A water heater that works normally might make a gentle whirring or humming noise. However, louder and more alarming noises could mean something is wrong with it. Learn about the strange sounds that often indicate water heater problems.
Popping
Over time, sediment can build up at the bottom of your water heater tank. Steam bubbles then force their way through the crust that the sediment creates. The force of the steam coming through the crust makes a loud popping noise.
Rumbling
Sediment buildup also creates layers that shift during heating cycles. As the layers shift, the water heater will make a rumbling noise. This problem lowers your appliance’s efficiency and shortens its lifespan.
Sizzling
The components inside your water heater are hot to the touch. When water drips on them, it will make a sizzling noise. If you hear sizzling, it could mean there is a leaky valve that needs immediate repair.
Ticking
Some ticking is normal since pipes expand and contract as they heat and cool. But constant ticking can mean loose fittings that need tightening.
Hissing
If you hear a hissing noise, contact a licensed plumber right away to find and repair the cause of it. This noise typically signals that the appliance has a leak somewhere in the tank. It can also stem from a pressure relief valve releasing steam.
Gurgling
Gurgling can occur because of a couple of problems. For example, it could stem from circulation issues inside the water heater. It can also occur because of water moving through sediment or trapped air. If you do not rectify this issue, the unit will not heat efficiently and will fail sooner than expected.
Whistling
Whistling or a high-pitched whine means the water heater has a faulty pressure valve or a pressure issue. It could also occur because of restricted airflow or a partially closed valve.
Buzzing
Buzzing typically stems from an electrical problem in the water heater. Many times, the problem lies with the heating elements. Because buzzing often comes from loose wiring or faulty heating elements, it’s important to call a plumber quickly to reduce the risk of an electrical fire.
Knocking
The “water hammer effect” causes knocking. It means that the valve has closed suddenly. Without prompt repair, this issue could damage the fittings and pipes over time.
Dripping
Dripping indicates a water leak. Some of the parts that can develop leaks include the pressure relief valve, the drain valve and the water heater tank. A leak can lead to mildew growth and water damage in your home.
Boiling
If you hear boiling, turn off the unit right away, and call a plumber for help. This noise means the water heater is overheating, likely due to a faulty thermostat.
