A dripping faucet is one of the most common home repairs — and one you can often handle yourself with basic tools and an hour of time. Before you call a plumber, here’s what to check.
Step 1: Turn off the water. Look under the sink for the shut-off valve — usually a small knob or lever on the pipe leading to the faucet. Turn it clockwise to stop the flow. If there’s no valve under the sink, you may need to shut off the main water supply for your home.
Step 2: Identify the leak. A drip from the spout typically means a worn washer or O-ring inside. A leak at the base of the faucet usually points to a loose or damaged seal. Knowing which one you have tells you which part to inspect.
Step 3: Disassemble the handle. Remove the handle by unscrewing it — some have a small screw hidden under a decorative cap. Then take apart the faucet body to access the internal cartridge or stem. Keep the parts in order so reassembly is straightforward.
Step 4: Inspect the rubber parts. The washers and O-rings are the most common failure points. Look for cracks, flattening, or wear. If they look tired, replace them — they’re inexpensive and available at any hardware store.
Step 5: Replace and reassemble. Match the old parts exactly — take them to the store with you rather than guessing at sizes. Reassemble in reverse order, then turn the water back on slowly and check for drips.
If the leak persists after replacing washers and O-rings, the cartridge or valve seat may be damaged. Some faucets use ceramic disc cartridges that rarely wear out but can crack — inspect for visible damage. Note your faucet’s brand and model, often printed on the side or base, to find the right replacement.
When to get help — and where. If you’re unsure about the repair, you don’t have to hire a professional. Repair cafes and community workshops host events where volunteers help with exactly this kind of fix, often for free. International Repair Day, held annually on October 17, connects people with repair events in their area where you can learn skills like this hands-on. Hundreds of events are already listed on the global map.
Why this matters beyond your sink. Repairing rather than replacing supports a broader principle: products should be fixable. States have led the Right to Repair movement, passing laws that give consumers more practical access to parts, tools, and information. These laws do not require manufacturers to design products for repairability, so some faucets remain harder to fix than others. But where laws apply, manufacturers cannot require proof of purchase to provide a part — so if your faucet is under warranty, check whether replacement parts are available without jumping through hoops.
Your action: Before calling a plumber, turn off the water supply under the sink, then inspect the faucet’s handle and base to identify whether the leak is from the spout or the base — this tells you which part needs replacing. A repair that takes an hour can save the cost of a plumber’s visit and the water lost to a drip. And if you get stuck, find a local repair event — the skills you learn there will serve you on the next repair, too.
