With those four details, you can decide quickly whether a cartridge or O-ring repair will do or whether a new faucet makes more sense. If you replace, choose a model built for your existing hole layout. Keep a four-hole sink with a side-spray faucet like the CA87530, consolidate to a pulldown like the 87014SRS with a deck plate, or stay simple with the 7840 when a single-handle low arc already suits your sink.
