What to Do About a Noisy Faucet

water in faucet

If using a bathroom or kitchen faucet is a wake-up call for others in the house, your faucets are too noisy. Water flowing through a pipe and out of a faucet ought to make a soothing, zen-like sound. However, a variety of other audio effects may be emitted such as screeching, spitting sounds, or loud banging. If it’s gotten to the point of an ongoing annoyance that disturbs family members and frightens small pets, it’s time to trace the sound to its source.

  • A screeching or high-pitched squealing sound is typically caused by the rubber washers inside a faucet becoming hard and inflexible due to age. The washer is no longer pliable and forms a rigid restriction to the flow of water that creates that annoying sound. This washer is the very same one you would replace if  you had a common dripping faucet. So if you’re up for that sort of simple DIY fix, go ahead and give it a try. If not, any qualified plumber can handle it for you.
  • Spitting or coughing noises are very often caused by an inconsistent stream right where the water comes out of the faucet. The aerator screen installed in the mouth of the faucet may become clogged with mineral deposits that disrupt the smooth flow of water and create spurts and squirts which result in that spitting sound. Typically the aerator simply screws into the mouth of the faucet and can be easily removed. At that point, you can soak it in vinegar to try to dissolve the mineral deposits. If the aerator is severely encrusted, however, it’s probably a better idea to pick up a new one at any hardware store or home center and replace it.
  • Knocking or rattling sounds (particularly when the faucet is shut off) are called, appropriately, “water hammer.” It’s actually a shock wave passing through your water supply line when free flow of water through the pipe is suddenly turned off. This rattles the water pipe causing a knocking or hammering sound. A qualified plumber can install in-line water hammer arrestors that act as shock absorbers and take the knock out of your pipes. A contributing factor to water hammer is high water pressure coming from the municipal water line. The plumber can also check the household pressure and adjust the regulator if necessary.
