It’s a positive thing that your plumbing is reliable. When your plumbing is making noises or is loud, you might begin to worry. While some sounds are typical, 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 facing several issues.
Cause: Hard Water
More than 90% of U.S. homes have hard water, which means it contains too much calcium and magnesium. These minerals can build up in your pipes and appliances, causing clogs and less efficient operation.
If you have issues with soap scum, clogged pipes or appliances wearing out quickly, you might be dealing with hard water. Having a plumber install a water softener is the best way to solve this issue.
Cause: Aging Pipes
Plumbing doesn’t last forever. If you have an older home, it’s important to 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 close to the end of their lifetime and you’re dealing with leaks, rusty water or insufficient water pressure, it may be time to have them replaced.
Cause: Water Pressure Is Too High
This can be caused by your water supplier or issues with your water heater. A telltale sign of high water pressure is hearing knocking in your pipes, especially after shutting off a faucet.
If this is what’s creating the problem, a plumber can check and replace your home’s pressure-reducing valve as needed.
2. Plumbing is Gurgling
Gurgling isn’t a good sound. It’s usually a symptom that you’re experiencing some sort of blockage or clog. Here are three of the most common types.
Cause: Clogged Drain
Your drain can either be partially or fully clogged. Here’s the difference:
- Partial clog—water drains more slowly than usual.
- Full clog—water goes up instead of draining, particularly in multiple drains.
It can be enticing to use a liquid drain opener to correct the issue, but this can create more problems. These products are corrosive and can erode your pipes. It’s always recommended to have a plumber unblock your pipes, either via a snake or jetting.
Cause: Clogged Sewer Line
Your home has a sewer pipe that carries waste to the primary sewer line, usually located in your yard or in the street. If this pipe gets clogged, you will likely be dealing with backup in your basement.
Things that can obstruct or clog this pipe includes tree roots seeking water or by flushing bathroom products besides toilet paper. Whether you’re coping with tree roots or a plugged toilet, you’re going to need help from a professional plumber.
Cause: Blocked 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 hear gurgling, experience slow draining or smell sewage. A plumber can help you get to the root of and solve this smelly problem.
3. Plumbing is Humming
If your plumbing is humming, you’re not just dealing with an irritating noise.
Cause: High Water Pressure
Humming means your home’s water pressure is probably too high. This can create problems like water leaks and damage to faucets and other fixtures. A plumber can help you control water pressure, which should be around 60–70 PSI.
4. Plumbing is Vibrating
If your plumbing is vibrating, three problems could be causing this noise.
Cause: Loose Pipe Clamp
The most common cause of vibrating plumbing is an unsecured pipe clamp. This hardware keeps pipes secure when water is running through them. If the loose pipe is under a sink, you might be able to fix this issue yourself. If it’s behind a wall, it’s best to work with a plumber.
Cause: High Water Pressure or Water Hammer
Less commonly, pipes can vibrate because of high water pressure or a water hammer, which occurs when water that’s moving fast hits a closed valve. A plumber can diagnose and correct these issues.
5. Plumbing is Bubbling
If your plumbing is bubbling, you’re likely dealing with issues related to gurgling plumbing.
Cause: Clogged or Improperly Vented Drain
Whether you’re dealing with a clogged or incorrectly vented drain, a plumber can take care of it.
