Noisy Water Heater: A Possible Sign Of Problems


Although not always the case, a noisy water heater can be a sign that there's a problem. While improper maintenance and the age of the heater often are at the root of the problem, it helps to know why water heaters make different noises, as well as when you may need a plumber's help to fix what's wrong.

High Water Pressure

If your water heater makes a high-pitched noise, it's not something to ignore as the water pressure inside the tank may be too high. Although your water heater should be equipped with a pressure relief safety valve that is supposed to open and release water when too much pressure builds up in the tank, if the valve fails, you'll need to call a plumber. Too much pressure inside the water tank over time can cause the water heater to leak, crack, or even burst.

Accumulation of Sediment

A rumbling noise coming from your water heater is usually a sign of sediment accumulating at the bottom of the tank. This happens as a water heater gets older, causing the heater to become less efficient.

As more sediment builds up in the tank, more of the heat that should be heating your water goes up the chimney instead. The buildup of sediment can also shorten how long the tank will last, causing the water heater to fail sooner than it would otherwise. When the heating element overheats, it can burn out. But simply flushing the tank from time to time gets rid of damage-causing sediment, saving you energy and the need to replace the water heater sooner than later.

Mineral Deposits

A water heater can make crackling noises when water gets trapped under lime deposits that are created by hard water. A plumber can solve the problem by flushing the water heater with an acidic compound.

If you live in an area with hard water that has a high mineral content, you also may want to consider hiring a plumber to install a water softener. Without a water softening system to remove hard metals from the water, the mineral deposits that hard water leaves behind can damage pipes and appliances–including your water heater–through which water travels.


If you have a gas water heater and hear a sizzling noise, either condensation or a leak may be the cause of the problem. Drops of water hitting a hot surface are responsible for the noises you hear. When a leak is the problem, you may need a plumber like Johnny Pipewrench LLC to repair or replace the element that is leaking.
