Key takeaways
- How long do kitchen faucets last? Typical lifespan ranges by valve type and finish, the warning signs of wear, and a repair-or-replace worked example.
A good kitchen faucet commonly lasts around 15 to 20 years, while an inexpensive one may need attention within 5 to 10. That gap comes down to what is inside the faucet, what comes out of your tap, and how often the handle moves. This guide, written by our editorial team from published specifications, manufacturer documentation and general plumbing knowledge, explains the typical ranges, which parts fail first, how to read the warning signs, and how to decide between a repair and a new faucet. The figures here are rules of thumb, not guarantees, so always check the manual and warranty for your model.
Typical lifespan by faucet quality
No single number fits every faucet, because the materials differ so much. The table below summarizes the ranges people commonly quote. Treat them as ballpark figures that shrink in harsh conditions and stretch with care.
| Faucet build | Commonly cited lifespan | What usually limits it |
|---|---|---|
| Solid brass body, ceramic disc cartridge | 15 to 20 years or more | Finish wear, supply lines |
| Mid-range, brass or mixed body | 10 to 15 years | Cartridge wear, hard-water scale |
| Budget, zinc or plastic internals | 5 to 10 years | Cracked parts, peeling plating |
| Compression-valve classic | Body can last decades | Rubber washers every few years |
Notice that the body and the moving parts age on different clocks. A faucet can look fine on the outside while its cartridge is already worn, and the reverse is also true. That is why many faucets are repaired rather than discarded.
What decides how long a faucet survives
Five factors matter most. The first is body material: solid brass resists corrosion and cracking better than lower-cost alloys, though a product page does not always state it, so look for it in the specifications. The second is the valve. Ceramic disc cartridges are widely considered the most durable, ball valves are respectable, and older compression designs depend on soft washers that wear out on a regular schedule.
Third is water chemistry. Hard water leaves scale that clogs aerators and scores cartridge surfaces. Water with a high chlorine level or low pH can slowly attack seals and finishes. If you have a water report or a home test kit result, it helps to know where you stand.
Fourth is how hard the faucet is used. A busy family kitchen can see the handle and spout moved dozens of times a day, and a pull-down hose is retracted and extended just as often. Fifth is cleaning. Abrasive pads and harsh chemical cleaners can strip protective finishes, while a soft cloth and mild soap usually do no harm.
Parts that tend to fail first
Most faucet problems start in a handful of small parts. Knowing the order makes diagnosis easier.
- Aerator: the screen at the spout tip clogs with mineral debris, which reduces flow or splits the stream. It is cheap and often removable by hand.
- O-rings and seals: these dry out or tear, causing drips at the base or around the spout swivel.
- Cartridge or valve: wear here causes drips from the spout, stiff handles or loss of temperature control.
- Pull-down hose and diverter: kinks, cracks and sticking diverters show up as weak spray or leaks under the sink.
- Supply lines: flexible lines age separately from the faucet and can corrode or fray.
- Finish: peeling, pitting or dull patches appear last and are usually cosmetic, but can signal a failing plated surface.
Warning signs that a faucet is wearing out
Some signs are urgent and others are simply annoying. A steady drip from the spout when the handle is off suggests a worn cartridge or seat. Water pooling around the base or inside the cabinet points to a leaking seal, hose or connection, and deserves quick attention because moisture can damage the cabinet. Handles that feel gritty, wobble, or no longer return to the same position often indicate internal wear or loosening parts.
Falling water pressure at only one faucet, while other taps run normally, usually means a clogged aerator or a failing cartridge. Hot and cold that no longer blend smoothly can mean a worn mixing valve. Green or white crusty deposits on fittings suggest slow leaks and corrosion. A single sign may be a small job, but several at once, especially on an older faucet, often signal that replacement will be easier than chasing each issue.
Repair or replace: a worked example
Here is a simple way to decide, using stated assumptions rather than real prices. Suppose your faucet is 12 years old, its body is solid and shiny, and it drips from the spout. Assume a replacement cartridge costs a small fraction of a new faucet, and you are comfortable with basic tools.
- Identify the model from the manual, a stamp on the body or a label under the sink.
- Check whether the manufacturer still sells the matching cartridge. If it does, repair is likely sensible.
- Look at the finish and body. If they are pitted, corroded or cracked, repair buys little time.
- Add up the likely parts, such as a cartridge, O-rings and an aerator, and compare with a comparable new faucet.
- Consider how long you plan to stay in the home and whether you want a different style or features.
If the parts are available and the body is sound, repairing a 12-year-old faucet commonly extends its life by several years for little money. If the cartridge is discontinued, or the faucet has several problems, replacing it is usually the cleaner choice.

How to make a faucet last longer
Small habits add up. Descale the aerator every few months if your water is hard, by unscrewing it and soaking it in white vinegar for a short time, then rinsing. Avoid forcing the handle past its stop. Wipe the finish with a soft cloth and mild soap, and skip abrasive pads and strong cleaners. Check under the sink every so often for damp spots, since small leaks are easiest to fix early.
When you buy or replace, choose a faucet whose manufacturer sells spare cartridges and offers a clear warranty. Those two details matter more than most marketing claims. Keep the manual and the model number somewhere easy to find, because identifying the exact model is the hardest part of ordering parts later.
Common myths about faucet lifespan
One myth is that a higher price always means a longer life. Price often reflects styling and features, so check the body material, valve type and warranty rather than assuming. Another is that a drip is harmless. A slow drip wastes water, can stain the sink, and may point to a part that will worsen. A third is that every leak needs a whole new faucet, when many are fixed with a seal or cartridge. Finally, a shiny finish does not prove the internals are healthy, and a worn finish does not always mean the faucet is finished.
When to call a plumber
A professional is sensible if you cannot shut off the water supply, if shutoff valves under the sink are stuck or leaking, or if you see corrosion on pipes rather than only on the faucet. Call one too if a repair does not stop the leak, if you are unsure how to reassemble the faucet, or if water has already reached the cabinet or floor. Always turn off the water before you begin work, and follow the manufacturer’s instructions for your model.

Frequently asked questions
How many years should a kitchen faucet last?
A well-made faucet with a solid brass body and a ceramic disc cartridge commonly lasts 15 to 20 years in a home, while budget models with zinc bodies and plated finishes often wear out sooner. Water hardness, daily use and cleaning habits all shift that range. Treat these numbers as rough expectations, and check the warranty terms for the model you own.
Is it worth repairing a 10-year-old kitchen faucet?
Often yes, if the body is sound and the problem is a worn cartridge, O-ring or aerator. These parts are usually inexpensive compared with a new faucet. Repair makes less sense when the body is pitted or cracked, the finish is peeling, or replacement parts are no longer sold. Compare the cost of the parts and your time with the price of a comparable new faucet.
Does hard water shorten faucet life?
It can. Dissolved minerals form scale inside aerators, cartridges and spray heads, which restricts flow and can make handles stiff or leaky. Regular descaling of the aerator and sprayer, and wiping spots from the finish, often slows this. A whole-house or under-sink softening or filtration setup may also help, but check what suits your water supply and plumbing.
Which type of faucet valve lasts longest?
Ceramic disc cartridges are widely regarded as among the most durable because the hard discs resist wear and mineral scoring. Compression valves use rubber washers that wear every few years but are simple and cheap to fix. Ball and cartridge designs fall in between. The valve type is usually listed in the product specifications or manual.
Should supply lines be replaced along with the faucet?
Many plumbers suggest it, because flexible supply lines age separately and are inexpensive next to a leak or water damage. Look at the braiding for fraying, rust or bulges, and at the connections for crusty deposits. If your faucet kit includes new lines, using them is a reasonable precaution. Always shut off the water first and follow the manufacturer’s instructions.
