Diagnosis
A persistent drip from your bathroom faucet is usually caused by a worn-out washer or O-ring within the handle mechanism. These small rubber components are responsible for creating a watertight seal. If you don't address this issue, the constant dripping can lead to significant water waste, a higher utility bill, and potentially unsightly stains in your sink or bathtub.
Tools Needed
- Adjustable wrench
- Phillips head screwdriver
- Flathead screwdriver
- Plumber's grease
- Replacement washers and O-rings (faucet repair kit)
Warnings
- Always turn off the main water supply to the faucet before starting any repairs to prevent flooding.
- Be gentle when removing parts; old faucet components can be brittle and may break if too much force is applied.
- Ensure you have the correct replacement parts for your specific faucet model before disassembling.
Step-by-Step Instructions
- Locate and shut off the water supply valves, typically found beneath the sink.
- Turn the faucet on to allow any residual water to drain out.
- Gently lift off the decorative cap on the faucet handle using a flat-head screwdriver.
- Remove the handle by unscrewing the Phillips head screw and pulling the handle off.
- Using an adjustable wrench, loosen and remove the packing nut or bonnet nut.
- Carefully extract the stem or cartridge assembly.
- Pinpoint and remove the old, deteriorated washer and O-ring from the stem.
- Install new washer and O-ring components, typically found in a faucet repair kit. Apply a small amount of plumber's grease to the new O-ring for a better seal.
- Reassemble the faucet by inserting the stem, tightening the packing nut, reattaching the handle, and securing it with its screw.
- Slowly restore the water supply by turning the valves back on.
- Operate the faucet to confirm that the dripping has ceased.
Troubleshooting
- If the leak persists, check if the valve seat inside the faucet body is damaged. It might need to be resurfaced or replaced.
- Ensure all parts are tightened correctly. A loose packing nut or bonnet nut can still allow water to seep out.
- If the problem is with a cartridge-style faucet and replacing the O-rings/washers didn't work, the entire cartridge may need replacement.
Preventive Tips
- Avoid using abrasive cleaners or scouring pads on the faucet finish, as they can damage the protective coating.
- If you have hard water, consider installing a water softener to reduce mineral buildup that can wear down faucet parts.
- Periodically check your faucet for early signs of dripping and address them promptly to prevent further damage.
