The American Standard M951483-0070A is a genuine 35mm cartridge and screw kit sold through American Standard’s official parts store for use in compatible single-handle kitchen faucets, including applications associated with the Soltura kitchen faucet line. Inside the faucet, this cartridge is the internal valve that controls water flow and, in mixing faucets, hot-and-cold blending when you move the handle.
When this part wears out, homeowners typically notice dripping at the spout, a handle that feels stiff or hard to turn, inconsistent water temperature, or leaking around the base of the handle. Not every one of these symptoms automatically means the cartridge has failed — worn seals, mineral buildup, or an unrelated supply-line issue can cause similar symptoms. Before ordering a replacement, it is worth confirming your exact faucet model and matching it against the manufacturer’s parts documentation.
What Is the American Standard M951483-0070A Cartridge?
A faucet cartridge is a self-contained valve unit that sits inside the body of a single-handle faucet. When you lift, lower, or turn the handle, the cartridge is what actually opens and closes the water path and — on faucets with hot and cold supply lines — blends the two together to the temperature you select. It is a different part from the outer handle, the decorative cap, or the faucet body itself; those are separate components that simply cover and operate the cartridge underneath.
The “35mm” in the product name refers to the cartridge’s diameter, a common sizing standard used across many single-handle kitchen and bathroom faucets from multiple manufacturers. Over years of use, the internal seals and moving surfaces inside a cartridge wear down from mineral deposits, repeated motion, and general age, which is why a cartridge that once operated smoothly can eventually start to drip, stick, or leak even though the rest of the faucet is in good condition.
Is M951483-0070A Compatible With the Soltura Kitchen Faucet?
The M951483-0070A cartridge and screw kit is listed on American Standard’s official parts store under Kitchen Faucet Parts, and it is documented by American Standard’s own retail listings as the 35mm cartridge used with the Soltura kitchen faucet. American Standard also sells a separate, dedicated handle kit specifically labeled for the Soltura kitchen faucet, which supports that Soltura is a line with its own documented replacement parts.
That said, American Standard’s kitchen faucet lineup includes multiple Soltura configurations (different finishes, spray options, and mounting styles), and a shared collection name does not guarantee that every unit built under that name uses an identical internal cartridge. Before ordering a replacement, compare your faucet’s exact model number and your existing cartridge with American Standard’s parts documentation for your specific unit, either through the official parts store or by contacting American Standard support directly. This extra step takes a few minutes and prevents ordering a part that looks similar but does not fit correctly.

Signs Your Soltura Faucet Cartridge May Need Replacement
Faucet Keeps Dripping
A worn cartridge can allow a small amount of water to pass even after the handle is fully closed, showing up as a persistent drip at the spout. Dripping can also come from a worn aerator seal or a failing supply valve, so it’s worth ruling those out if replacing the cartridge doesn’t fully resolve it.
Handle Is Hard to Turn
Stiffness when operating the handle is often tied to internal cartridge wear, but mineral buildup inside the cartridge or corrosion on the handle mechanism itself can cause the same symptom.
Water Temperature Is Difficult to Control
Since the cartridge is what blends hot and cold supply lines, a damaged cartridge can make it hard to land on a consistent temperature, causing the water to run too hot, too cold, or fluctuate unexpectedly.
Water Leaks Around the Handle
Moisture appearing at the base of the handle, rather than at the spout, often points to worn cartridge seals — though the exact source should be confirmed before ordering parts, since a loose handle assembly can look similar.
Flow Is Weak or Inconsistent
A failing cartridge can restrict flow, but a clogged aerator, partially closed supply valve, or kinked supply hose are common causes of the same complaint and are worth checking first since they’re simpler to fix.
How to Confirm the Cartridge Is the Problem
Step 1: Identify the faucet model. Look for a model number on the faucet documentation, packaging, or through American Standard’s model lookup tools.
Step 2: Check the manufacturer’s parts list. Compare the cartridge part number listed for your faucet model against M951483-0070A before purchasing.
Step 3: Observe the exact symptom. Note whether the issue is dripping, handle resistance, temperature control, handle-area leaking, or reduced flow, since this narrows down the likely cause.
Step 4: Check other possible causes. Inspect the aerator, supply valves, supply hoses, and connection points for looseness, debris, or wear before assuming the cartridge is at fault. If you notice water pooling under the sink rather than just at the faucet, it’s also worth ruling out unrelated sources like a garbage disposal leaking at the bottom.
Step 5: Verify the cartridge itself. Only after ruling out the simpler causes should you remove the handle and inspect or replace the cartridge.
What You Need Before Replacing the M951483-0070A
- Replacement M951483-0070A cartridge and screw kit
- Manufacturer-specific installation instructions for your exact faucet model
- A screwdriver (type depends on your faucet’s screws)
- A hex/Allen key, if your faucet’s handle uses a set screw
- An adjustable wrench, if needed for your faucet design
- A clean cloth
- A small container to hold screws and small parts
- A towel to catch drips
Tools required can vary by faucet model, so check your faucet’s documentation rather than assuming a single tool list applies to every Soltura configuration.
How to Replace the American Standard M951483-0070A Cartridge
Step 1: Shut Off the Water
Close the faucet’s dedicated shutoff valves, usually located under the sink. If your faucet has no accessible individual shutoffs, shut off the home’s main water supply instead.
Step 2: Open the Faucet
Turn the handle to release any remaining water pressure in the lines before beginning disassembly.
Step 3: Remove the Handle
Handle attachment varies by faucet model — some use a visible screw, others use a hidden set screw under a cap. Follow your specific faucet’s instructions rather than guessing at the location.
Step 4: Access the Cartridge
Depending on your faucet design, you may need to remove a decorative cap, retaining nut, or trim ring before the cartridge is exposed.
Step 5: Remove the Old Cartridge
Removal methods differ by faucet design — some cartridges lift straight out, others require a retaining clip to be removed first. If the cartridge resists, do not force it; mineral buildup or corrosion may be holding it in place.
Step 6: Compare Old and New Cartridges
Before installing the replacement, check that the size, shape, tab orientation, and seal placement match the old cartridge, and confirm the part number matches M951483-0070A.
Step 7: Install the New Cartridge
Seat the new cartridge in the correct orientation, following the alignment shown by the manufacturer’s instructions or the orientation of the original part.
Step 8: Reassemble the Faucet
Reinstall any retaining components, trim, and the handle in the reverse order they were removed.
Step 9: Turn the Water Back On Slowly
Open the shutoff valves gradually and check the connections and cartridge area for leaks before fully opening them.
Step 10: Test the Faucet
Run both hot and cold water, check flow strength, confirm smooth handle movement, and inspect for leaks at the handle and under the sink.
Common Mistakes When Replacing a Faucet Cartridge
- Buying a generic 35mm cartridge and assuming it will fit without checking the exact part number
- Assuming all 35mm cartridges are interchangeable across brands
- Skipping the water shutoff step
- Losing small screws or retaining clips during disassembly
- Installing the new cartridge backward or misaligned
- Damaging seals during removal or installation
- Forcing a stuck cartridge instead of addressing the buildup causing it to stick
- Not cleaning the cartridge housing before installing the new part
- Skipping the leak check after reassembly
- Over-tightening the retaining nut or handle screw
- Using a lubricant not rated for plumbing seals
The presence of “35mm” on a listing does not by itself confirm compatibility — the part number, tab layout, and seal design all need to match your specific faucet.
What If the M951483-0070A Cartridge Is Stuck?
A stuck cartridge is usually the result of mineral buildup, corrosion, or years of continuous use without removal. Damaged seals can also cause a cartridge to bind in place. Try gentle, steady pressure with an appropriate tool rather than aggressive force, since excessive force risks cracking the faucet body or damaging surrounding components. If the cartridge will not come free without risking damage to the faucet, it’s reasonable to bring in a professional rather than continue forcing it.
Can You Clean the Old Cartridge Instead of Replacing It?
Cleaning can sometimes help if the issue is caused by mineral deposits or debris interfering with smooth operation, and it’s a reasonable first step to try. However, cleaning will not restore a cartridge with worn or damaged internal seals, cracked components, or a persistent drip that returns shortly after cleaning.
Replacement is generally the better option when you’re dealing with:
- Damaged or torn seals
- A cracked cartridge housing
- Dripping that continues after cleaning
- Excessive wear from age
- A cartridge that has failed more than once in a short period
Genuine American Standard Cartridge vs. Generic Replacement
A genuine American Standard M951483-0070A cartridge is manufactured to the exact fit, seal quality, and material specifications of the original part, which supports a reliable seal and consistent operation over time. Genuine parts also stay eligible for American Standard’s product warranty and support programs, which is worth factoring in alongside upfront cost. Aftermarket or generic 35mm cartridges may work in some cases, but compatibility, seal material, and long-term durability can vary by manufacturer, and not all generic parts are covered under American Standard’s warranty support.
This isn’t a claim that aftermarket parts are inherently low quality — many perform well — but the number “35mm” alone doesn’t guarantee a proper fit or long-term reliability. Matching the exact part number and confirming compatibility with your faucet model matters more than the general size specification.
How Much Does an M951483-0070A Replacement Cost?
Total cost depends on several factors rather than one fixed number:
- The price of the cartridge and screw kit itself
- Shipping, if ordered online
- Any tools you don’t already own
- Professional labor, if you hire a plumber for the installation
- Additional seals or parts if other components also need replacing
- The scope of repair if the cartridge issue uncovered a larger faucet problem
For current pricing, check American Standard’s official parts store directly, since prices can change and vary by retailer.
Cartridge Replacement vs. Replacing the Entire Faucet
| Option | Best When | Advantages | Considerations |
|---|---|---|---|
| Replace cartridge | Faucet body and finish are in good condition | Lower cost and scope of repair | Requires a genuinely compatible cartridge |
| Repair other components | Problem is isolated to a seal, aerator, or connection | May avoid cartridge replacement entirely | Requires accurate diagnosis first |
| Replace entire faucet | Faucet body is damaged or problems keep recurring | Fresh fixture with no accumulated wear | Higher overall cost and full reinstallation |
If the faucet body, finish, and other components are otherwise in good shape, replacing just the cartridge is often the more practical and cost-effective route compared to replacing the whole faucet.
How to Maintain a Soltura Kitchen Faucet
- Avoid forcing the handle past its normal range of motion
- Clean the aerator periodically to prevent mineral clogging
- Address small leaks early before they worsen
- Keep mineral buildup under control with regular cleaning
- Follow American Standard’s specific care and cleaning instructions for your faucet finish
- Avoid abrasive cleaners that can damage the faucet’s finish
- Check supply connections periodically for early signs of leaking
- Use manufacturer-approved replacement parts when repairs are needed
When Should You Call a Plumber?
Consider professional help when:
- The water supply cannot be shut off cleanly
- The cartridge is stuck and won’t release without risking damage
- The faucet body itself appears cracked or damaged
- Water is leaking into the cabinet below the sink
- Supply line connections are leaking
- Replacing the cartridge doesn’t resolve the original problem
- You suspect hidden plumbing damage beyond the faucet
- You’re not comfortable disassembling or reassembling the faucet yourself

It is a genuine American Standard 35mm cartridge and screw kit sold through the official parts store for use in compatible single-handle kitchen faucets, including Soltura kitchen faucet applications. It controls water flow and temperature blending inside the faucet.
Is M951483-0070A a 35mm cartridge?
Yes, American Standard lists this part as a “35mm Cartridge & Screw Kit,” referring to the cartridge’s diameter, which is a common sizing standard across several single-handle faucet designs.
Is M951483-0070A compatible with Soltura kitchen faucets?
It is documented as the 35mm cartridge associated with Soltura kitchen faucet applications, but Soltura includes multiple faucet configurations. Confirm your exact model number against American Standard’s parts documentation before ordering.
How do I know if my Soltura faucet needs a new cartridge?
Common signs include persistent dripping, a stiff or hard-to-turn handle, inconsistent water temperature, or leaking around the handle base. Rule out the aerator, supply valves, and connections first, since they can cause similar symptoms.
Can I replace the M951483-0070A myself?
Many homeowners can replace it with basic tools and by following the manufacturer’s model-specific instructions. If the cartridge is stuck or the faucet requires disassembly you’re uncomfortable with, professional help is a reasonable option.
What causes a kitchen faucet cartridge to fail? Cartridges wear out over time due to mineral buildup, repeated handle motion, and general aging of internal seals. This gradual wear is normal and expected after years of regular use.
Can I clean the old cartridge instead of replacing it?
Cleaning can help with mineral buildup or debris causing stiffness, but it won’t fix worn seals or a cracked cartridge. If dripping returns shortly after cleaning, replacement is usually the better long-term fix.
Are all 35mm faucet cartridges interchangeable?
No. “35mm” refers only to diameter; the tab layout, seal design, and manufacturer-specific fit still need to match. Always confirm the exact part number rather than relying on size alone.
What should I do if the cartridge is stuck?
Try gentle, steady pressure rather than force, since excessive force can crack the faucet body. If it won’t release safely, it’s reasonable to call a plumber rather than risk damaging the fixture.
Should I replace the cartridge or the entire faucet?
If the faucet body and finish are otherwise in good condition, replacing just the cartridge is usually more practical and cost-effective. Full faucet replacement makes more sense if the body is damaged or problems keep recurring.
Conclusion
The American Standard M951483-0070A is a specific 35mm cartridge and screw kit sold through American Standard’s official parts store, documented in connection with Soltura kitchen faucet applications. Because Soltura covers multiple faucet configurations, it’s worth matching your exact model number to the manufacturer’s parts documentation before ordering. A worn cartridge can cause dripping, a stiff handle, temperature control issues, or handle-area leaks — but since other components can cause similar symptoms, proper diagnosis matters before assuming the cartridge is at fault. When the rest of the faucet is in good shape, replacing the cartridge is often more practical than replacing the entire fixture. Follow model-specific American Standard instructions during installation, and call a plumber if the cartridge is stuck or the repair becomes more involved than expected.
