Are Noisy Water Pipes Dangerous?

We’ve all experienced weird sounds at night in our home, including bumps, crackles, clinks, and wobbles. You can safely disregard the majority of these noises. However, pay attention if your water pipes start making pounding noises. They can be a sign of a severe plumbing problem.

The majority of the time, random little noises are not harmful. However, suppose something is loose or broken, and your pipes are rattling loudly and continuously. In that case, it may be a sign that they are in danger of breaking.

What Causes Obnoxious Banging Sounds in Water Pipes?

“Loud banging” or “banging noises” are homeowners’ first and possibly most typical complaints regarding their pipes. If your home’s pipes are banging, you may have a problem with water flow or high water pressure, which is frequently resolved with a pressure reduction or pressure regulator (most new homes already have these); experts refer to this as “water hammer.”

When you quickly shut off your faucet or valve, it causes a water hammer. The velocity and momentum of all that water flowing down to the exit route cause it to hit the closed-off valve point with an exceedingly loud hammering. All things considered, water hammers can and do occasionally manifest as much weaker noises in your plumbing pipes with shutdown valves, so it’s crucial to have a qualified plumber take a look to pinpoint its particular source.

A water hammer arrestor will frequently just be installed by a plumber at the proper pipe position. After a faucet is turned off, these redirect the water’s “hammer.” Another way to stop hammering noises in a house is to close the main shut-off valve and drain the entire system before turning off the water supply. If this occurs, consider your lowest faucet(s), frequently found in the cellar or on an external hose line.

They aren’t used as often and are therefore more likely to be forgotten. The air chamber’s trapped oxygen is a different cause of banging noises. If trapped air is the cause of the slamming in your pipes, then these sounds typically begin as soon as a faucet is turned on. However, you might also hear a bubbling sound as the air climbs up and out. Issues with water lines can cause air to become clogged up in pipes.

How To Stop The Noise In Water Pipes

Water hammer, a type of hydraulic shock that happens when the sealed valve on a rising water pipe abruptly closes, is the pounding noise you’re experiencing. Water rushes swiftly through your home’s pipes when your washing machine fills up until the machine valve suddenly closes when the drum is full.

The rapid water supply pummels against the wall of the pipe with a strenuous surge of pressure because it has nowhere else to go. This causes the pipes to jerk and clatter against pipe or wall outlining. As a response, you hear a series of loud bangs and possibly even sense the pressure moving the walls of your home.

Water hammer can seriously damage pipe junctions and joints, causing leaks and expensive repairs in addition to its loud noise. Or worse, the noise can be a sign of a more severe issue like high water pressure or faulty plumbing.

Fortunately, householders may frequently get rid of water hammers without hiring a specialist for a reasonable price. You can look into the situation by simply following the procedures listed below.

Examine The Air Chamber In Your Plumbing

This vertical pipe that is situated close to the water valve reduces the water hammer by acting as a cushion. When the valve closes, the air chamber softens the shock of the water and stops it from crashing on the pipes’ side loudly. A common feature of homes is the installation of air chambers within the walls; however, if the air chamber gets wet, it may not always function well.

The problem must be resolved by draining the homeowner’s plumbing system. The lowest faucet, typically in the basement or first level, should be emptied before turning off the main water valve, opening the highest tap in your home, and doing so.

In hopes of resolving the water hammer issue, the air chamber will re-fill with air rather than water. Consider having an air chamber installed by a professional if your house doesn’t already have one.

Install Water Hammer Arrestors

The air-filled cylinders in water hammer arrestors cushion the shock of an abrupt rise in water pressure that occurs when a valve closes. A shut-off valve and a water supply line are connected by screw-type connectors on most water hammer arrestors today.

Make careful you install two on the supply line for hot water and one on the supply line for cold water. To install the arrestors, though, don’t be afraid to call a plumber if you’re unfamiliar with fundamental plumbing connections.

Reduce The Water Pressure By Turning The Valve

Water hammer can occasionally be caused by too much water pressure in your pipes. In this case, adding a water arrestor or draining the water from the air chamber can only provide short-term relief.

The pressure-reducing valve in your home should be adjusted to control the pressure. Nowadays, most homes have these valves, which are frequently found near the entrance to the main water supply.

Some valves include an adjustable handle, while others need a wrench or screwdriver, based on the manufacturer. To set your valve below 50 PSI (pounds per square inch), which is adequate for most households, use the correct approach.

Additional benefits of lowering water pressure in your home include energy savings, water conservation, and perhaps even a longer lifespan for expensive automatic appliances like dishwashers, toilets, and refrigerators.

Lower The Excessive Water Pressure

Residential water lines aren’t made to adequately withstand high pressures; municipal water systems frequently keep the water in their pipes at 200 PSI or less. Consider requesting that the municipality that manages the water system in your town check the water pressure in your home if it doesn’t have a pressure-reducing valve.

Your water pressure will typically be checked by the municipality without charge, and if required, it can be lowered.

Fix Slack Water Supply Lines

U-shaped pipe straps are used by the plumber to screw water supply lines to hardwood joists or studs during home construction. The pipes may move and make noise if the straps are not secured tightly enough or if a few straps are missing.

Put an end to the pounding by using a screwdriver to tighten any loose pipe straps or by adding more pipe straps for more support. The majority of pipe straps are made of thin metal or plastic. Still, you can also get padded pipe straps that further suppress vibration.

Remember that copper pipes should never be strapped with steel or galvanized straps since the integration of the two materials might result in plumbing leaks and electrolysis.

Insulate Pipes

To prevent ice from forming on water supply lines, pipe insulation is provided in foam tubes that fit around the pipes. The pipes can be cushioned to stop them from rattling and being loose. The foam tubes are already slit end to end when they are shipped, so all you have to do to open the box is slide your finger along the slit.

After that, you can simply fit the tube over the water supply line. Typically, six-foot lengths of this type of foam pipe insulation are sold, with prices per tube varying based on density from around $3 to $8.

Why Are My Water Pipes Rattling And Shaking?

If the hot water heater’s temperature is too high, copper pipes frequently broaden as warm water passes over their metal surface. The pipe may start to move or sway as water flows through it if one of these slips, comes loose, or ultimately falls off. While most of your home’s piping is concealed behind walls, floors, or ceilings, some must be hung with fasteners.

When copper pipes transporting hot water shrink back to their original size, they can make loud noises as they scrape against a house’s joists, studs, or wall sustain brackets. If this occurs, you’ll likely hear rattling or shaking coming from within your walls. This is only the outcome of a loose-fitting pipe, so it can be resolved relatively quickly.

However, it should be fixed immediately to prevent the problem from worsening. Call a dependable plumber right away if you hear rattling or shaking in the ceiling or under the floorboards so they can take care of the problem before it becomes intolerable.

Conclusion

The shut-off valve gets slammed against when water is gushing and then abruptly stopped because the rushing liquid has nowhere to go. Water hammer is the term for the subsequent loud, thudding sound.

Water hammer is not only obtrusive but may also harm the water pipe’s connections and joints. Get a plumber to look at everything immediately to prevent further damage because broken pipes can result in significant water damage.
