Let's get the scenario in place. Imagine you are taking your shower hot and, within a few minutes, you hear something screaming out of the heater. On the other hand, there's no need to panic because it's a frequent plumbing issue. However, on the contrary, it's something to ignore. In addition to the fact that it can be annoying, a blaring water heater is only the beginning of the iceberg. If the problem is not resolved, it could cause a larger, more expensive, and more risky issue.



What causes a loud water heater?

The most frequent reason that your hot water is "screaming" when in use? The water heater is operating under pressure. Each water heater comes with a safety feature known as a pressure relief valve. This valve can be opened to allow hot water to flow through when pressure levels are higher than the limit. If it's operating well, you won't even be aware that the valve for pressure relief is operating - besides the presence of water at the bottom of your water heater.

The issue is when the valve for pressure relief doesn't function as it was intended. If the valve for pressure is broken or damaged due to any reason and fails to open, pressure will rise in the tank that holds hot water and have no way to escape, resulting in the high-pitched sound that you hear.

The reason why pressure that is too high can be dangerous

While the sound itself can be annoying, it could also lead to serious issues that could cause you to scream if it's not addressed. If the pressure builds within the tank and isn't released, eventually, something serious is likely to occur. This could result in the water heater leaked, cracking, or, in the most likely scenario, an explosion.

It's important that you pay attention to water heaters that make a loud screeching sound.
