Why is my water heater making a popping sound?

Your water heater tends to be one of the most forgotten appliances in your home. This is because they are often located out of sight, therefore, out of mind. Because we forget about them, they are often suffering the consequences of little or no maintenance over the years. Typically, by the time that it begins making noise, it may even be too late.

Sound or Symptom: Water Heater is making a popping or rumbling noise. Cause: Sediment or Scale from Hard Water Solution: In some cases, the water heater may be drained and/or flushed to remove the scale or sediment. However, if this is not performed regularly, the tank can quickly deteriorate and eventually leak. Important Information: Did you know that scale forms in the tank within the first eight-hours of operation? This is because the burner or heating element heats the water, which is what causes the scale or sediment to separate and fall to the bottom of the tank. Eventually, the scale will adhere to the base of the tank, which is what causes corrosion and over-heating of the tank. Ultimately, this leads to tank failure.

How do I perform maintenance on my Water Heater? If you're a DIY Professional, there's many different versions out there on how to properly drain your water heater. The following steps should be followed to ensure your safety when draining your hot water tank.

  1. Turn Off the Water Heater - If you have a gas water heater, place the control valve in the "Pilot" mode. If you have an electric water heater, turn off the circuit breaker.

  2. Connect a Garden Hose to the drain valve and put the hose to a safe location to drain the hot water and sediment from the tank.

  3. Open the hot water drain valve slowly, until water is flowing thru the hose.

  4. Open the hot water drain valve slowly until water is flowing from the hose.

  5. Close the cold water feed valve to the water heater.

  6. Open a hot water spigot or tub valve inside the home.

  7. Once the water has drained, open the cold water inlet again (slowly). Wait 2-3 minutes before closing the cold water supply and draining again.

  8. Repeat steps 4, 5 and 6 until the Water Heater is free of sediment.

  9. Close the drain valve.

  10. Slowly open the cold-water valve to the water heater to begin filling.

Once you have completed all of the steps above and you are ready to get your hot water going again, follow the manufacturer's instructions on the front of the water heater for lighting instructions - or "energizing" instructions if it is an electric water heater.

Important Note: We highly recommend that you install a brass hose-bibb cap on the drain valve to prevent accidental leakage from the tank. Ensure that the gasket to the cap is seated properly - and never over-tighten the cap.
