Identify Your Faucet Type
The repair depends on the design. There are four main types.
- Compression faucets: two handles, with rubber washers inside
- Ball faucets: a single handle with a rotating ball
- Cartridge faucets: one or two handles with a replaceable cartridge
- Ceramic disc faucets: a single handle with ceramic discs
Tools and Parts You Need
- Adjustable wrench and screwdrivers
- Allen wrench set
- Replacement washers, O-rings, cartridge or seals
- Plumber’s grease
- White vinegar and a small brush
- A towel and a bowl for small parts
How to Fix a Leaky Faucet Step by Step
1. Turn Off the Water
Close the shut-off valves under the sink. Then open the faucet to drain any remaining water. Plug the drain so small parts cannot fall in.
2. Remove the Handle
Pry off the decorative cap with a small screwdriver. Next, remove the screw underneath. Lift off the handle. Take photos as you go so you can reassemble everything correctly.
3. Take Out the Inner Parts
Use a wrench to unscrew the packing nut or retaining cap. Then pull out the stem, cartridge or ball assembly. Inspect each piece for wear.
4. Replace Worn Parts
Check rubber washers, O-rings and seals for cracks or flattening. Replace any damaged part with an exact match. Take the old part to the hardware store for comparison. If you have a cartridge faucet, replace the whole cartridge.
5. Clean Mineral Buildup
Soak metal parts and the valve seat in vinegar for 30 minutes. Then scrub off deposits. For help with stubborn deposits, see how to remove hard water stains.
6. Reassemble the Faucet
Apply a thin layer of plumber’s grease to rubber parts. Put everything back in reverse order. Tighten fittings gently without forcing them.
7. Test for Leaks
Turn the water back on slowly. Run the faucet and check for drips at the spout and base. If it still leaks, recheck the seals.
Common Causes of Faucet Leaks
- Worn washers or O-rings
- Corroded valve seats
- Loose parts
- Damaged cartridges
- High water pressure
When to Replace the Faucet
Consider a new faucet if it is more than 15 years old, heavily corroded or repeatedly leaks after repairs. Also call a plumber if you cannot stop the leak or find water under the sink. A running toilet may add to your bill too, so read how to fix a running toilet.
