A water heater is a crucial appliance in any household, providing hot water for showers, laundry, and dishes. However, like any other appliance, it requires regular maintenance to keep it functioning properly. In this article, we will discuss the common issues that can arise with a water heater, how to fix them, and when it’s time to replace the unit. We will also provide guidance on selecting the right size water heater for your household and the average cost of water heaters and their replacements.
Common Issues with Water Heaters
No Hot Water: The most common issue with water heaters is that they stop producing hot water. This can be due to a faulty heating element, a malfunctioning thermostat, or a tripped circuit breaker.
Leaks: Leaks can occur due to a damaged tank, a worn-out valve, or a loose connection. Leaks should be addressed immediately to prevent further damage and potential flooding.
Strange Noises: Water heaters can make strange noises due to sediment buildup or a malfunctioning heating element.
Discolored Water: If the hot water appears discolored, it may be due to sediment buildup or a rusted tank.
