If you’ve ever been startled by a loud banging or rattling sound from your pipes, you’re not alone. Noisy water pipes can be really annoying, especially when they wake you up in the middle of the night. The good news is, it’s usually something you can fix yourself. Let’s break down why your pipes are making that noise and what you can do to stop it.
Why Are My Water Pipes Making Noise?
There are a few reasons why your pipes might be noisy. Understanding the cause is key to fixing the problem. Here are the most common reasons:
- Water Hammer: This is probably the most common culprit. It happens when water suddenly stops or changes direction, causing a shockwave. The result? A loud banging noise.
- High Water Pressure: If the pressure in your pipes is too high, it can make a hissing or banging noise.
- Loose Pipes: Sometimes, the pipes just aren’t secured properly. This can make them rattle or vibrate.
- Air in the Pipes: Trapped air can cause a vibrating or banging sound, especially when you turn on a tap.
- Worn Out Washers: If the washers inside your taps or valves are worn out, they can make a whistling or squealing noise.
Now that you know what might be causing the noise, let’s go through some practical fixes.
How Can You Fix Water Hammer?
Water hammer happens when a fast-moving column of water hits a valve that’s suddenly closed. This causes a shockwave that travels through the pipes, making that banging sound. Here’s what you can do:
Drain Your Plumbing System
Sometimes, air chambers in your plumbing can become waterlogged, making water hammer worse. Draining your system can help.
- Turn off your main water supply.
- Open all your taps, starting from the top floor and working your way down.
- Let all the water drain out.
- Once everything’s drained, turn the water back on and close the taps in reverse order.
This simple trick can sometimes reset the air chambers, reducing or even stopping the noise.
Install Water Hammer Arrestors
If draining doesn’t work, you might need to install a water hammer arrestor. These small devices absorb the shock when water suddenly stops. You can buy them from most DIY stores. If you’re handy with plumbing, you can install them yourself. Otherwise, a plumber can do it for you.
How Do You Reduce High Water Pressure?
High water pressure can cause pipes to vibrate or make a loud rushing sound. It’s not just noisy—it can also damage your plumbing over time.
Check Your Pressure
Get a water pressure gauge from a hardware store and attach it to an outside tap. Your pressure should be between 40 and 60 psi. Anything higher might be causing the noise.
Install a Pressure Reducing Valve
If your water pressure is too high, installing a pressure-reducing valve can help. This valve automatically lowers the pressure to a safe level. It’s best to get a professional to install this, as it involves cutting into the main water line.
What If My Pipes Are Loose?
Loose pipes can rattle against walls, floors, or each other when water flows through them. Here’s how to secure them:
Inspect the Pipes
Look at the pipes, especially in your basement or under sinks. Try to pinpoint where the noise is coming from.
Use Pipe Clips or Brackets
Secure the pipes with pipe clips or brackets. Make sure they’re snug but not too tight. This should stop the rattling.
Add Padding
If the pipes still make noise, add some foam insulation around them. This cushions the pipes and can reduce vibration.
How Do You Get Rid of Air in the Pipes?
Trapped air can cause banging or a loud vibrating noise when you turn on the water. Here’s how to fix it:
Flush Your System
- Turn off your main water supply.
- Open the highest and lowest taps in your home.
- Let the water run out completely.
- Turn the water back on and let the taps run until the noise stops.
Bleed Your Radiators
If you’ve got central heating, air in the system might be causing the noise. Use a radiator key to bleed them and let the air escape.
What About Noisy Taps and Valves?
If you hear a whistling or squealing noise when you turn on a tap, it could be due to worn-out washers or faulty valves.
Replace Washers
Take the tap apart and check the washers. If they look worn or cracked, replace them. It’s a quick fix that can make a big difference.
Check the Valve Seats
Sometimes the valve seat can wear down, especially in older taps. You can smooth it out with a seat grinder or get a plumber to replace it.
When Should You Call a Professional?
While some noisy pipe issues are simple to fix, others can be more complex. If you’ve tried the DIY fixes and the noise is still there, or if you’re not confident working with plumbing, it’s best to call a professional. They’ll have the tools and experience to diagnose and fix the problem.
Can Noisy Pipes Cause Damage?
Yes, if left unchecked, noisy pipes can lead to serious issues. Water hammer, in particular, can eventually cause leaks or even burst pipes. High water pressure can wear down joints and connections. Don’t ignore the problem—address it as soon as you notice it.
Final Thoughts
Noisy water pipes can be a real pain, but with a bit of know-how, you can usually sort it out yourself. Start by figuring out what’s causing the noise, then try the most straightforward fixes. If the problem persists, don’t hesitate to get professional help. Keeping your plumbing in good shape will save you a lot of hassle down the line.
If you’re not sure where to start or feel uneasy about tackling the problem yourself, a quick call to a local plumber can put your mind at ease. After all, it’s better to sort it now than to deal with a burst pipe later.
