Loud outdoor faucets can be easy to fix with the right tools. If you notice a loud vibrating noise when you turn on the faucet, that can be a sign that the faucet washer is worn out. Luckily, this is a low-cost fix that take fewer than 10 minutes.
Start by making sure you have the right tools to complete the job.
You will need:
Start by turning off the water to the faucet. Use a wrench to remove the retaining nut attached to the sill cock or spigot. The entire faucet does not need to be removed from the wall, only the nut that retains the sill cock.
Remove the handle and stem from the sill cock. At the end of the stem there is a screw, remove the screw and remove the washer. Replace the old washer with a newly purchased one. If you notice that the washer is in good condition, make sure the screw at the end of the stem is not loose. Use Threadlocker or a similar material on the screw and then tighten it. This will make sure that the screw is tightly in place. If the faucet has a spring-loaded sleeve near the washer, the entire faucet will need to be replaced.
Reassemble the washer, screw and replace the stem back into the faucet. Turn the water on to the faucet. Enjoy a noise-less faucet.
