Is It Normal to Hear Water Running Through Pipes? Understanding Common Plumbing Noises
Homes, especially older ones, can produce a variety of sounds—from creaking wood to rattling walls—but when it comes to plumbing noises, it’s important not to overlook them. Plumbing-related sounds like gurgling, banging, or whistling often indicate issues with water pressure, trapped air, or faulty components. Recognizing what each plumbing noise means can help you take timely action and avoid serious problems.
What's Normal When You Hear Water Running Through Pipes?
Some plumbing noises are completely normal and are simply the sound of your home's water system in action. It's common to hear a light whoosh of water flowing through the pipes when you turn on a faucet, shower, or run an appliance. Occasionally, pipes may bang or clatter as water moves through them, particularly when valves open or close quickly. This noise—commonly known as water hammer—can be harmless in mild cases but may also suggest high water pressure or loose fittings that need attention.
What's Not Normal - Plumbing Noises in Pipes You Shouldn't Ignore
Unusual and persistent plumbing noises are often signs that something is wrong with your system. If you hear any of the following sounds, it’s a good idea to call a plumber for further inspection:
- Whistling
- Vibrations
- Banging
- Rumbling
Resolving Plumbing Noises and Water Running Issues the Right Way
Understanding what causes these sounds can help you or your plumber quickly pinpoint and resolve the issue:
- Whistling: Commonly occurs near toilets and usually points to a leaking or worn-out toilet valve. You can often hear the whistling inside the tank. A plumber may adjust the internal mechanism or replace the valve entirely if the leak is significant.
- Vibrating: Often the result of a deteriorated fill valve in the toilet. An old fill valve may fail to form a tight seal, causing internal parts to vibrate. Replacing the fill valve typically eliminates the noise.
- Banging: This is frequently caused by unsecured pipes that hit nearby walls or framing when water flows through them. The expansion and contraction of pipes with temperature changes exacerbate this issue. It may also indicate water hammer due to excessive pressure. Solutions range from securing the pipes to installing a water hammer arrestor or adjusting water pressure.
- Rumbling: Usually originates from the water heater and suggests sediment buildup inside the tank. As water heats, the trapped sediment creates turbulence and rumbling. Regular maintenance, such as flushing the tank, can resolve this issue.
