Why is my water heater making funny noises?

These days every home has a water heater installed in their home as it offers comfortable and relaxed life to the homeowners. But sometimes, when you turn on the water heater, you will hear a certain amount of noise coming from the unit. These sounds can be in many forms, like hisses, whistles, pops, and bangs.


The water heater repair in Temecula experts states that most of the homeowners think that this sound indicates the unit is about to explode. But this is absolutely wrong as this sound shows sediment build-up inside the water heater tank. That means the homeowner has to call the water heater repair in Temecula professionals for the inspection and the fix.




Now the question is, what are the common causes due to which water heater is making noises? So, let's deep dive into the causes so that, as a responsible homeowner, you can call the experts and fix the issue: -

  1. Popping

If your unit is making a popping noise, it is due to sediment build-up. This build-up is a prevalent issue or occurrence, especially when you are living in an area having hard water. When the unit takes hard water inside during the heating process, the steam bubble that forms under the sediments burst, offering popping sounds.

To solve these issues, you can flush the water heater regularly or drain the tank to remove all sediments.


  1. Rattling or knocking sound

If you hear that your unit sounds like a big maraca, these sediments are floating around inside the water tank. When these sediments float, they knock against the tank and offer this sound.


  1. Crackling or hissing sound

This noise is pervasive in electric power water heaters. However, this sound from the unit is not a big deal, but if the noise doesn't stop, then the reason for this noise is something obstructing the unit's heating element. In this case, on your behalf, you first drain the water heater tank or call water heater repair in Temecula professionals to inspect the unit.


  1. Humming sound

The humming sound from the unit is due to a loose heating element. The loose element of the water heater makes water vibrate, because of which it offers a humming sound. To solve this issue, you must tighten the heating element, or if it is not your cup of tea, then calling an expert will be a wise decision. But ensure to pay attention to the problem; otherwise, the result can be dangerous.


  1. Whistling sound

If your water heater is whistling or some high-pitched sound, it is basically due to water under pressure which is entering inside the water heater with force. The reason is the unit valve needs to be fully opened. To solve this issue, you have to listen to the whistling location, and once you get to know which valve is creating the sound, you have to replace it.

Many homeowners don't know about water heaters; in that case, calling a water heater repair in Temecula expert will be the right choice.


The bottom line

These are some of the reasons why the water heater is making noises. So, if your water heater is also suffering from these types of sounds, ensure to take action quickly to prevent further damage.
