Water Heater Gurgling: An Annoying Issue Explained

Gurgling water heaters can be an annoyance that disturbs the serenity of your home. This gurgling sound is typically caused by air trapped inside the water tank, and it occurs when the heated water rises, pushing the air upwards. As the air accumulates at the top of the tank, it forms air pockets that burst, creating the gurgling noise.

Solving the Gurgling Issue: Step-by-Step Guide

1. Turn Off the Water Supply: Begin by shutting off the cold water supply to your water heater. This is usually a valve located near the top of the water heater.
2. Drain the Water Heater: Connect a hose to the drain valve at the bottom of the water heater and direct it to a drain. Open the valve and allow the water to drain completely.
3. Remove the Pressure Relief Valve: Use a socket wrench to carefully unscrew the pressure relief valve located at the top of the water heater. Note that some water may leak out during this step.
4. Let the Air Escape: With the pressure relief valve removed, turn on the cold water supply to the water heater again. This will allow air to escape through the opening where the valve was removed.
5. Replace the Pressure Relief Valve: Once the gurgling sound subsides, indicating that most of the air has escaped, turn off the water supply. Screw the pressure relief valve back into place.

Tips and Expert Advice

• Flush the Water Heater Regularly: Draining and flushing the water heater once a year can help prevent sediment buildup, which can contribute to gurgling.

• Inspect the Dip Tube: The dip tube is a pipe that carries cold water into the bottom of the water heater. Check if the dip tube is damaged or clogged, as this can lead to air being trapped inside the tank.

• Consider a Thermal Expansion Tank: A thermal expansion tank is installed on the cold water supply line and helps absorb the pressure created by expanding water. This can reduce gurgling and other noises.

By following these steps and expert advice, you can effectively resolve the issue of a gurgling water heater and restore peace to your home.
