It’s a good thing that your plumbing is reliable. When your plumbing is making sounds or is loud, you might start to worry. While some sounds are normal, others aren’t. We’ll walk you through five common sounds and how to resolve them.

These noises include:

  • Plumbing is whistling
  • Plumbing is gurgling
  • Plumbing is humming
  • Plumbing is vibrating
  • Plumbing is bubbling

1. Plumbing is Whistling

If your plumbing is whistling, you could be dealing with several issues.

Cause: Mineral Buildup

More than 90% of U.S. homes have hard water, which means it has too much calcium and magnesium. These minerals can accumulate in your pipes and appliances, causing clogs and less efficient operation.

If you struggle with soap scum, clogged pipes or appliances wearing out quickly, you might have hard water. Having a plumber install a water softener is the best way to solve this problem.

Cause: Old Pipes

Plumbing doesn’t work forever. If you have an older home, you should know what pipe material you have and how long it lasts.

  • Brass: up to 100 years
  • Copper: up to 80 years
  • PVC: up to 45 years

If your pipes are near the end of their lifetime and you’re dealing with leaks, discolored water or low water pressure, it may be time to have new ones installed.

Cause: High Water Pressure

This can be caused by your water supplier or issues with your water heater. A telltale indication of high water pressure is hearing knocking in your pipes, particularly after turning off a faucet.

If this is what’s causing the problem, a plumber can check and replace your home’s pressure-reducing valve as necessary.

2. Plumbing is Gurgling

Gurgling isn’t a good noise. It’s usually a symptom that you’re experiencing some sort of blockage or clog. Here are three of the most common kinds.

Cause: Plugged Drain

Your drain can either be partially or fully clogged. Here’s the difference:

  • Partial clog—water drains more slowly than normal.
  • Full clog—water goes up instead of draining, particularly in multiple drains.

It can be enticing to use a liquid drain opener to fix the issue, but this can create more problems. These products are corrosive and can eat away at your pipes. It’s always best to have a plumber unblock your pipes, either via a snake or jetting.

Cause: Blocked Sewer Line

Your home has a sewer pipe that carries waste to the main sewer line, usually situated in your yard or in the street. If this pipe gets plugged, you will likely be dealing with backup in your basement.

Things that can block or clog this pipe includes tree roots searching for water or by flushing bathroom products other than toilet paper. Whether you’re coping with tree roots or a clogged toilet, you’re going to need help from a professional plumber.

Cause: Plugged Sewer Vent or P-Trap

The sewer vent system and P-traps on your drains keep icky plumbing smells out of your home. If they get blocked, you’ll likely notice gurgling, experience slow draining or smell sewage. A plumber can help you get to the root of and resolve this smelly problem.

3. Plumbing is Humming

If your plumbing is humming, you’re not just dealing with an annoying sound.

Cause: High Water Pressure

Humming means your home’s water pressure is probably too high. This can create problems such as water leaks and damage to faucets and other fixtures. A plumber can help you regulate water pressure, which should be around 60–70 PSI.

4. Plumbing is Vibrating

If your plumbing is vibrating, three problems could be creating this noise.

Cause: Unsecured Pipe Clamp

The most common trigger of vibrating plumbing is a loose pipe clamp. This hardware keeps pipes in place when water is flowing through them. If the loose pipe is below a sink, you might be able to correct this issue yourself. If it’s behind a wall, it’s recommended to call a plumber.

Cause: High Water Pressure or Water Hammer

Less commonly, pipes can vibrate because of high water pressure or a water hammer, which happens when water that’s moving fast runs into a closed valve. A plumber can identify and fix these issues.

5. Plumbing is Bubbling

If your plumbing is bubbling, you’re probably dealing with problems related to gurgling plumbing.

Cause: Blocked or Incorrectly Vented Drain

Whether you’re dealing with a blocked or improperly vented drain, a plumber can fix it.
