Visible Corrosion from Rust

The most noticeable sign your water heater is overheating is discolored or rusty water. This usually indicates corrosion or expiration, which are precursors of overheating. Corrosion weakens the tank, making it more susceptible to leaks and deterioration. In the case of severe corrosion, sediment buildup, or heating element damage, the tank can overheat and cause inefficiencies down the line.

Bad Water Pressure

Bad water pressure, particularly low water pressure, often indicates your water heater is overheating. The most common culprits include sediment buildup and leaks, reducing water flow and causing the water heater to work harder than usual. Additionally, a malfunctioning pressure valve can contribute to high water pressure and overheating. If you experience bad water pressure, consult a professional plumber to restore functionality and comfort to your home.

Dirty or Discolored Water

Another common sign that you need professional water heater repair is brownish or reddish water from your hot water faucets. This discoloration often indicates rust buildup, corrosion, or sediment accumulation, which are caused by overheating. Once you notice discolored water, reach out to a plumber for an accurate diagnosis and long-term solutions.

Leaks

Water heater leaks are telltale signs of underlying issues, such as overheating. When the temperature rises in the tank, the pressure builds up and causes leaks. If you experience frequent leaks, it may be excess heat causing tank failure or loose connections. It is advisable to address leaks quickly, ensuring optimal efficiency and safety all year round.

Age

While a water heater can run for over a decade without showing signs of damage, there will come a time when your system will struggle to perform optimally. Older systems are more susceptible to corrosion, buildup, and leaks, which eventually lead to overheating. If your system is near or exceeding the 10-year mark, early intervention when dealing with overheating is vital to avoid inefficiencies and safety hazards.

How to Prevent Your Water Heater from Overheating

As mentioned, overheating is a common problem that can cause system malfunctions and safety hazards. Fortunately, you can take several steps to keep your water heater in top shape. It all starts with regular maintenance and inspections by a reputable plumbing service in Anaheim, CA. This includes emptying and cleaning mineral buildup from the tank.

In addition, routine checks ensure that minor signs of deterioration do not worsen over time and cause further damage.
