Problematic Noises From a Water Heating Unit

Noises Caused by a Water Heating Unit

The water heater in your Imperial, MO, home may make noises while it is in use. Not every sound from this system is cause for alarm, but some of the sounds may be worse than others. Having a basic understanding of problematic noises can help you understand when to call in a water damage expert and when to leave your heater alone.

1. Crackling: The sound of crackling and popping could mean your heater has too much sediment buildup. The sound is caused by residue caking the heating element. As the heat rises, the water trapped by the sediment is forced through the buildup. Eventually, the buildup may become too thick for the heating element to work properly. You can address this problem with a water heater flush.

2. Screeching: When the valves in your heater are not set properly, you may hear a scream-like sound come from the unit. This screeching typically occurs when the valves are not opened wide enough. The buildup in pressure could eventually lead to a pipe burst or other issues.

3. Hammering: A knocking or hammering noise could be a sign that your piping has to undergo major water pressure changes. This sound may often follow the shut off of a faucet. While it may seem harmless, the rattling of the pipes could cause damage to the interior of your walls or the plumbing.

4. Humming: A low humming coming from your water heater could indicate there is a loose heating element. When the water heats up, the fast-moving particles cause the loose element to shake. If left unattended, the element may break due to the repetitive movements. However, this is an easy fix. Your professional simply has to re-tighten the coil.

You rely on your water heater to provide comfortable water to your house. Strange noises coming from this system may give you a heads up that something isn't quite right with the equipment.
