Water pipes making noise humming can be a stressful and unsettling experience, especially if you're not sure what's causing it.

Air leaks are a common reason for humming pipes, as they can create a hissing or whistling sound.

Loose connections can also cause humming pipes, as they can lead to vibrations that produce the noise.

If you notice your water pipes humming, it's essential to identify the cause to prevent further damage and potential water waste.

Causes of Noisy Water Pipes

Noisy water pipes can be caused by pressure issues, which can lead to loud banging sounds. This is often due to the water hammer effect, where high pressure in the pipes makes the water inside bang against the shut-off valve or pipe walls.

Air in pipes is another common cause of pipe noises, including gurgling sounds and whistling noises. You may also hear your pipes humming or squeaking.

Loose components can also cause noisy pipes, such as loose piping that can sway and hit against walls or objects, causing loud banging sounds. This can lead to damage to your pipes in the long run, resulting in leaks.

Clogs or obstructions in the pipes can also cause gurgling sounds and other noises. Depending on your home setup, you may be able to locate the source of the problem by listening and looking for loose pipes or other issues.

Identifying Noisy Pipe Issues

Pipes that make humming noises can be a sign of a plumbing problem that needs to be addressed by a professional plumber. Pipes making noise often indicate a home has a problem with either water flow or water pressure.

Excessive water pressure can cause thrumming or vibrating pipes. You can test your water pressure at home by purchasing a threaded pressure gauge that screws directly onto a faucet or valve. Make sure your home's water pressure does not exceed 80 psi.

Loose components and clogs or obstructions in the pipes can also cause humming noises. In some cases, the issue might be as simple as a worn washer or a grimy aerator inside the faucet itself.

Is Normal Noise?

Occasional pipe noises might not be a cause for concern, but persistent or loud noises are often a sign of a plumbing issue.

Ignoring pipe noises can lead to more serious problems developing over time, so it's essential to address the issue.

If you're wondering whether it's normal for your pipes to make noise, consider this: pipes that make occasional noise may not be a problem, but anything too disruptive or continuing might be a sign that you've got a plumbing problem.

In most cases, strange noises from your pipes won't be a ghost, but instead a plumbing problem that will only get worse over time.

Don't assume that pipe noises will work themselves out; instead, address the issue promptly to avoid more serious problems.

Whistling Noises

Whistling noises from your pipes can be unsettling, but they're often a sign of a relatively simple issue. You might hear your pipes whistling when you turn on the faucet, and it's usually caused by a worn washer, loose brass screw, or grimy aerator inside the faucet itself.

Replacing the worn parts should fix the problem. If the whistling sound seems to come from everywhere, you may have too much mineral buildup, a worn main water supply valve, or an ineffective pressure regulator.

A whistling toilet that quiets down after the tank is filled usually needs a new ballcock valve. To fix this issue, simply bend the float arm down a little so the ballcock turns off sooner.

A toilet that whistles all the time probably has an issue with the vertical overflow tube. High-pitched whistling from the plumbing is caused by excessive water pressure or flow speed.

If your water pressure exceeds 60 psi, it's likely the pipes will give a high-pitched noise. Lowering the water pressure to an appropriate level can fix the issue.

Hammering

Hammering is a common noisy pipe problem that can be caused by high pressure in the pipes. This occurs when the water is turned off and the water inside bangs against the shut-off valve or pipe walls.

The noise is usually a distinct hammering sound and only occurs after a faucet or appliance is turned off. This is because the flow of water is cut off abruptly, causing the water to slam against the shut-off valve.

To stop a water hammer, you can try resetting the water system's air chambers. This can be done in about 10 minutes.

Water hammer can also be caused by the sudden stop of water flow, which can be prevented by installing a PRV to reduce high pressure. This device can help mitigate the force of the water and stop the pipes from making noise.

Commercial air cushions, also known as water hammer arrestors, can be attached to the pipe to provide a cushioning effect. These devices can help prevent water hammering by absorbing the force of the water.

The air in the vertical riser behind each tap can be lost over time, causing water hammering to develop. This can be fixed by shutting off the main water valve, turning on all taps, and draining the entire house.

Preventing and Repairing Noisy Issues

Loose components are a common cause of noisy pipes. Excessive wear can result in worn washers and loose pipes, which can be tightened to stop the noise.

Water supply lines should be checked if the water hammer sound doesn't go away after resetting the pressure chambers. Some older homes' pipes aren't secured well, so they move too much and create waves that lead to water hammers.

Apply clips and plumber's tape wherever necessary to secure the supply pipes. This can help prevent noisy pipes and fix existing issues.

Replacing faulty parts can also solve the problem. If the noise is coming from parts that are in need of replacement, such as washers, O-rings, or other components, you can replace these parts in a faucet or valve.

Typically, water piping is anchored every 8 to 10 feet vertically and 6 to 8 feet horizontally. If the pipes are not anchored properly, the water pressure when water is turned on will cause them to rattle and shake, creating a banging sound as they bang against the pipe anchors and other pipes.

Here are some common causes of noisy pipes and their solutions:

  • Loose components: Tighten loose washers and pipes
  • Water supply lines: Secure supply pipes with clips and plumber's tape
  • Replacing faulty parts: Replace worn-out or damaged parts
  • Loss or faulty anchoring: Anchor pipes every 8-10 feet vertically and 6-8 feet horizontally
