Why Do Water Pipes Rattle And How To Fix Rattled Water Pipes?

If you’re at home, you want your plumbing system’s tubes to deliver hot and cold water to all areas of your home whenever you want it. Whether baking in the kitchen, relaxing in a warm bath, cleaning in the washer, or flushing the toilet, water supply and distribution is vital to daily life. Unfortunately, these pipes aren’t flawless, and you may notice that a few of them begin to produce noises after a while. These odd plumbing sounds may even startle you. So you might be thinking about why do water pipes rattle? Keep on reading to know all about ratting of pipes.

Is It Normal For Pipes To Rattle?

It’s usual for water pipes to rattle in old houses or residences that haven’t got adequately maintained, but hearing noises from your water pipes isn’t a good indicator.

These sounds typically suggest that something is amiss. In the case of plumbing troubles, these problems do not resolve themselves but worsen with time. As a result, if you start hearing loud thumps, thuds, or other noises emanating from the water pipes, we urge that you contact the plumber straight once.

Why Do Water Pipes Rattle?

Water pipes are indeed an integral component of most buildings’ plumbing systems. They often get built of metal, PEX (cross-linked polyethylene), or other nonmetallic pipes. They transport or remove water as needed. Usually, the drainage system gets made up of various pipe materials.

Water pipes can run through or over walls, roofs, and floors. Pipes that are exposed are easier to check and repair. However, most plumbing is hidden within the framework of the building, making upkeep difficult and costly. Plumbing that runs through or is flush with structural components is a common source of rattles and vibrations.

So why do water pipes rattle? Identifying what is causing the noise and where it is happening is simply one aspect of the problem. It will be more challenging to determine what triggers the pipes to make unsettling noises. Here are some probable causes of a mixture of sounds produced by pipes.

  • High Water Pressure

When taps are opened or closed, or the toilet is flushed, the high water pressure causes leaks, and toilets continually empty. Also, faucets spew, and pipes slam, knock, rattle, vibrate, and whistle squeak.

The excessive water pressure causes pipes to be loud. It can also cause damage to water pipes, joints and elbows, connectors, fittings, and even washers and hot water tanks, resulting in costly repairs and waste of water

You may believe that high water pressure is essential for a pleasant shower or better water flow. On the other hand, the correct water pressure will still provide a cleaning force; it simply won’t rip the skin off as a water pick.

  • Loose Pipes

Water pipes can generate noise when they’re not correctly attached or adequately supported. Vibrating water pipes are frequently unsecured or not firmly secured. Water pipes that rattle often lack support or attach brackets. Water rushes through to the tubes to fulfill the demand when taps, toilets, or machines are opened, flushed, or triggered.

Also, water force and movement cause pipes to flex and move, resulting in vibration, rattle, boom, or squeaking. The same thing can happen whenever the water gets turned off, and the pipes return to a resting position. Pipes that are not correctly secured will create more noise than those that are.

Why Does your Toilet Keep Clogging? Here is the reason. 

  • Trapped Air

Taps can splutter, and pipes might vibrate, bang, or rattle if the air becomes trapped in them due to recent repairs or a malfunctioning valve. If trapped air builds at a faucet, it can cause an air hammer. Because the contained air seems to be under pressure from the water, it shoots out like an air pistol when the tap gets quickly opened.

The abrupt release frequently causes water to leap against locked appliance valves and taps throughout the building, resulting in a boom from the water pressure. Furthermore, water flow may cause pipes to shift, adding a rattle, bang, or vibration to the cacophony.

  • Water Hammer

A water hammer occurs when a tap gets abruptly turned off, resulting in a bang followed by softer bangs for a brief period. Because the water in pipes is incompressible, closing the valve or faucet causes the water to smash against the valve. The liquid’s momentum and velocity produce a hydraulic shock or hammer.

The water slams against the abruptly closed tap, causing it to withdraw and creating a vacuum at the shut valve. The vacuum draws the water back against the valve with a softer boom. This cavitation will continue with increasingly quieter booms till the water stops flowing.

  • Temperature Changes

Pipes may expand when exposed to hot water, and they can shrink when exposed to cool or cold water. Warming or cooling pipes may rub across structural construction elements or brackets, causing vibrations, rattle, or squeak.

It is especially the case for ductile and malleable copper pipework. However, similar noises may get made by flexible plastic tubing such as PEX.

How to Fix Rattled Water Pipes?

Now you know why do water pipes rattle. To fix the rattling of pipes, it is simple to quiet vibrating and shaking water pipes by adding extra supports and brackets covering pipes.

They must come into touch with other components and insulate them. Installing a water hammer stopper is another viable do-it-yourself plumbing noise-control solution.

Final Thought

To sum up, the rattling of pipes sometimes startled you, but above we’ve discussed five reasons why the water pipes could be loud, but there could be others. It may be too difficult for a home to troubleshoot and repair.

It would be best if you now had a better understanding of what causes noisy water pipes and also how to mute them. If something is keeping you awake at night, we’d be happy to investigate and address it for you.
