What does a continuous dripping faucet usually indicate?

A continuous dripping faucet typically indicates a bad washer. Washers are small rubber or plastic components that help seal the water flow when the faucet is turned off. Over time, washers can wear out, crack, or become distorted due to water pressure and usage. When this happens, they fail to create a proper seal, leading to water leaking out and causing a constant drip.

This situation often arises in compression faucets, which rely on washers to close off the water supply. The wear and tear on these washers is the most common reason for persistent dripping, making it a reliable indicator of the issue. Replacing the bad washer usually resolves the problem and stops the dripping.
