A constantly dripping faucet isn’t just annoying—it also wastes water and raises your utility bills. Yet calling a plumber for a leaky faucet could mean paying a premium, especially if it’s an after-hours emergency. Fortunately, you can often fix the problem on your own by following six straightforward steps. Here’s a quick guide on how to replace a worn-out washer or cartridge, stop the leak, and keep your faucet running smoothly.
1) Gather the Necessary Tools
Before you begin, you’ll need a few essentials:
- Screwdriver (flat-head or Phillips, depending on the faucet handle)
- Adjustable wrench or channel-lock pliers
- Needle-nose pliers (to reach into tight spaces)
- Pick tool or small hook (for pulling out springs and washers)
- Replacement washers, springs, or cartridge (verify your faucet brand and model)
Also, set a folded towel or rag on the counter to protect surfaces and keep small parts from rolling away.
2) Turn Off the Water
Locate the shut-off valves (angle stops) under the sink—one for hot water, one for cold. Turn them clockwise to shut off flow. If you’re unsure which side is leaking, turn off one and watch the drip. If it continues, turn that valve back on and turn off the other. Once the water is off, open the faucet to confirm no water is flowing.
3) Remove the Handle
Look for a small screw on the handle (it might be under a decorative cap). Use your screwdriver to loosen it, then carefully lift the handle away. Set the handle aside on your towel to avoid scratches or damage.
4) Replace Washer and Packing Nut
- Check the Packing Nut: Once the handle is off, you’ll see a packing nut or retaining nut. Use an adjustable wrench to see if it’s loose. A slight tightening might solve the leak.
- Remove the Cartridge: If tightening doesn’t help, unscrew the packing nut completely and pull out the faucet cartridge. Pay attention to its orientation.
- Take Out Springs and Washers: Some faucet designs have a spring under a small rubber washer at the bottom of the cartridge seat. Use needle-nose pliers or a pick tool to extract them.
- Install New Parts: Place the new spring in the washer (if your faucet uses them), then slide or press them into the seat. If you have a complete cartridge replacement, ensure you’re using the correct model for your faucet.
5) Reassemble and Assess
- Reinsert the Cartridge: Align it the same way it came out. Make sure any tabs or notches match the faucet body.
- Tighten the Packing Nut: Go gently with the wrench; over-tightening can strip threads or damage parts.
- Reattach the Handle: Secure it with the screw.
- Restore Water Flow: Turn the shut-off valve back on. Check for drips and leaks around the handle and spout. If the leak persists, double-check that you installed the correct parts and everything is seated properly.
6) Confirm No More Drips
Turn the faucet on and off several times, then leave it off to see if any droplets appear. Examine the handle area and underneath the sink to ensure there are no hidden leaks. If the faucet is dry and silent, you’ve successfully fixed your leak. If it continues to drip even after replacing washers and cartridges, the faucet body might be damaged, or you might need specialized parts.
Remember: not all faucets are designed the same. Some use ceramic discs, while others rely on ball or cartridge mechanisms. Check your faucet’s brand and model so you can purchase the correct replacement parts.
