Here’s Why Your Water Pipes Are Always So Noisy

What’s that noisy knocking, whistling, and screeching at all hours in your house? If it isn’t a poltergeist it’s probably your water pipes. Even if you don’t mind the noise and think it adds a little character to your home, you risk long-term and costly damage if you decide to ignore noisy plumbing.


Here are the 5 most common causes of noisy pipes, and how to deal with them:


1. High Water Pressure

If it’s a constant banging and screeching you hear it could be that you have the water pressure on too high. High water pressure is not only noise and potentially harmful to your plumbing, but can damage appliances connected to your water supply as well – like washing machines and dishwashers.


You could consider installing a water pressure gauge and regulator to manage this. Proper equipment can be found in most hardware stores, and installation is generally doable on your own. However, it’s best to get a professional to ensure everything goes smoothly.


2. Loose Pipes

Rattling and cackling can come from loose plumbing – as water rushes through the pipes, anything not securely fastened will shake and sway, hitting walls or other pipes and causing the noise. Additionally, the constant wear and beating will damage pipes and cause leaks.


To fix this, you’ll have to identify which pipes are loose in order to secure them. However, this can be a bit tricky to do on your own, especially for plumbing within walls or ceilings, so depending on the location of the loose pipe, you could consider hiring an expert plumber to fix the problem.


3. Water Hammers

The thudding knocks you hear could be caused by water hammers – water rushing and slamming into shut-off valves of your plumbing when running water is turned off suddenly. Normally, water hammers are prevented by the air chamber near every faucet. But over time, the air chamber will lose its efficacy as it gradually fills with water.


Besides the noise, the constant wear and tear of rushing water can potentially damage the plumbing – pipes, joints, and connections.


A simple fix is to reset your air chamber; first, shut off the main water supply of your house. Then, drain all the water from your pipes by opening all the faucets and letting them run dry. After that, turn on the water again, and your air chamber should be replenished. Otherwise, you can consider installing a water hammer arrestor that can be found in most hardware stores. However, this is a more complicated process that’s best left to experts if you’re not big into DIY.


4. Worn Hardware

Screeching and whistling at certain areas of your plumbing – perhaps a faucet or the toilet after flushing – can indicate that you have worn components in your pipes. If it’s individual faucets that whistle; whistling toilets can also be a sign of a worn ballcock valve. These issues are easily remedied by replacing these worn parts.


5. Obstructed Pipes
