In this tutorial, we learn how to replace a faucet washer. To start, you will first need to prepare this by turning off the water to your faucet completely. Then, you will turn on the faucet to make sure no more water is coming out. After this, remove the headgear from the faucet. You can do this with a screwdriver and a wrench. After everything is removed, replace the faucet washer with a new one. From here, you will place the parts back on in the same way you removed them. When finished, turn your water back on and then test it out to make sure it works!
