But why do pipes make noise? We’ll break it down in this post. And if you still need help finding and fixing the issue, contact King’s Services for trusted plumbing services in West St. Paul, MB.
When To Worry About the Sounds in Your West St. Paul, MB, Walls
Humming, shaking, and popping are just a few of the sounds you’ll hear when your plumbing needs maintenance. The following sections break down the most common causes and what they mean.
High Water Pressure Forces Pipes To Hum and Vibrate
When the pressure in your system climbs too high, usually above 50 psi, water forces its way through the pipes too fast and causes humming or vibrating sounds, especially near valves and joints.
This usually happens when a regulator fails or when the supply line pushes water into the system without enough control. The extra force puts constant strain on joints, fittings and pipe walls. Over time the seals and valves will deteriorate and increase the chance of leaks.
Loose Pipes Shake and Slam Against Walls
Pipes come loose when brackets break, slip out of place, or never get installed in the first place. Builders sometimes miss supports in hard-to-reach spots. Over time, vibrations from normal water use wear out the fasteners that keep everything in place.
Once pipes lose support, they start to slam against framing, drywall, or other pipes nearby every time water moves through them. If you wait to fix this, the movement will weaken the joints and increase the risk of leaks. If you hear banging inside your walls, reach out to an expert at King's Services.
Whistling and Bubbling
Why do pipes make noise? Sometimes it's because air in pipes interrupts water flow and creates sharp whistles, bubbling sounds or loud bangs behind the walls. These noises often show up after plumbing work or when a pressure change pulls air into the lines.
Once air spreads through the system, it throws off pressure and causes sudden surges or uneven flow.
To flush the air out, open every tap in your home, starting with the one closest to the main water supply. Let the water run for a few minutes, then turn off each tap one at a time, working back toward the starting point.
Mineral Deposits, Narrow Pipes, and Hissing
In most parts of Manitoba, water contains high levels of dissolved minerals, which means your plumbing has to handle steady exposure to calcium and magnesium every day. But how does this help answer the question, "Why do pipes make noise?"
These minerals can stick to the inside of your pipes; over time, they form thick deposits that restrict the flow and increase pressure. The imbalance often causes hissing, squealing or banging sounds as water forces its way through tight spots.
To slow mineral buildup, many homeowners install a water softener.
Worn Parts and Loose Fixtures
Not all plumbing noise comes from behind the walls. Sometimes, it starts right at the fixture. A worn-out washer inside a faucet or shower head often creates a high-pitched squeal as water flows through. Over time, washers lose their shape and begin to vibrate under pressure.
Loose components like faucet handles, spouts, or shower heads also add to the noise. When water moves through, those parts shake and create a rattling or buzzing sound.
Replacing a worn-out washer or tightening loose components usually stops the noise right away.
