Let's imagine. You are taking your shower hot, and then, before you know it, there is a sound like something is screaming at the temperature of your water heater. On one side, don't be concerned because it's a typical plumbing issue. However, on the other hand, it's definitely not something to be ignored. Aside from the fact that it can be annoying, a blaring water heater is only the beginning of an iceberg. If it's a problem that is not resolved, it could cause a larger, more expensive, and more dangerous issue.

What causes a loud water heater?

The most typical reason why your hot water is "screaming" when in use? The water heater is operating under pressure. Each water heater comes with the safety feature of the pressure relief valve. It is opened and allows hot water to flow through when pressure levels are higher than the threshold. If it's functioning correctly, you might not even be aware that the valve for pressure relief is operating - besides some water that is still on the bottom of the heater.

The issue is when the valve for pressure relief is not functioning as it should. If the valve for pressure is damaged or stuck due to any reason and is not able to open, pressure builds up in your hot tank and has no escape route resulting in the high-pitched sound that you hear.

The reason why pressure that is too high can be dangerous?

Although the sound itself is annoying; however, it can also trigger severe issues that can cause you to shout in the event of not being diagnosed. If the pressure builds in the tank and cannot be released, then eventually, something terrible is bound to occur. It could be the water heater leaked, cracking, or, in the worst-case scenario, an explosion.

It's important that you pay attention to the sound of a water heater noise that is screeching.
