Where’s That Weird Plumbing Noise Coming From?

Friday, August 31st, 2018

Plumbing noises are always worth paying attention to because they’re never just noises. Often, an unusual noise coming from your home’s plumbing is your first indication that something’s wrong. You could think of plumbing noises as a kind of early warning system. When you hear a weird plumbing noise, pay attention! You could save your plumbing system–and a fair bit of money, too!

Some “early warning” plumbing noises are especially notable. If you have any of the following four plumbing noises, it always pays to check them out. Here’s how to track down your sound, what’s probably making it, and what you should do about it:

Loud “bang” after turning off the water

This sounds like a loud hammering or banging sound. It happens after you turn off water that was flowing into a sink drain. Your banging sound is actually a specific plumbing phenomenon called “water hammer.” Water hammer happens when water that’s rushing through pipes suddenly stops. The force of the water suddenly stopping creates a shockwave that reverberates through your pipes as the hammering sound. If the pipes rattle and smack against other things during the shockwave, the water hammer sounds even louder.

Water hammer generally starts happening when the devices in the pipes designed to stop it stop working. Most pipes have air chambers built into them. When the water hammer shockwave hits these air chambers, they compress and absorb the force like shock absorbers. Over time, however, the air chambers may fill up with water. When air chambers fill with water, they can’t compress the shockwave, and you end up with water hammer. Draining the water in your pipes’ air chambers should take care of the problem.

Whistling shower head

This sounds like a high-pitched whistling coming from your shower head whenever you’re taking a shower. It can happen intermittently or constantly while the shower is running. This noise could be happening for a couple reasons. Most likely, something inside the shower head is partially blocking water flow. Minerals and sediment can build up inside shower heads just like any other plumbing component. Shower head clogs are especially likely if you don’t use a water softener. Cleaning the shower head should do the trick.

If your shower head still whistles after you clean it, then there might be a problem with another shower component. Most likely the washer in the shower faucet diverter is worn out or damaged. If you only hear the whistling when you use hot water, then the diverter is probably the problem. Replacing shower diverter washers is a fast and easy job. If the washer isn’t the problem, either, then you should try replacing the shower head entirely.

“Gurgling” in drain

This “gurgling” noise usually happens after you turn off water running in a sink. It could sound like water’s struggling to move through the pipes, or like water is “bubbling” in the drain. The sound could come from the drain itself, or you could hear it further down, near the trap. When a drain gurgles, it’s usually because the pipe vent isn’t working correctly. The sound you’re hearing is air rushing past the water in your sink trap.

When water moves through a pipe it pushes air down the pipe, creating a vacuum behind it. Vents exist to add air back into the pipes after water pushes it down. If vents are blocked, air has to find another way into the pipes–usually through the drain. When air pushes through to fill the vacuum, it distresses the water in the trap. Clearing the drain vent should give air an avenue to enter the pipe and solve your gurgling problem.

“Popping” noise in basement or utility closet

This “popping” noise can sound like anything from popcorn cooking to a dull thunking noise. It can be very quiet or surprisingly loud. We’re using basements and utility closets as an example, but it comes from wherever your water heater is installed. It’s tough to notice unless you’re listening for it, but the noise probably usually happens after you use your hot water. The popping noise is the sound of water boiling up from under sediment inside the water heater’s tank.

Sediment tends to build up inside water tank tanks naturally over time–especially if your home has hard water. This sediment settles into the bottom of the water heater tank and traps some water beneath it. When the tank heats water, the water trapped beneath the sediment starts to boil. Bubbles from the boiling water struggle to escape from under the sediment. These bubbles “pop” with great force, creating the sound you’re hearing. Flushing your water heater tank should do the trick. If it doesn’t, you may need to replace the tank entirely.

By identifying and doing something about these plumbing noises early, you can avoid larger plumbing problems. Don’t wait! If you’re hearing something strange in your plumbing, look into it right away. If it’s one of these problems, you’ll probably be able to fix it fast!

The Water Hammer Fix: Can You Stop Banging Pipes?

Thursday, September 3rd, 2015

Are you looking for a water hammer fix? Is the noise starting to drive crazy? Water hammer occurs when you turn the water on and your pipes respond with an audible bang – a thundering boom that is sometimes loud enough to rattle your windows and may be followed by other disturbing noises.

Water Hammer and Your Pipes

When you first hear a water hammer, it sounds incredible – like something that shouldn’t be happening inside your home at all. But the cause is surprisingly simple: the “hammer” is made from a combination of blocked pipes and pressure waves.

When you turn on water, especially for high-demand applications like pouring a bath or turning on a shower, your water system sends in a powerful gush of water through your pipes and toward its destination. But along the way, sometimes water encounters a slow valve, a sudden turn or a loose pipe that forces a sudden change or a quick stop. But the water is moving so quickly that this sudden crash creates a powerful pressure wave as the water is suddenly compressed and released. That wave is the explosive sound that travels outward, often making pipes throughout your house rattle.

Water hammer is more common with older pipes, poorly installed pipes and pipes that carry heated water. Think about a water hammer fix that will address these problems for overall healthy plumbing.

Water Hammer Problems

The blast of water hammer does not mean that something is immediately broken – after the pressure wave, water typically continues to travel as normal. But water hammer isn’t something that you want hanging around. The shockwave can knock pipes from their brackets, cause serious valve damage, encourage leaks to develop and more.

Finding a Water Hammer Fix

There are several different solutions to water hammer issues, depending on the source of the problem. One of the easiest is air chamber maintenance – most homes use air chambers that have pockets of air in the pipes to provide some cushioning as water makes tight turns. That air can sometimes leak out over time, creating problems, but you can replace it with new air. This usually requires professional help.

If your problem is a stuck valve, this is a more immediate problem that can be fixed with a simple replacement. Sometimes there is a more far-reaching issue, such as a problem with the pitch of your pipes (the angle at which they decline over a distance), but this is relatively rare.

Water hammer can also be treated with special valves call arresters that help water slow down in better ways. If you cannot solve your water hammer problems any other way, then contact a professional and ask them about installing an arrester or similar device to help prevent future noises.

Loud Pipes Disrupting Your Life? Quiet the Noise

Friday, June 6th, 2014

Loud pipes are a nuisance, and they can put a real damper on the peaceful atmosphere of your home. Imagine a quiet Sunday afternoon, curled up on the couch reading a book, and CLASH. Someone flushes the toilet, causing a cacophony of rattling and shaking. Find out what usually causes pipes to make these loud, offensive noises and what can be done about it.

Copper Pipes

Copper pipes are famous for creating noise. As hot water moves through the colder pipes, the material expands. This can cause it to make contact with a nearby structure, such as the home’s framing or wood floor. After the water moves out of the pipe, the pipe will contract back to its normal shape and stop rubbing against the other surface. Then, the noise stops.

To prevent copper pipes from making noises, it’s possible to install insulation around them to limit the expanding and contracting. Additionally, it may help to lower the setting on your water heater so that water moving through pipes isn’t quite as hot.

Minerals in Your Water

Water is full of minerals that can get left behind in the pipes. Essentially, these minerals create a coating on the walls of the pipes and cause air bubbles to form. As warm water moves through the pipes or as the water inside the pipes becomes warm, the bubbles pop and make noise.

If mineral buildup is the culprit, flushing out the water heater should help. Flushing is part of annual service a water heater technician provides. Scheduling annual tuneups for the water heater helps it operate efficiently and removes buildup that can harm not just the pipes but the system, too.

Loose Pipes

If pipes are loosely secured to surfaces in the home, they can vibrate as water moving through them creates pressure.

If the problem is as simple as loose connections causing vibrating pipes, tightening these connections should remedy the loud pipes.

Water Hammer

Water hammer creates a clanging or banging noise, which results from a closed valve stopping the force of water flow.

Sometimes, stopping water hammer is as simple as slowly turning water on and off to offset the strong force of water causing the banging noise. However, you may need a plumber to install control valves to absorb the strong force of water when it stops.

Before you can get rid of the annoying noises, you need expert help figuring out the source of the problem. Call a licensed plumber to inspect your pipes and find out the true culprit of the noises in your home.
