Replacing a faucet washer is a simple repair that can fix common issues like dripping faucets. Here’s a step-by-step guide to replacing a faucet washer:
Tools and Materials Needed:
Adjustable wrench
Flathead screwdriver
Replacement faucet washer (make sure it’s the right size)
Plumber's grease (optional)
Towel or rag
Steps to Replace a Faucet Washer:
1. Turn Off the Water Supply
Locate the shut-off valves under the sink (usually below the faucet). Turn them clockwise to shut off the water supply to the faucet. If there are no individual shut-off valves, turn off the main water supply for your home.
Open the faucet to release any remaining water in the pipes.
2. Plug the Drain
Use a sink plug or a rag to block the drain. This will prevent any small parts from falling into the drain while you work.
3. Remove the Faucet Handle
Use a screwdriver to remove the screw that holds the faucet handle in place. The screw is typically located under a decorative cap or behind the handle.
Once the screw is removed, gently pull off the faucet handle. If it’s stuck, use a flathead screwdriver to gently pry it loose.
4. Disassemble the Faucet
Use an adjustable wrench to remove the nut or bolt that holds the faucet stem (or valve) in place. Depending on the type of faucet, you may need to unscrew a few additional parts to fully remove the stem or cartridge.
Carefully pull out the faucet stem or valve.
5. Locate the Washer
Once the stem or valve is removed, locate the washer at the bottom of the stem or valve. It’s typically a small, round rubber or metal disc that seals the flow of water when the faucet is turned off.
Inspect the washer for wear or damage. If it’s cracked, brittle, or flattened, it’s time to replace it.
6. Remove the Old Washer
Use a flathead screwdriver to gently pry out the old washer from the valve stem. Be cautious not to damage the valve seat during this process.
7. Install the New Washer
Place the new washer onto the valve stem, ensuring it fits snugly in the designated groove.
You may want to apply a small amount of plumber's grease to the washer to help it seal properly and reduce friction.
8. Reassemble the Faucet
Carefully reinsert the stem or valve back into the faucet body.
Tighten the nut or bolt that holds the stem or valve in place using an adjustable wrench.
9. Reattach the Faucet Handle
Slide the handle back onto the faucet stem and secure it with the screw you removed earlier.
Tighten the screw with a screwdriver.
10. Turn the Water Supply Back On
Open the shut-off valves under the sink (or the main water supply) to restore water flow to the faucet.
Test the faucet by turning it on and off to ensure the leak is fixed. If the faucet still leaks, double-check that the washer is correctly installed and that all components are tightly secured.
Additional Tips:
Use the Right Size Washer: Make sure to purchase the correct size replacement washer for your faucet. If you're unsure, bring the old washer to the store to match it.
Clean the Valve Seat: Before installing the new washer, clean the valve seat (where the washer rests) with a cloth or mild abrasive to remove any debris or buildup that could prevent a good seal.
Check for Other Issues: If replacing the washer doesn’t solve the problem, the faucet’s valve or stem may be damaged, and further repairs or replacement may be necessary.
