Compression faucets are typically older faucets with separate hot and cold handles. The handles turn up to 360 degrees and rise just a bit when turned to the on position.
Repairing a compression faucet is a project many homeowners who are handy with a few basic tools can do themselves. If you’re not sure what type of faucet you have, see if you can identify the brand and model. Take this information with you to your local store to get the appropriate replacement parts.
Compression faucets typically leak because of worn washers or damaged valve
seats. You can fix these problems yourself by replacing the O-rings. Because
O-rings come in several sizes, plan to take the O-ring you’re replacing to the
store to match it. To avoid a trip to the store in the middle of your project,
you may find it more convenient to pick up a variety pack of O-rings and
washers commonly used in faucet repairs before beginning your project. While
you’re at the store, you can make your job even easier by picking up a repair
kit for your faucet. These kits have everything you need to replace all the
parts in your faucet at one time, so your repair will last even longer.
Special tools like a handle puller may also come in handy.
