NB POWER- How To Flush Your Hot Water Tank - Jul. 08, 2013

Residents sometimes will see some discolouration in their water due to the fact that the hot water tank needs to be flushed.  This may not solve each concern but it is a place to start.


NB Power has produced a "how to" and it is as follows:




To help ensure that your NB Power residential water heater works at optimal performance, yearly tank flushing is recommended. Tank flushing can help minimize sediment accumulation. In order to carry out this task, please follow these steps:




  1. Using caution, turn off electricity to water heater.


  2. Close cold water supply to water heater using the shut off valve; see diagram.


  3. Attach one end of a garden hose to the drain valve located at the bottom of the water heater; see diagram. Direct the other end towards a drain to safely discard water from water heater.


  4. Open drain valve. Caution must be used as water coming out of the hose will be hot.


  5. Open the hot water tap located closest to the water heater. This will allow the water from the water heater to drain completely.


  6. Open the cold water supply to water heater using the shut off valve for 10-30 seconds, then shut the cold water supply off. This will stir up any remaining sediments in the bottom of the tank. Allow the tank to drain again. Repeat until the water runs clear from the hose.


  7. Close the drain valve and reopen the cold water supply allowing the tank to refill.


  8. Remove the hose from the drain valve.


  9. Once the water flows free of air from the opened hot water tap, you may close the tap as your water heater is now full.


  10. Turn the electricity back on to the water heater. It will take 3 to 4 hours to completely reheat your water
