Common water heater problems can range from minor annoyances to major inconveniences. One prevalent issue is a lack of hot water, often caused by a malfunctioning heating element, a faulty thermostat, or sediment buildup in the tank. Another common problem is water leakage, typically due to a damaged or corroded tank. Additionally, strange noises such as popping or rumbling may indicate sediment buildup or a failing heating element. For these issues, professional water heater repair services are often necessary to accurately diagnose and fix the problem.
