Outdoor faucets, also called hose bibs, give you the freedom to connect a hose and use water anywhere around your home. This type of faucet is controlled by a valve stem. A rubber washer at the end of the stem controls water flowing through the faucet. This washer can deteriorate over time, necessitating its replacement.
