Quick answerTurn off the water supply, plug the drain, remove the handle, and replace the worn washer or cartridge. Reassemble, turn water back on, test.

What you'll need

  • Adjustable wrench
  • Screwdriver set
  • Replacement washer/cartridge (take the old one to the store to match)
  • Plumber's grease (optional, $3)
  • Towel + plug for the drain

Step-by-step

  1. Turn off the water. Valves under the sink (clockwise). No valves? Shut off the main.
  2. Plug the drain. Screws and washers love disappearing down drains.
  3. Remove the handle. Pop off the decorative cap, unscrew the handle screw.
  4. Remove the cartridge/stem. Unscrew the packing nut with your wrench, pull the cartridge out.
  5. Inspect. Worn rubber washer? Cracked O-ring? Corroded seat? Replace what's worn β€” or swap the whole cartridge ($10–20).
  6. Reassemble in reverse. Don't overtighten β€” snug is enough.
  7. Turn water back on slowly and test. Run both hot and cold.

Frequently asked questions

Why does my faucet drip after I turn it off?
Worn washer, O-ring, or cartridge β€” the seal no longer closes fully. Replacement fixes it.
How much water does a leaky faucet waste?
A drip per second wastes about 3,000 gallons per year.
Do I need to turn off the main water supply?
Usually just the under-sink valves. Use the main only if those valves don't exist or don't work.
