Why Does My Faucet Make Noise When I Turn It On?

Squeaks, whistles, and clunks from your faucet can indicate underlying issues. We explain what those noises mean.

Decoding Faucet Noises

A healthy faucet should operate quietly. When it starts making strange noises, it's trying to tell you something is wrong.

Common Sounds and Their Causes

• Whistling or Squealing: Usually caused by a worn-out washer or a loose part inside the faucet assembly restricting water flow.
• Clunking or Banging: Often a sign of "water hammer," caused by high water pressure or poorly secured pipes banging against the wall framing.
• Chattering: A rapid clicking or chattering sound can indicate a faulty valve or loose internal components.

Silencing the Noise

Many faucet noises can be fixed by disassembling the unit and replacing worn washers, O-rings, or cartridges. For water hammer issues, a plumber may need to install water hammer arrestors.
