A dripping faucet wastes around 3,000 gallons of water per year. Per year. That’s not a typo — that’s one leaky kitchen tap quietly padding your water bill while you sleep. And the fix? About four dollars in parts and forty minutes of your Sunday afternoon.
I’ve patched probably a dozen leaky faucets over the years — bathroom, kitchen, that weird utility sink in the basement nobody uses but somehow always drips. The first time, I was genuinely convinced I’d make everything worse. I didn’t. And if I managed it, you can too, because the truth about most faucet leaks is that they’re almost embarrassingly simple once you know what you’re actually looking at.
This guide is built for people who’ve never touched a faucet in their life. No plumbing background required. No exotic tools. Just a willingness to turn a few screws and stop hemorrhaging money — or, well, dripping it away.
What Type of Faucet Do You Actually Have?
This matters more than anything. A lot of “how to fix a leaky faucet” guides just… skip this part. They shouldn’t. The repair process is completely different depending on your faucet type.
Four main types exist: ball, cartridge, ceramic disc, and compression. Most faucets made before 1990 are compression — the ones with two separate handles you physically twist. Modern single-handle faucets are almost always ball or cartridge. Ceramic disc faucets tend to show up in higher-end kitchens and bathrooms, recognizable by their wide cylindrical body.
Not sure which you’ve got? how to identify your faucet type The quickest trick is to watch how the handle moves. Single handle that swings in an arc? Probably ball. Single handle that slides up/down or side-to-side? Cartridge. Two separate handles you screw? Compression. Wide, clean base with a minimalist look? Ceramic disc.
The Tools You’ll Actually Need
Short list. Nothing fancy.
An adjustable wrench, a Phillips-head and flathead screwdriver, needle-nose pliers, and replacement parts — which I’ll get to in a moment. Throw in a towel or two. And grab a cup to catch the water that’ll dribble out when you open things up, because there’s always some. Always.
Replacement parts are where people spiral into overthinking. For a compression faucet, you’re almost certainly swapping out a rubber washer — fifty cents at any hardware store. Cartridge faucets need the cartridge itself replaced. Ball faucets — Delta and Moen both sell complete repair kits ($10-15) with everything the ball assembly could possibly need. Ceramic disc faucets rarely fail, but when they do, you’re pulling out and replacing the disc cylinder.
Turn Off the Water First — Seriously
I know how obvious that sounds. But a friend of mine in Portland skipped this step back in 2019 because he was “just going to take a quick look.” He ended up with water across his bathroom ceiling. Turn. Off. The water.
Look under the sink for the shutoff valves — two knobs or oval handles on the supply lines running into the wall. Turn them clockwise until they stop. Then open the faucet to bleed off whatever pressure is still sitting in the line. When nothing comes out, you’re clear.
If the shutoff valves are dead (common in older homes), you’ll need to kill the main water supply to the whole house instead. It’s usually lurking in the basement, crawlspace, or near the water meter.
How to Fix a Compression Faucet (The Most Common Beginner Fix)
Most people start here. And honestly, it’s the most satisfying fix because the logic is brutally direct — something wore out, you replace it, done.
Step-by-Step
Pull off the handle. There’s usually a decorative cap on top — pry it with a flathead screwdriver and you’ll find a screw underneath. Remove the screw, and the handle should come straight off. Stuck? Wiggle it gently. Don’t force it.
Below the handle sits a packing nut. Unscrew it counterclockwise with your adjustable wrench. Inside is the stem — pull it out. At the bottom of that stem, a rubber washer is held in place by a small brass screw. That washer is almost certainly your culprit. It’ll look flattened, cracked, or just generally chewed up.
Take the old washer to the hardware store and match it. Swap it out, put everything back in reverse order, restore the water, and test. That’s genuinely the whole repair ninety percent of the time. Four dollars. Done.
How to Fix a Cartridge Faucet
Moen is probably the cartridge brand you’ll encounter most often in North American homes, and their cartridges are easy to track down. The process is pretty consistent across brands, though.
Remove the handle the same way — cap, screw, pull. The cartridge sits in the valve body, usually pinned in place by a retaining clip or nut. Pull the clip with needle-nose pliers, then grab the top of the cartridge and tug it straight up. Moderate effort should do it — some people use the handle itself as a makeshift grip.
Bring the old cartridge to the hardware store or look up the model number online. Replacements run $10-30 depending on brand. Moen cartridge replacement guide Slide the new one in — the ears on the cartridge need to line up with the slots in the valve body, so pay attention to that. Reassemble, turn the water on, test.
How to Fix a Ball Faucet
These are the trickiest to tackle yourself. Not because they’re technically complex, but because there are more small pieces involved. A ball faucet uses a rotating ball mechanism to control both temperature and flow, and several things can wear out at once.
Buy a complete repair kit matched to your faucet model — this removes all the guesswork. The kit comes with springs, seats, O-rings, and usually a new ball. Remove the handle, then the cap and collar underneath (you’ll need both wrench and pliers), then fish out the ball assembly and all the tiny springs and seats from inside the cavity. Replace everything from the kit and reassemble. The first time you take one apart it looks like a small explosion happened — but lay the pieces out in sequence and putting it back is genuinely straightforward.
Bottom Line
Here’s what most of these guides get wrong: they treat a leaky faucet like a mechanical problem when it’s really a confidence problem. The actual repair is almost never the hard part. The hard part is talking yourself into believing you won’t flood the kitchen.
But faucets are designed to be taken apart. The parts are meant to be swapped out. Nobody’s going to void a warranty or destroy a pipe if you follow these steps carefully. The plumbing industry, frankly, doesn’t advertise this too loudly. A plumber might bill you $150-300 for a job that costs $12 in parts and 45 minutes. That gap exists not because the repair is hard — it’s because most people never realize it isn’t.
Fix one faucet yourself and you’ll never call a plumber for a drip again.
Frequently Asked Questions
How do I know what’s causing my faucet to leak?
Location tells you a lot. A drip from the spout points to internal wear — the washer, cartridge, or ball assembly. Leaking around the base of the handle usually means the O-rings are shot. A slow drip when the faucet is completely off? Almost always a washer or seat problem you can knock out in under an hour.
Can I fix a leaky faucet without any plumbing experience?
Yes — and I’d argue compression and cartridge faucets are among the most forgiving DIY repairs in the house. No prior experience needed, just the right parts and a willingness to move slowly. Watch one YouTube video of your specific faucet type before you start. You’ll feel dramatically more comfortable.
What if I reassemble the faucet and it still drips?
Don’t spiral. It usually means the replacement part is slightly off in size, or something didn’t seat quite right. Shut the water off again, take it apart, and check that all washers and O-rings are sitting properly and are actually the right fit. Sometimes the seat itself — the metal surface the washer presses against — has worn down and needs how to resurface a faucet seat a quick resurfacing with a seat wrench tool.
How long does this repair actually take?
Compression faucet? Realistically 20-40 minutes the first time, including a hardware store run if you’re starting from scratch. Cartridge faucets are roughly the same. Ball faucets can stretch to 45-60 minutes because of all the small components — but do it once and you’ll cut that time in half next time around.
