Why is My Plumbing Making Noise?


Our Atascadero plumbers are here with a list of culprits and what you can do about it.

Tis the season for things that go bump in the night. But while it might be spooky season, you don’t want that to apply to your home’s pipes. Bumps, knocks, rattles, and other nefarious noises within the walls, floors, and basement of your house might just be your plumbing. And that could be a lot scarier than a Halloween fright.

If that’s the case, it’s not only scary, but it could be a sign of a plumbing problem – one that won’t just keep you up and night nervously peering over the end of your blankets. So, why is my plumbing making noise?

Bumping, Banging, and Rattling

Banging noises coming from your pipes are likely indicative of a water flow or pressure issue – either trapped air bubbles or water hammers. Yes, water hammers.

A water hammer, also known as hydraulic shock, occurs when fluid in motion is suddenly stopped when a faucet or valve is shut off. This sudden stopping creates a pressure wave that travels through the pipes, causing a bang. It’s not necessarily a loud bang, either; it can also be a series of lighter knocks.

Also, trapped air in a water line can also cause banging as a faucet is turned on. You might also hear a bubbling noise as air moves up and out of the line. There are a variety of reasons for these problems, and you’ll probably need a professional plumber to address the problem.

If you’re hearing lighter knocking or rattling, it could be a sign that it’s something as simple as a loose bracket or fastener securing a pipe.

Humming Noises

You might think your pipes are singing to you. But when it sounds like they’re humming, it’s actually vibration from high water pressure. This can occur in any home. But your home is particularly susceptible if you draw your water from a well. Check that your water tank is set no higher than 55 PSI.

If you don’t have access to a water pressure meter or are uncertain about the right setting, contact the pros.

Gurgling Sounds

If you’re hearing a gurgling noise when water is draining, this is a clear-cut sign of a clog somewhere in the plumbing system. It could be a physical obstruction like a piece of debris or food or the build-up of soap and dirt.

Whistling or Squealing

A whistling or squealing noise coming from your pipes can certainly be unsettling, but it’s likely something as simple as broken or worn-out washers near your dishwasher or washing machine. Those appliances cause a significant amount of movement, causing washers to loosen and wear out, along with nuts and bolts.

If your washer or dishwasher is whistling while it works, check the fittings or have a plumber give it a proper inspection.

If you need your knocks, bangs, or whistling in your pipes checked out, our Atascadero plumbers are always a call or click away.
