Do your faucets make unusual noises when you turn on the tap? Bangs and grumbling sounds that come from the faucet can be due to pipe issues or faulty faucet hardware. Here is how you can determine the source for unwanted faucet sounds:

Pipes

If you have a new home your pipes may be too narrow, causing unusual banging or screeching sounds to come from your faucet. However, if your home is older, similar sounds from your faucet could be due to mineral build up in your pipes that affect water distribution. In both situations, it’s a good idea to call a professional to determine why your faucet is making noise and determine if your pipes need replacing. 

Faucet

Sounds coming from your faucet can also be due to a loose component in the faucet itself, such as a loose washer or misaligned hardware. Try to resolve the problem by tightening or replacing your washer and see if the unwanted sound persists. If your faucet continues to make sounds, examine the washer seat as clogs can cause humming or whistling sounds. 

If you find that the unwanted noise continues, it's best to call a professional who can quickly identify and fix the issue.
