“Why Is My Water Heater Rumbling?”

Water Heater Rumbling

Your water heater is making an odd noise. It’s loud, disruptive, and alarming every time it happens. If you’ve heard this sound happening for a while and you’ve just hoped that it will go away, we’re here to tell you that it won’t… at least not without professional care.

Your water heater accounts for nearly 17% of your home’s overall energy usage. This means that it’s working harder than any other appliance in your home. If you don’t have a great water heater in Stamford, CT, then you need to schedule an appointment with our team members.

What’s Causing That Noise?

Let’s get to the bottom of this. What’s going on that’s making your water heater make odd sounds.

Sediment Build-Up

If you’ve lived in Stamford for a while, then you know that we struggle with hard water coming from our municipal water supply. You might notice that you have water that leaves you feeling like you have a layer of film all over your body, dry hair, or brittle nails. These are all issues that stem from hard water. Another negative side effect is the strain on your plumbing.

Your home’s plumbing starts to build a layer of sediment over time if it’s under the pressure of hard water. The sediment settles at the bottom of your water heater and creates a layer that’s hard for any water moving through your system to pass. If this is happening in your water heater, you might start to notice some rumbling sounds. A good flush can be the first step in getting rid of these sounds.


Let’s talk about another common sound you might hear coming from your water heater if things are going wrong—sizzling. If your water heater starts to leak, the hot water coming from the tank is going to make a sizzling sound upon contact with an outside space.

Leaks are something that you want to watch out for because they can be destructive to a home. They have the potential to lead to water damage. They can even be dangerous to your family members or pets if the hot water comes in contact with a person.

An Old Tank

Have you noticed that you have poor water flow throughout your home? This could be due to an old tank. Water heaters can last quite a while if you equip your home with the right unit. This doesn’t mean that they’re going to last forever though. If you have an old tank, it can start to produce a variety of problems. The most common is a humming noise caused by your water heater shaking.
