A medium-sized water heater carries around 80 gallons of water. Imagine how much damage would result if the water heater released all of that water into your home. If you notice any of the following signs of a deteriorating water heater, contact a water heater technician right away:

  • Dripping, leaking, or pooling water
  • Rust and corrosion
  • Burn marks near the bottom of the water heater
  • Flame color is any other color than blue (the flame under your tank should be blue)
  • Popping, rattling, and clinking noises

Don’t wait for your water heater to fail completely. Contact a professional plumber to check your water heater’s anode rod, drain the water heater, and inspect the entire system for optimum safety and efficiency. Depending on your water heater, you should flush it every 1-3 years.
