A study by the National Fire Protection Association (NFPA) found that water heaters caused over 6,000 home fires, 80 fatalities, and over 300 serious injuries. In addition, they were responsible for over 7% of home-related fatalities. To ensure that your water heater works optimally and doesn't cause harm to your household, you need to keep it in good working order. Below are five common signs that you need water heater repair.

Water That is Too Hot

According to the Consumer Product Safety Commission (CPSC), you should set your water heater to no more than 120 degrees Fahrenheit. Temperatures higher than this will cause scalding and burns. Temperatures over 140 degrees Fahrenheit will cause third-degree burns in minutes. If your water is starting to feel too hot, your thermostat is broken and you need to get it repaired

Reduced Water Flow

Sediment or scale build-up can block your water heater and cause reduced water flow. If you experience a sudden reduction in your shower water, it may be time to call in a heating repair service.

Strange Noises

Crackling, popping, sputtering, and boiling sounds from your water heater come from sediment build-up. A malfunctioning heating element can also cause bubbling sounds. You can fix problems from excess sediment by yourself. However, call a heater repair service if you notice boiling sounds as this means that your heating element has malfunctioned.

Smelly or Discolored Water

Rust-colored water and the smell of rotten eggs are a sign that bacteria has entered your water heater. Brown water results from a broken anode rod. You can determine whether the problem is caused by your water heater or water source by turning on the hot and cold water faucets. Cold brown water means that your water source is the culprit while hot brown water means that your anode rod is broken.

Water heater problems can result in scalding temperatures, insufficient water, and stinky and slimy water. Looking for the tell-tale signs of problems with your water heater will help you solve problems before they cause permanent damage.
