An adult listening for strange noises.

Do you hear strange noises coming from your plumbing? If so, you're not alone! Many people hear weird noises coming from their pipes, and they often wonder what they mean. It might be something as simple as a water droplet falling from a faucet, or it could be something more serious like a gas leak. However, instead of ignoring these noises, it’s best to know what they mean in case you need any repairs.

In this blog post, Patterson Plumbing & Heating, Inc. will discuss the most common plumbing noises and what they mean. By understanding these sounds, you'll be able to troubleshoot any issues that may arise with your plumbing system. Keep reading to learn more!


One of the most common plumbing noises is a knocking sound. This noise is usually caused by a water hammer, which occurs when water flowing through your pipes is suddenly interrupted. A water hammer can damage your pipes and fixtures, so it's important to fix this issue as soon as possible. If you hear a knocking noise coming from your plumbing, check to see if your valves are closed properly or if there is a clog in your pipes.

Knocking can also be a sign that your water pressure is too high. While the sound won’t be a loud knocking, you will hear somewhat of a tapping noise when your water is running.


One common noise you might hear is dripping. This is usually caused by a water leak or air in the pipes, which can waste a lot of water and increase your utility bills. You should fix any leaks as soon as possible to avoid further damage and a scary water bill.


Another noise you might hear is gurgling. This could be caused by a clog in your drain or vent pipe. Typically, when your drain or vent pipe is clogged, water isn’t able to flow freely the way it normally would. This results in air bubbles in your pipes, causing the gurgling sound. If the clog is severe, it could cause sewage to back up into your home. This is a dangerous health hazard, so it's important to call our team right away to clear the clog and repair any damage.


Hissing noises are often indicative of a gas leak. Gas leaks can be very dangerous because they can cause fires or explosions. If you smell gas or hear a hissing noise, you should evacuate the area immediately and call your local utility company.

Hissing can also indicate that your water pressure is too high, similar to the knocking/tapping sound you might hear. If this is the case, it’s important to schedule an appointment with Patterson Plumbing & Heating, Inc. before you cause too much stress on your pipes.


Squealing or whistling noises usually occur when water is being pushed through a small opening. Your plumbing components can go through general wear over time, especially if there is mineral buildup in your pipes due to hard water. This can cause serious damage to your plumbing system, so it's important to have a professional take a look at your pipes and make any necessary repairs.
