Dripping Faucet: Repair the Cartridge or Replace It?

Why the drip happens here more than elsewhere
A faucet drips because the parts that seal off the water, a cartridge, a washer, or a valve seat, have worn to the point that they no longer close completely. In Westminster this happens sooner than the fixture's label would suggest, because the moderately hard water carries mineral grit that works at those sealing surfaces every time the handle turns. The same water leaves scale in aerators and stiffens cartridges, which is why local faucets lose flow and start dripping ahead of schedule.
That matters for the decision because it means the drip is usually a normal wear item, not a defect, and often an inexpensive one to address. A steady drip also wastes a real amount of water over a month, and a faucet leaking at the base can quietly damage a vanity or countertop from underneath, so it is worth resolving rather than living with.
The question that decides repair versus replace
The deciding question is simple: is this a quality faucet or a cheap one? A well-made faucet with a worn cartridge is worth repairing, because a fresh cartridge or valve seat restores it and the body has plenty of life left. A cheap fixture that has corroded internally is usually better replaced, because rebuilding it costs nearly as much as a new one and does not last. A plumber can tell you which yours is rather than defaulting to selling a replacement.
Low flow is a related but separate issue with an easy answer. When just one faucet has weak flow while the others are fine, the culprit is almost always a scaled aerator, the small screen at the tip, and cleaning or replacing it fixes the flow in minutes. It is worth ruling that out before assuming a faucet needs any deeper repair at all.
The upgrade worth doing while the sink is apart
Whether you repair or replace, the best moment to deal with the shutoff valves under the sink is while it is already apart. After years of mineral-heavy water, tired angle stops often refuse to seat all the way, and the time you find that out, mid-emergency, when shutting one fixture off in a hurry is precisely what you need, is the worst moment for it. Swapping tired supply lines and shutoffs alongside a faucet is a small add-on that saves a real headache later.
This is also what separates a lasting new-faucet install from one that joins the drip list. Sound supply connections that will not weep, working shutoffs, and no cross-threaded fittings are what keep a new fixture reliable on hard water that will test every seal. Doing it properly the first time is cheaper than coming back to it.
How a modern faucet actually seals
Understanding why faucets drip makes the repair-or-replace call easier. Most modern faucets seal with a cartridge, a replaceable unit inside the faucet body that controls flow and temperature and does the actual work of shutting the water off. When you turn the handle to off, the cartridge presses a sealing surface closed. Over years, mineral grit from hard water scores that surface and stiffens the cartridge, until it no longer closes completely and a drip begins. That is wear, not breakage, which is why a fresh cartridge so often restores a faucet fully.
Older faucets use a rubber washer against a valve seat instead, and there the washer is the wear part. Either way, the sealing components are designed to be serviced, which is the whole reason a quality faucet is worth repairing rather than discarding. A plumber who opens the faucet can see immediately whether it is a simple worn-part repair or a body that has corroded past saving, and tell you which without guessing.
When replacing the whole fixture is the smarter call
Repair is not always the right answer, and pretending it is would cost you money too. A cheaply made faucet whose body has corroded internally, one where the cartridge is seized into a pitted housing, or a fixture so old that parts are no longer available, is usually better replaced than rebuilt, because the rebuild costs nearly as much and does not last. The same is true when you simply want a different fixture; there is no sense repairing something you are about to change.
The honest framing is that a good faucet with a worn cartridge is a repair, and a failing cheap one is a replacement, and the plumber should tell you which you have rather than defaulting to the more profitable option. Whichever it is, dealing with the tired shutoff valves under the sink at the same time, while everything is already apart, is the small step that keeps the next few years drip-free on water that tests every seal.
What your faucet is telling you
- Weak flow from one faucet: usually a scaled aerator, a quick fix
- Steady drip when off: a worn cartridge, washer or valve seat
- Leak at the base of the spout: internal seals, worth repairing promptly
- Stiff, grinding handle: mineral buildup in the cartridge
- Old shutoff that will not fully close: replace it while the sink is apart
Questions
Common questions
Is a small drip really worth fixing?
Yes. It wastes a surprising amount of water over a month, and a drip at the base can rot a vanity from underneath. On a quality faucet it is usually a quick, inexpensive cartridge repair.
One faucet has weak flow but the rest are fine. Why?
Almost always a scaled aerator, the small screen at the tip that catches mineral buildup from the hard water. Cleaning or replacing it usually restores the flow quickly, no deeper repair needed.
Why does the same faucet drip again a year later?
Usually because the hard water has worn a new cartridge or washer the same way it wore the last one. A quality faucet still makes repair worthwhile, and a whole-house softener slows the wear, but on hard water sealing parts are a periodic service item.
Can I replace a faucet cartridge myself?
A confident do-it-yourselfer often can, provided the water is shut off at the fixture and the correct replacement cartridge is matched to the faucet model. The two things that trip people up are seized cartridges that will not come out of a hard-water-scaled body without the right tool, and old shutoff valves that will not fully close so the water can be stopped. If either of those is the case, it becomes a job worth handing to a plumber rather than fighting.
