A faucet dripping once per second wastes over 3,000 gallons a year — and the sound alone is enough to drive anyone insane. The good news: most leaky faucets are fixed with a $5 part and 30 minutes, and you don’t need to be handy. You just need to know which type of faucet you have.
This guide covers the four faucet types, the fix for each, and the exact steps. Let’s stop that drip today.
How Do I Fix a Leaky Faucet Without Calling a Plumber? Identify Your Faucet
There are four types: compression (two separate hot/cold handles you twist multiple turns), ball (single handle, common in kitchens, often Delta), cartridge (single handle that goes up/down and side to side), and ceramic disc (single lever over a wide cylindrical body — the modern, expensive-feeling type). The fix differs for each, so identification comes first.
Compression faucets — the old-school kind — leak because of worn rubber washers. This is the easiest and cheapest fix: a washer costs pennies. Ball faucets leak from worn springs, seats, or the ball itself; a $15-$20 repair kit has everything. Cartridge faucets need the cartridge replaced ($15-$40). Ceramic disc faucets rarely leak, but when they do, the seals need replacing or the whole cylinder gets swapped.
Before you start: shut off the water. There are shutoff valves under the sink — turn both clockwise. No valves? Shut off the main. Then open the faucet to drain remaining water and plug the drain with a rag so tiny screws don’t vanish into the plumbing abyss. Every plumber has a story about the screw that got away; don’t star in yours.
The Repair: Step by Step
For compression faucets: remove the handle (unscrew the cap, remove the screw), unscrew the packing nut with a wrench, pull out the stem, and replace the washer at the bottom plus the O-ring on the stem. Reassemble in reverse. If the brass valve seat inside looks rough or pitted, replace it too — a $3 seat wrench and new seat take five minutes and prevent the new washer from failing fast.
For ball faucets: buy the repair kit matching your brand. Remove the handle, unscrew the cap, and lift out the ball, seats, and springs. Replace all of them — the kit is cheap, and replacing one worn part while leaving another is false economy. A drop of plumber’s grease on the new parts helps everything seat properly.
For cartridge faucets: remove the handle and retaining clip or nut, note the cartridge’s orientation (take a photo!), pull it straight out — pliers help — and slide the new one in exactly the same way. For ceramic disc: remove the handle, unscrew the cylinder, replace the rubber seals on the bottom, and reassemble. In all cases, turn the water back on slowly and check for leaks before celebrating.
Tools You'll Need (Probably Already Own Most)
The list is short: adjustable wrench, Phillips and flathead screwdrivers, pliers, and plumber’s grease. The only specialty items are the replacement parts — washers, O-rings, cartridges, or a repair kit — which is why identifying your faucet type first matters. Take a photo of the faucet and the parts to the hardware store; the plumbing aisle staff deal with this daily and will match parts in seconds.
Pro tip: if your faucet is a major brand (Delta, Moen, Kohler, American Standard), check the manufacturer’s website first. Many offer free replacement cartridges under lifetime warranties — Moen and Delta are famous for shipping free parts. A five-minute warranty claim can turn a $30 repair into a free one.
While you’re under the sink, look around. Water stains, corrosion on supply lines, or a damp cabinet floor are warnings of bigger issues. A leaky faucet is often the nudge that reveals aging supply lines — and catching those early is worth far more than the faucet fix. If you spot trouble beyond the faucet, our rundown of common plumbing problems will help you triage.
- Adjustable wrench, screwdrivers, pliers, plumber's grease
- Shut off water + plug the drain before starting
- Photo the disassembly — order matters on reassembly
- Replace washers AND seats on compression faucets
- Check manufacturer warranty — free cartridges are common
- Turn water on slowly; check for leaks before cleanup
When to Actually Call a Plumber
Call a pro if: the shutoff valves themselves leak or won’t turn (forcing them can burst a pipe), the faucet is corroded solid and won’t disassemble, you find water damage or mold under the sink, or the leak is in the wall/pipes rather than the faucet. Also call if you’ve replaced the parts and it still drips — the valve seat or body may be damaged beyond a simple fix.
Know the cost so you can decide: a plumber charges $150 to $350 for a faucet repair visit, versus $5 to $40 in parts DIY. If the faucet is 20+ years old and giving trouble, consider replacing the whole faucet ($100-$300 for a good one) rather than nursing it along — sometimes the smart money is on new. The Family Handyman plumbing section has excellent diagrams for every faucet type if you get stuck mid-repair.
Preventing the Next Leak
Faucet washers and cartridges wear out — it’s physics, not failure. But you can dramatically extend their life. The biggest factor is water pressure: pressure above 80 PSI hammers washers, cartridges, and supply lines throughout the house. A $10 pressure gauge on a hose bib tells you where you stand; if you’re over 80, a pressure regulator ($200-$400 installed) protects every fixture and appliance in the home.
Water quality matters too: hard water’s mineral deposits chew through rubber washers and clog cartridges. If your fixtures constantly develop problems, consider testing your water hardness — a whole-house softener ($1,000-$2,500) extends the life of every plumbing component, plus your water heater, dishwasher, and washing machine. It’s a systems investment that pays across the whole house.
And the simple habits: don’t crank handles with gorilla force (the number one cause of premature washer death — firm closure, not maximum torque), fix drips promptly (a small drip becomes a worn seat, which becomes a bigger repair), and exercise your shutoff valves twice a year (turn them off and on — valves that sit for years seize when you need them most). Our guide to fixing running toilets covers the same wear-and-prevention principles for your other most-used fixture. An ounce of prevention really is worth a pound of plumber.
Stop the Drip Today
Identify your faucet type, shut off the water, swap the worn washer/cartridge/seals, and turn it back on slowly. Thirty minutes, under $40 in parts (often under $10), and you’ll save thousands of gallons a year. It’s the perfect first plumbing project — low risk, high satisfaction, and the silence afterward is glorious.
