How to Fix a Dripping Faucet (and When to Stop)
Most dripping faucets come down to a worn washer, O-ring, or cartridge, and on many faucets that is a genuinely doable home repair if you shut off the water first and take the parts to match them. A steady drip is worth fixing quickly, because it wastes a surprising amount of water and, in Frederick's hard water, the minerals keep degrading the worn seal faster.
That said, there is a clear line between a repair worth doing yourself and one where a plumber saves you money by not turning a small job into a bigger one. Here is how to fix the common cases and how to know when to stop.
What makes a faucet drip
A faucet drips when the part that is supposed to seal off the water no longer seats properly. In older compression faucets that is usually a worn rubber washer or seat. In newer single-handle faucets it is typically a worn cartridge or O-ring. Frederick's hard water speeds this up, because mineral deposits build on the moving parts and wear the seals, which is why faucets here can need attention a bit sooner than in soft-water areas.
Identifying your faucet type is the first step, because it determines which part to replace and whether the repair is straightforward or fiddly.
The DIY fix worth trying
For a standard drip, the process is consistent: shut off the supply valves under the sink, plug the drain so no small parts vanish, and disassemble the handle to reach the washer, O-ring, or cartridge. Take the worn part to the store to match it exactly rather than guessing, reassemble, and test. On a common faucet in good condition, this is an afternoon job with basic tools.
One Frederick-specific tip: expect mineral buildup on the parts, and clean it off rather than forcing anything. Scale can make a cartridge feel stuck when it just needs cleaning.
Keep in mind that a slow drip and a spraying or wildly leaking faucet are different problems. A drip from the spout is usually a worn seal you can address. Water leaking from around the base of the handle or under the sink points to O-rings or supply-line connections instead, and a faucet that sprays erratically may have a scaled aerator that just needs cleaning. Matching the symptom to the part saves you from replacing the wrong thing.
- Shut off the under-sink supply valves first
- Plug the drain so small parts cannot fall in
- Take the worn part to match it exactly
- Clean mineral scale off parts rather than forcing them
- Test at low pressure before fully reassembling
You do not have to read to the end. Call and talk it through with a licensed local plumber.

Stop if the shutoff valves under the sink will not turn or leak when you use them, because a seized valve is its own repair and you do not want to be stuck with no way to stop the water. Stop if the faucet is old and corroded to the point that parts are seizing, if the drip continues after you replace the obvious parts, or if you find corrosion on the supply lines themselves.
These are the moments where a plumber saves money rather than costs it, because the alternative is a snapped valve or a stripped fitting turning a drip into a flood on a Saturday night. Knowing when to hand it off is part of doing it right.
Repair or replace the faucet
If a faucet is relatively new and the fix is a washer or cartridge, repair it. If it is old, corroded, and has needed several repairs already, replacing it is often the better spend, especially given that a new faucet with modern ceramic-disc internals stands up to hard water better than worn older hardware.
The honest read is that a single drip on a decent faucet is a repair, while a faucet that keeps failing in Frederick's water is telling you it is near the end. A plumber can make that call quickly and install a replacement that lasts.
| Situation | DIY-friendly? | Better move |
|---|---|---|
| Worn washer or cartridge, good faucet | Yes | Match the part and replace it |
| Under-sink shutoff seized or leaking | No | Call before forcing anything |
| Drip persists after new parts | No | Plumber diagnoses the real cause |
| Old faucet, repeated failures | Sometimes | Replace with hard-water-friendly unit |
Faucet Repair questions, answered
Why does my faucet keep dripping even after I replaced the washer?
Often the seat the washer presses against is worn or scaled, or the faucet is a cartridge type where the washer was not the real problem. Frederick's hard water can also leave deposits that prevent a clean seal. If a new part does not fix it, the cause is elsewhere and worth a professional look.
Is a dripping faucet really worth fixing right away?
Yes. A steady drip wastes a meaningful amount of water over a month, which shows on a metered bill, and in hard water the worn seal only degrades faster. It is a small fix that pays for itself and prevents a slow drip from becoming a steady stream.
Can hard water damage my faucets?
It does not destroy them, but it accelerates wear on the internal seals and leaves mineral deposits on moving parts, which is why faucets in Frederick may need repair a little sooner. Modern ceramic-disc faucets handle hard water better than older washer-style ones.
When should I just replace the faucet instead of repairing it?
When it is old and corroded, when parts are seizing, or when it has needed repeated repairs. At that point a new faucet, ideally one built for hard water, costs less over time than continuing to patch worn hardware.
Why is water leaking from the base of my faucet, not the spout?
A leak at the base of the handle rather than a drip from the spout usually means worn O-rings inside the faucet body, not the washer or cartridge that causes spout drips. It is still often a repairable part, but a different one. If the leak is under the sink instead, check the supply-line connections, which can loosen or corrode over time.
