Water Quality


Did you know that water quality can impact the performance of the water heater?

Understanding your home’s water quality is an important way for you and your family to continue enjoying the benefits of your NB Power water heater safely. NB Power water heaters do not cause water quality issues, however water quality can have an impact on water heater performance.

Bad smells

Sometimes bacteria, sediment, minerals or natural gases find their way into the plumbing and the water heater, which can cause the water to smell differently. The following are the most common smelly water problems:

Rotten egg smell
Oily Smell
Methane, Musty, Fishy, Sewage


Dirty/discoloured water

If your tap or toilet water starts to turn a rust colour (yellow, orange, brown or red,) your water may be high in iron. Water with high iron can be filtered to help ease this problem. If you are on municipal water, you can contact your local municipality for assistance.

If you’re experiencing water quality issues with well water, we recommend you contact the New Brunswick Department of Environment to book a metal scan water test to determine the proper course of action.

Helpful tips

  • Test twice a year (wells)
    If your home runs on well water, it’s recommended it be tested twice a year for bacteria quality and every two years for chemical quality. 
  • Changes in appearance, taste or smell
    If you’re on municipal water and notice a change in appearance, taste or smell, please contact your local municipality or water treatment facility. If you are on a well, please contact a professional water tester.
  • Flush the tank yearly
    This can help minimize sediment and bacterial build-up in your tank. Watch this video to learn how easy it is to flush the water heater. 
  • Never adjust the temperature
    Reducing the temperature of your NB Power water heater below 60°C (140°F) can create a safety risk to you and your family, creating the possibility of bacterial outbreaks such as Legionella. It's factory set to 60°C to keep your family safe.  If you think your hot water is above or below this temperature, please call us at 1 800 663-6272
