Bad water heater noise can be incredibly frustrating. Whether it's a loud bang when the water is turned on or a constant humming that's driving you up the wall, it can be difficult to deal with. If your water heater is making several strange noises, it's important to understand what is causing the problem and how to fix it.

Let us now understand bad heater noise and how to deal with them properly:

What Bad Water Heater Sounds Are Like

The most common sounds you may hear coming from your water heater include the following:

Humming

If the water heater is making a humming noise, it could be due to a notable build-up of sediment in the tank. When the sediment is heated, it can create a humming noise. To fix this problem, you'll need to flush the sediment out of the tank and make sure the heating elements are working properly.

Hissing

A build-up of pressure in the tank can cause hissing noises. The pressure can be caused by various things, such as a faulty pressure relief valve or a problem with the thermostat. It's important to take action and fix the underlying problem. Otherwise, the water heater could explode, causing serious damage to your home.

Hammering

If your water heater is making a hammering noise, it could be due to sediment build-up in the tank. The high pressure can cause the water to knock against the sides of the tank, which creates a hammering noise. It's important to have it removed, and you can do this either yourself or by calling a plumber to do it for you.

Screeching

This noise is usually caused by a problem with the heating element. If it's not working properly, it can create a high-pitched screeching noise. You must clean the sediment out, which you can either do yourself or by hiring a plumber to do for you.

Ticking

Ticking noises can be annoying, and this is due to the expansion of metal in the water heater as it heats up. When water is heated, it expands, and the metal in the water heater expands with it. If the noise is accompanied by other strange odours, it could be a sign of a major problem.

What Bad Water Heater Noise Entail

If you ever hear strange noises coming from the water heater, investigating is a must. It's not worth waiting to see if the noise stops, as it could be a sign of a major problem. While some noises are simply the result of the normal operation of the water heater, others can indicate a problem that must be addressed.

How to Fix Bad Water Heater Noise

First and foremost, it is important to investigate the cause and what kind of sound the water heater is making. This way, you'll be able to determine how to fix the issue. Keep in mind that DIY solutions are not recommended and that it's best to call a plumber or water heater technician to make the necessary repairs.

Conclusion

Now that you're well aware of these factors, you should understand what it means to deal with bad water heater noise. Be sure to investigate the issue as soon as possible to avoid any serious problems down the road.
