The average water heater works continuously to provide a household with hot water when they need it. This continual work puts stress on the system and can cause it to fail prematurely if you don't maintain it and call for repairs when something seems wrong. Before you call a plumber, get to know these common water heater signs and what they mean for your unit. Fluctuation in Water Temperature: If you get water that fluctuates between being too hot or too cold, it might mean one of the heating elements is failing. It can also mean that your water heater has lost efficiency with age, and can't provide the hot water you're used to. Leaks: A leaky water heater doesn't always require replacement. Sometimes, you might have a faulty temperature and pressure relief valve that's the issue. Other times, it may be something as simple as a bad gasket. Discolored Water: If you notice brown water, it may mean that the tank is corroded or you have a failing anode rod. A corroding tank requires replacement, while an anode rod is easy to swap out. Strange Noises: As water heaters age, sediment builds up inside the tank, which can lead to strange sounds coming from the tank. You might hear rumbling, cracking, or popping sounds. Most times, this problem is fixed by flushing the tank to remove the sediment. If you hear a high-pitched whining noise, it could be scale build-up on the heating elements. You can fix this also by flushing the tank and cleaning off the scale. If you have other questions or concerns about your water heater, call the experts at Cajun Plumber for a consultation.
