Common Causes of a Bathroom Sink Faucet That Won't Turn Off

When a bathroom sink faucet refuses to turn off, it can be a frustrating experience that often leads to increased water bills and potential damage to your plumbing system. Understanding the common causes of this issue is crucial for effective troubleshooting and resolution. Below, we will explore some of the key reasons why your faucet may not be functioning properly.

1. Worn-Out Washer

One of the most common culprits behind a faucet that won't turn off is a worn-out washer.
