What to do About Your Noisy Water Heater

2/3/2020 (Permalink)

Your water heater is the lifeblood of your home. It controls the flow of water to your sinks, tubs, and major appliances while allowing you to regulate the desired temperature for drinking, bathing, and other needs for you and your family. Like any other major appliance, problems can occur over time, and repair and/or replacement costs can skyrocket when not properly maintained. Fortunately, simple observations may be enough to help you diagnose a potential problem as it arises.

Identifying Problems Through Listening

Water heater noises are varied and can stem from several potential problems. Some issues can be small and easy to fix yourself, while others may require professional help. Note the following common occurrences and their sounds:

• Partially-closed valves – Water line valves that are partially closed forces water to push through smaller openings, creating a screaming sound. Ensure all valves are completely open when hearing this noise.
• Sediment buildup – Sediment naturally forms over time around element tubes and traps water beneath the layers, indicated by a crackling sound. The element should be cleaned, or replaced if the noise persists
• Loose sediment – At times, sediment deposits can be stirred inside your tank when water is flowing through, causing a rumbling noise. Using a deliming solution during a water heater flush should solve the problem.

Additional Maintenance Notes

Water heater maintenance is one of the best ways to prevent leaks and premature breakdowns. The buildup of sediments and other minerals are a major cause for issues, particularly if you have hard water. Installing a water softener, and regular flushing and cleaning of the system can help prevent long term issues. If leaking does occur, always consult a water cleanup and mold remediation professional to ensure there is no extensive damage to your heater and the surrounding area. The cost of regular maintenance often pales in comparison to that of a major repair or replacement, so taking the time to observe your heater and keep it clean can save a fortune in the long run.
