Water Quality
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.
If your home runs on well water, NB Power, along with Health Canada, Public Health and the Department of Environment recommend that wells be tested twice a year for bacteria quality and every two years for chemical quality. As well, it’s recommended to get your wells re-tested if there is a change in the appearance, taste or smell of the water.
If you’re on municipal water, a change in appearance, taste or smell should be handled with care by having your water tested professionally and by contacting your local municipality or water treatment facility.
To help ensure your NB Power water heater is in tip-top shape, we recommend you flush your tank yearly. This can help minimize sediment and bacterial build-up in your tank.

My hot water is dirty. What should I do?
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, heating your water can make your water quality issues more noticeable, especially those related to mineral content and contamination. 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.
My hot water smells bad. What should I do?
Sometimes bacteria, sediment, minerals or natural gases may find their way into the plumbing and sometimes into the water heater in your home, which can cause the water to smell differently. The following are the most common smelly water problems:
If your water has a rotten egg or sulphur smell or taste, you may have an issue with your water chemistry. The rotten egg smell happens when sulphates from groundwater and micro-organisms in your water react, and create Hydrogen Sulphide (H2S) gas.
In some cases, the odour may be noticeable only when the water is first turned on or when hot water is run. Heat forces the gas into the air which may cause the odour to be more noticeable in a shower.
If the problem persists, we recommend you contact a water quality specialist to determine the correct course of action.
For a full listing of possible solutions, please contact your water quality specialist or visit the Department of Environment website.
If water smells oily it is possible that the water supply or plumbing has been contaminated with gasoline, oil or bacteria. This could mean there’s a health risk.
In rare cases, you may notice an oily smell with a new water heater. This is a reaction of the water chemistry with the new components of a water heater. This can happen with new appliances and should go away within a couple weeks with regular hot water use.
If the problem persists we recommend you contact a water quality specialist to determine the correct course of action.
If your water smells musty or like sewage, there could be iron, algae, bacteria or decaying organic matter in your plumbing and water supply. This could be a seasonal issue or a health risk.
During periods of limited use, water can become stagnant and produce these odours.
In some cases, the unpleasant smell comes from stagnant water or the presence of bacteria in a drain. If the smell is only in one room, then this may be the cause of the smell.
If the problem persists we recommend you contact a water quality specialist to determine the correct course of action.

The National Plumbing Code, CSA and the World Health Organization have set a mandate that water heaters used in Canada come factory set at 60°C (140°F) to reduce the risk of bacterial growth and potentially legionella in electric water heaters. Download our Legionella brochure to learn more.
