What causes a dripping faucet?

A dripping faucet is typically caused by a worn or damaged internal component, such as a washer or valve seat, failing to create a tight seal and allowing water to leak. Over time, the constant water flow can cause additional wear and tear on the faucet components, exacerbating the problem. Other possible causes include high water pressure or a loose or corroded connection. The worn component will need to be replaced to fix a dripping faucet, which may require disassembling the faucet and replacing the necessary parts.
