Why Your Faucet Keeps Dripping (And How to Actually Fix It)
A dripping faucet is rarely fixed by tightening the handle harder. Here's what's actually causing the drip internally, and when it's worth repairing versus replacing the whole fixture outright.
Why tightening the handle doesn't fix it
A dripping faucet is almost always caused by a worn internal part, a cartridge, O-ring, or washer depending on the faucet's design, that no longer creates a complete seal when the faucet is off. Tightening the handle harder doesn't address that worn part and can actually accelerate wear on the mechanism, making the eventual repair more involved than it needed to be.
Identifying which type of faucet you have
Compression faucets, common in older homes, use a rubber washer that compresses against a valve seat and are usually identified by needing to turn the handle multiple times to fully shut off. Cartridge, ball, and ceramic disk faucets, more common in newer installations, use different internal mechanisms and often shut off with a quarter turn or a single lever motion. Knowing which type is installed determines which specific part is likely worn and needs replacing.
The actual repair, in general terms
Repair involves shutting off the water supply to that specific fixture, disassembling the faucet handle and stem, and replacing the worn cartridge, washer, or O-ring with an exact match for that faucet's brand and model. Cartridges in particular are brand and often model-specific, which is why matching the exact part matters more than it might seem for what looks like a simple, generic repair.
When repair no longer makes sense
A faucet under about 10 years old with a single failed part is almost always worth repairing. Beyond that age, especially with visible mineral buildup inside the fixture, a finish that's worn or pitting, or a model old enough that matching parts is difficult to source, replacement is often the more practical and cost-effective path rather than continuing to chase repairs on an aging fixture.
Preventing the next drip
Avoiding excessive force when turning a faucet off, even when it seems to need it, and periodically cleaning the aerator to prevent mineral buildup from restricting flow both extend a faucet's working life. Neither prevents eventual wear entirely, since internal parts do wear out over normal use regardless, but both meaningfully slow the timeline.
A note on matching finishes when replacing a faucet
If only one faucet in a bathroom or kitchen is being replaced while surrounding fixtures, towel bars, cabinet hardware, stay the same, matching the existing finish, chrome, brushed nickel, matte black, keeps the space looking intentional rather than mismatched. This is a purely aesthetic consideration, not a functional one, but it's worth thinking about before purchasing a replacement based on price or features alone.
A note on smart and touchless faucets
Touchless and smart faucets have become more common in kitchen renovations, and while they add convenience, they also add electronic components, typically a battery pack or low-voltage transformer, that introduce a different kind of potential failure than a standard mechanical faucet. Anyone considering this upgrade should factor in that a touchless faucet issue sometimes involves troubleshooting electronics rather than just the standard cartridge or washer replacement covered above.

Dripping Faucet Questions
Can I fix a dripping faucet myself?
For someone comfortable with basic tools, yes, shutting off the supply valve and replacing a cartridge or washer is a manageable task, provided the exact replacement part is matched correctly.
Why does my faucet drip more at certain times of day?
Water pressure fluctuations throughout the day can make a marginal seal fail more noticeably during low-usage periods, like overnight, even though the underlying worn part is a constant issue.
Is a dripping faucet actually costing me money?
Yes, a faucet dripping once per second can waste over 3,000 gallons a year, a real and avoidable cost on the water bill.
How do I know which cartridge my faucet needs?
The faucet's brand and model, often printed somewhere on the fixture or in original documentation, determines the exact cartridge needed. A technician can also identify it during a repair visit.
Can hard water make a faucet drip more often?
Yes, mineral buildup on internal seals and cartridges accelerates wear, which is one more reason a dripping faucet may recur faster in areas with harder water.
Is a slow drip really worth calling about, or should I just live with it?
Given the wasted water and the risk of the internal parts wearing further, it's worth addressing sooner rather than later, even though it's never an emergency.
Do outdoor faucets need the same repair approach as indoor ones?
Generally yes, though outdoor faucets in this coastal area also contend with salt-air corrosion on top of normal internal wear, worth checking both factors during a repair.
Can a faucet leak from the base rather than the spout?
Yes, this usually points to a worn O-ring at the faucet's base connection rather than the internal cartridge, a different and often simpler repair than a spout drip.
Is it normal for a brand-new faucet to drip slightly at first?
A very minor drip immediately after installation sometimes resolves as components settle, but a persistent drip on a new fixture is worth addressing under warranty rather than assumed normal.
Can a faucet drip be caused by household water pressure being too high?
Yes, unusually high water pressure can accelerate wear on faucet seals and cartridges across every fixture in the house, worth checking if drips are happening on multiple faucets at once.
