That drip...drip...drip sound at 2 AM is enough to drive anyone crazy. Honestly, I remember lying awake staring at the ceiling, calculating how many gallons I was wasting before finally tackling it. Fixing a leaky faucet seems daunting, but it's usually simpler than you think. Let's cut through the confusion and get straight to practical solutions.
Why That Leaky Faucet Costs More Than You Think
Turns out that little drip is sneaky expensive. The EPA says a faucet leaking once per second wastes over 3,000 gallons yearly. At my local water rates, that's about $70 down the drain annually. But the real kicker? Mineral buildup from slow drips wrecks finishes faster. My neighbor ignored his kitchen leak for a year and ended up replacing the whole fixture.
| Leak Speed | Gallons Wasted Monthly | Potential Annual Cost* |
|---|---|---|
| 1 drip per second | 259 gallons | $70-$100 |
| Steady stream (toothpick width) | 10,000 gallons | $250-$350 |
*Based on average US water/sewer rates of $0.0025/gal
What Kind of Faucet Do You Have?
Most leaks happen because we grab the wrong parts. All faucets aren't built the same - I learned this hard way when I bought cartridge parts for my compression faucet. Waste of $12 and an hour.
Compression Faucets
Common in older homes. You'll feel resistance when turning off. Leaks usually mean worn washers. Easy fix once you wrestle off that stubborn handle (try wrapping duct tape around it for grip).
Cartridge Faucets
Single handle, moves up/down and side-to-side. Handle usually has a decorative cap hiding the screw. Leaks often require cartridge replacement. Pro tip: take photos during disassembly.
Ball Faucets
Single handle controlling a rounded ball mechanism. Prone to multiple leak points. Requires special plastic wrench included in repair kits.
Ceramic Disc
Modern, expensive faucets. Minimal moving parts but if they fail, you're often buying a new unit. When my Moen disc failed after 8 years, repair cost $45 vs $200+ for replacement.
Essential Tools You'll Actually Use
Forget those 20-piece plumbing kits collecting dust. Here's what you really need:
- Adjustable wrench - 8" size works for most jobs
- Screwdrivers - Phillips #2 and flathead
- Allen wrench set ($5 at hardware stores)
- Needle-nose pliers for tiny parts
- Plumber's grease - prevents sticking
- Bowl or container for parts
- Old toothbrush - cleaning mineral deposits
The brand debate? Honestly, I've had Harbor Freight wields last 10 years. Don't overspend unless you're doing daily plumbing work.
Step-by-Step Repair Guide
Getting Inside Your Faucet
First obstacle - removing the handle. Look for hidden screws under decorative caps. No visible hardware? Try gently prying off the handle with flathead screwdriver wrapped in cloth. Works 80% of time.
Diagnosing the Leak Source
| Leak Location | Likely Culprit | Fix Difficulty |
|---|---|---|
| Spout drip when closed | Worn washer or cartridge | Easy |
| Leaking around base | Faulty O-rings | Moderate |
| Water under sink | Supply line issues | Advanced |
Replacing Key Components
Bring old parts to hardware store - sizes vary wildly. Cartridge replacements? Buy brand-specific kits ($8-$25). Washers/O-rings often come in variety packs ($4).
When installing new washers, apply plumber's grease lightly. Don't overtighten! Snug plus quarter-turn prevents cracking plastic components.
Where DIY Goes Wrong
After helping neighbors fix botched repairs, here's the common disasters:
- Cross-threading cartridge housings - turns $10 fix into $75 replacement part
- Forgetting O-ring placement - causes mysterious leaks 2 days later
- Over-tightening connections - cracks porcelain sinks ($300 mistake)
- Not cleaning mineral deposits - new parts fail prematurely
My personal fail? Trying to fix a leak without closing valves fully. Got soaked and slipped on the wet floor. Lesson learned.
When to Call a Professional Plumber
While fixing a leaky faucet is usually DIY-friendly, call pros when:
- Water leaking inside walls or floorboards
- Rusted bolts that won't budge (they'll torch them carefully)
- Multiple leaks throughout house
- DIY attempt failed and now water sprays everywhere

Top Faucet Repair Questions
How do I fix a leaky faucet if I can't find the model number?
Take clear photos of entire fixture and internal parts. Hardware store associates can usually identify it. Worst case, buy universal cartridge/washer kits.
Can I just replace washers without turning off water?
Technically possible but incredibly messy and risky. Takes 30 seconds to close valves - save yourself the water damage headache.
Why does my faucet still drip after replacing cartridge?
Usually debris trapped in valve seat or forgotten O-ring. Disassemble again and clean thoroughly. I've found tiny pebbles from pipes causing this.
Is fixing a leaky faucet worth it for rental properties?
Absolutely - tenants waste water without penalty. Plus, unresolved leaks lead to costly damage deductions from security deposits.
What if replacement parts don't match exactly?
Most modern brands (Delta, Moen) have lifetime warranties. Call their customer service with photos - they'll often mail free parts even for older models.
Preventing Future Leaks
Extend your repair work with simple habits:
- Mineral control - install inline filter if you have hard water
- Gentle handling - don't crank handles shut with excessive force
- Annual maintenance - remove aerator, soak in vinegar
- Cold weather prep - dripping slightly during freeze warnings prevents pipe bursts
There you have it - everything I've learned from fixing countless drippy faucets over 20 years as a homeowner. The process becomes intuitive after your first repair. When someone asks "how do I fix a leaky faucet", you'll realize it's mostly about patience and organization. Now go silence that drip!
