How to Stop the Noise Coming from Your Water Heater

Sometimes, taking a shower is your only me-time, and of course, you want it to be peaceful and quiet as much as possible so that you can enjoy the moment. But, here comes the noisy water heater ruining your moment in the shower. Before you can finally enjoy a peaceful time in your bathroom, you must know how to stop the noise from your water heater first. Fortunately for you, we’ve listed some of the things you can do to prevent and stop the noise from your water heater.

Why Is Your Water Heater Making a Noise?

First off, you must know why your water heater is making a noise. Typically, a water heater is making noise because of sediment buildup in the bottom of the heater. When you hear a popping sound, that just means that the hot water is bubbling up through the sediment in the bottom of the tank.

In some cases, the water heater is making a noise because of the fluctuations in water pressure, producing a ticking sound. Sometimes, the ticking noise is attributed to loose pipe straps that hold the hot water line coming out of the water heater.

If you hear a sizzling sound, that just means that the water is leaking from the tank and onto the hot burner assembly. If the noise from the water heater is a hammering or knocking sound, it means that the water flow is being stopped suddenly.

How Can You Prevent the Noise from Your Water Heater?

Since sediment build-up is the most common cause of water heater noise, we’ll discuss how you can prevent this. Like any fixtures and appliances in your home, your water heater also needs some maintenance.

Part of your water heater maintenance is that you should take out the bucket’s worth of water from the tank every 3-4 months. However, you should be careful while doing this because the water can be very hot and scalding. By taking out the water from the tank periodically, you can slow down the build-up of the sediment. You must also flush your water heater out once a year so that you can flush out the sediments. It will also be helpful if you can install a water softener in your home. Installing a water softener will help eliminate the sediments that are building up in your tank.

It’s crucial to perform this maintenance work on your water heater to prevent sediment build-up. Once you ignore the sound and the sediments in your tank, your water heater may encounter a more severe problem like rusting out and leaking. If this happens, your only option is to replace your water heater completely.

How to Stop the Noise from Your Water Heater

The only way to stop the noise from your water heater is to address the cause of the noise. It may be hard to determine the problem if you are not familiar with the noise your water heater is making. While you can turn off the water heater to stop the noise, it will only be a temporary solution that is not practical since you need a water heater. The best solution is to call for a water heater repair service to determine and fix the problem right away.


A noisy water heater can create more inconvenience if you just let it pass. Don’t wait for your water heater to break down completely; you should call for a plumber right away once you start hearing unusual noises from your water heater.
