That constant drip...drip...drip driving you nuts at 2 AM? I get it. My kitchen faucet started leaking last month right before hosting Thanksgiving. Water everywhere, guests arriving in hours, and that maddening sound. After replacing washers and cartridges more times than I can count over 15 years of home repairs, I've learned how to fix a dripping kitchen faucet isn't just about tightening screws – it's about knowing which screws to tighten.
Why You Should Fix That Drip Immediately
Most folks ignore a leaky faucet until it becomes a flood. Big mistake. One drip per second wastes 2,000+ gallons yearly – enough to fill a swimming pool. Your water bill skyrockets, and mineral buildup destroys fixtures. Worse, I've seen ignored leaks cause cabinet rot requiring $3,000+ repairs.
Honestly? Manufacturers don't make this easy. Last year I spent hours wrestling with a "quick-release" cartridge that needed three specialty tools. Cheap parts fail fast too – more on that later.
| Leak Speed | Annual Water Waste | Extra Annual Cost |
|---|---|---|
| 1 drip/sec | 2,082 gallons | $35-$100 |
| 5 drips/sec | 10,410 gallons | $175-$500 |
| Stream (toothpick thickness) | 34,000 gallons | $570-$1,600 |
Exactly What You'll Need to Fix It
Grab these tools before starting – nothing worse than being elbow-deep in plumbing when you realize you're missing something.
| Essential Tools | Optional But Helpful | Replacement Parts Kit Costs |
|---|---|---|
| Adjustable wrench | Basin wrench ($12) | Universal washers: $2-$5 |
| Allen wrench set | Flashlight/headlamp | Cartridges: $15-$45 |
| Screwdrivers (flat/Phillips) | Old toothbrush | Full rebuild kit: $25-$70 |
| Needle-nose pliers | Plumber's grease ($4) | New faucet: $150-$500 |
Pro Tip: Put a towel in the sink drain! Dropped screws vanish forever otherwise. Learned this after fishing a Moen set screw out of my garbage disposal...
What Type of Faucet Do You Have?
You can't fix what you can't identify. Kitchen faucets come in four main types – here's how to spot yours:
Compression Faucets (Old-school)
Two separate handles (hot/cold). You feel resistance when turning off. Common in pre-1980 homes. The repair is simple but they drip frequently.
Cartridge Faucets
Single or double handle. Smooth turning motion. Contains a replaceable cartridge. Most kitchen faucets today are this type.
Ball Faucets
Single handle controlling temperature/flow with a rounded cap. Prone to leaks from multiple points.
Ceramic Disc Faucets
Single lever, requires minimal force to operate. Extremely durable but expensive to repair.
Caution: Take photos before disassembly! Faucet guts resemble alien technology once dismantled.
Step-by-Step Repair Guide
Shut off water supply FIRST! Look under sink for shutoff valves. Turn clockwise until tight. Open faucet to drain residual water.
Fixing Compression Faucets
These leak from worn rubber washers – the easiest fix:
- Remove handle screw (often hidden under decorative cap)
- Unscrew packing nut counterclockwise
- Pull out valve stem
- Replace rubber washer at bottom ($1 part)
- Reassemble – don't overtighten!
I hate how these washers disintegrate every 2-3 years. Buy extras – they cost less than gum.
Fixing Cartridge Faucets
Leaks indicate worn cartridge seals. Brands like Delta and Moen have proprietary cartridges:
- Remove handle (may require Allen wrench)
- Unscrew retaining clip/nut
- Pull cartridge straight out
- Install identical replacement cartridge
- Apply plumber's grease to new cartridge seals
Stuck cartridge? Soak with vinegar overnight or tap gently with hammer/screwdriver handle.
When DIY Repair Isn't Enough
Sometimes fixing a dripping kitchen faucet isn't cost-effective. Replace the entire faucet if:
- Corrosion has eaten internal parts
- Multiple leaks appear simultaneously
- Manufacturer discontinued parts
- You've repaired it 3+ times already
My threshold? If repairs exceed 50% of replacement cost. Last year I wasted $80 on parts for a $150 faucet.
| Problem | DIY Repair Cost | Pro Repair Cost | Replacement Cost |
|---|---|---|---|
| Worn cartridge | $15-$40 | $120-$250 | $150-$500 |
| Multiple leaks | $30-$60 | $180-$350 | $150-$500 |
| Base corrosion | Impossible | $200-$400 | $150-$500 |
Real Questions People Ask About Dripping Faucets
Q: Will duct tape stop my faucet from dripping?
A: Temporarily maybe. Long-term? Absolutely not. You'll just create a soggy mess and delay proper kitchen faucet drip repair.
Q: My faucet only drips when certain handles are open – why?
A: That's a pressure imbalance issue, not worn parts. Install an anti-siphon valve or pressure regulator.
Q: Are expensive cartridges better than cheap ones?
A: Usually. Generic cartridges often last 6-18 months. OEM parts typically last 3-5 years. I learned this after replacing a $15 cartridge three times in two years.
Q: Water leaks from the handle base when turned on – fixable?
A: O-ring failure. Simple $2 fix if caught early. Ignore it and water damages internal components.
Critical Mistakes to Avoid
Watching DIY disasters taught me these pitfalls:
- Overtightening parts – causes hairline cracks that leak worse
- Using wrong replacement parts – measure twice, buy once
- Forgetting to turn off water supply – indoor floods aren't fun
- Installing cartridges backwards – yes, it happens
My worst fail? Cross-threading a cartridge housing. Had to replace the entire faucet body. Don't force anything!
Should You Repair or Replace?
Decision time. Repair if:
- Faucet is mid-range quality ($200+)
- Leak is recent and localized
- Parts are readily available
Replace if:
- Faucet is over 15 years old
- You've repaired it multiple times
- Corrosion is visible internally
- Water efficiency matters (new models use 30% less)
Consider water efficiency ratings – EPA-certified faucets save 700+ gallons annually. That's real money.
When to Call a Professional Plumber
Some situations demand experts:
- No shutoff valves under sink (requires main line shutdown)
- Significant corrosion or stripped threads
- Suspect lead pipes (pre-1970 homes)
- Leak persists after multiple repair attempts
My rule? If I spend over 2 hours without progress, I call Joe the plumber. Time has value too.
Learning how to fix a dripping kitchen faucet saves money and water. But be realistic – some battles aren't worth fighting. Whether replacing a $3 washer or installing a new faucet, remember: always turn off the water first. Happy plumbing!
