Three Causes of Noisy Water Heaters

When the water heater in your Schick, IL, home starts to make noise, you never want to ignore it. Some issues that are left unaddressed can turn into big problems down the road. Here are three reasons your hot water tank is making noise.

1. Sediment in Your Water Heater
Over time, hot water tanks collect sediment. When the sediment isn't regularly flushed, you could hear bubbling or cracking sounds coming from your tank. These noises occur because the water trapped between the sediment layers heats up and forces its way through.
Most water damage mitigation specialists suggest that you do a water heater flush at least once a year. The flush will ensure that you clean out the sediment and extend the life of your plumbing fixture.

2. Loose Heating Element
If you constantly hear a humming noise coming from your hot water tank, it likely means that you have a loose heating element. The flowing water around the element causes vibrations, which is responsible for the humming.
While there isn't much to worry about with a loose heating element, you can have a plumber tighten it if the noise is driving you crazy.

3. Leak in the Hot Water Tank
A hissing sound coming from your water heater usually indicates a leak. The sound is from the water or steam escaping from a hole in the unit or one of the pipes. Look for water stains around the unit to help identify the problem area. Ensure that all connections are tight and secure. If you can't safely stop the leaking, immediately call a plumber to come out and repair or replace the unit.
A hot water tank can make a lot of unsettling noise. Thankfully, understanding the different reasons it's making noises can help you better understand what is happening with your fixture and how to fix it.
