Why Is My Water Heater Cracking & Popping?

Plumber inspecting a water heater

When it comes to home appliances, the water heater is a crucial one that homeowners use every day. It provides hot water for showers, cleaning, cooking, and more. However, like other appliances, it can sometimes malfunction and cause various handling problems. One of the most common problems is strange noises such as popping, cracking, or banging sounds. In this blog, we will discuss why water heaters make these noises and what can be done to fix it.

1. Sediment Buildup

One of the most common causes of a noisy water heater is sediment buildup. Over time, minerals such as magnesium and calcium can accumulate and settle at the bottom of the tank. When the mineral deposits come into contact with the heating element, they create a popping sound. To rectify the problem, a professional plumber should drain and flush out the sediment.

2. Thermostat Issues

Another common cause of water heater noise is thermostat issues. A malfunctioning thermostat can cause the heating element to overheat and expand, causing the tank to crack or pop. To fix this, a professional plumber can repair or replace the thermostat.

3. Loose or Faulty Heating Elements

Heating elements inside the water heater can become damaged or loose over time, which can lead to popping, banging, or other sounds. Call in a professional plumber to repair any damaged heating elements to alleviate the noise.

4. High Water Pressure

If the water pressure is too high, it can cause vibrations in the water heater, resulting in loud noises. Professional plumbers can install a pressure regulator to reduce the pressure and alleviate the noise.

5. Age

Water heaters become less efficient over time, and their components can deteriorate, leading to strange noises. If you notice cracking or popping sounds coming from your water heater that’s 10+ years old, it could be time for a replacement.
