How to Change a Washer in a Faucet: Step-by-Step Guide

Here is what you need to have to change the washer in your faucet:

You'll typically need an adjustable wrench, a screwdriver, a replacement washer (make sure it matches the size and type of your old washer), and possibly some plumber's grease.

1. Switch Off the Water Supply: Safety first! Locate the shut-off valves under the sink and turn them clockwise to stop the water flow.
2. Remove Decorative Parts: Start by taking off any decorative cap or cover on the faucet handle. Sometimes these can be popped off with a flathead screwdriver or simply unscrewed by hand.
3. Remove the Handle: Once you've exposed the handle's fastening mechanism, whether it's a screw or a nut, use the appropriate tool (usually a screwdriver or an adjustable wrench) to loosen and remove it. Then, carefully lift off the handle.
4. Use Pliers to Remove the Stem: The stem is the part that extends down into the faucet body. You may need a pair of pliers to grip onto the stem and twist it counterclockwise to loosen it from the faucet body. Be gentle to avoid damaging the stem or the faucet.
5. Remove the Old Cartridge and Washer: With the stem removed, you'll likely find the cartridge and washer assembly inside the faucet body. Depending on the faucet type, these may lift out or require some manoeuvring to remove. Use caution not to force anything, as you don't want to break any components or cause further damage.

Note: ( Determine if you need to replace the O-rings. Worn-out o-rings can cause a faucet to leak as easily as a worn washer can. If the leak is coming from the base of the faucet, the o-rings are probably worn. Place a pair of replacement o-rings at the bottom of the faucet before inserting a new washer.)

DISCLAIMER: It is advised to take professional help for these tasks, so as to avoid any chances of leakage or damage.

Steps to Change Washer in a Faucet

1. Put in the New Washer: Once you've removed the old washer, place the new one in its position. Ensure that it fits snugly and is properly seated to prevent leaks.
2. Put the Stem Back in Place: Carefully reinsert the stem into the faucet body. Make sure it aligns correctly with any grooves or slots it needs to fit into. Use gentle pressure to thread it back in place, rotating it clockwise until it's securely tightened.
3. Insert the Cap: If there's a decorative cap or cover for the faucet handle, reattach it. This step might involve screwing it back on or snapping it into place, depending on the design of the faucet.
4. Turn on the Water: Once everything is reassembled, turn the water supply back on by turning the shut-off valves counterclockwise. Start with a slow flow to check for any leaks. If everything looks good, gradually increase the water flow to normal.

What to Avoid?

1. Over-tightening: Be cautious not to over-tighten any components, especially when reattaching the stem or decorative cap. This could damage the faucet or cause it to leak.
2. Misalignment: Ensure that all parts are properly aligned and seated during reassembly. Misalignment can lead to leaks or difficulty operating the faucet.
3. Forcing Parts: If any component doesn't seem to fit or move easily, don't force it. Forcing parts can cause damage to the faucet and make the repair more challenging.
4. Ignoring Leaks: After reassembling the faucet, carefully check for any leaks before fully turning on the water supply. Ignoring leaks could lead to water damage and further issues down the line.
