Boil Water Advisory – Appliance FAQ

Key Message:

Once the boil water advisory is lifted, residents will be required to flush their internal plumbing lines by turning on all taps for at least 5 minutes (10 minutes if you live in an apartment building).

All appliances with a water connection should be flushed thoroughly ­– residents should contact their appliance manufacturer(s) for specific flushing and disinfection directions once the boil water advisory has been lifted.  

FAQs:

Will elevated levels of chlorine have an impact on my plumbing system (i.e. fridge water/icemaker)?

The disinfection process should not impact your internal plumbing or appliances. However, residents will be required to flush their internal plumbing once the boil water advisory is lifted. Fridges with a water system and icemakers should not be used until the boil water advisory is lifted.

All appliances with a water connection should also be flushed thoroughly ­– residents should contact the appliance manufacturer for specific flushing and disinfection directions and follow through with those instructions once the boil water advisory has been lifted. 

Do I have to flush water following lifting of the boil water advisory?

The disinfection process currently underway should not impact your internal plumbing or appliances. However, residents will be required to flush their internal plumbing once the boil water advisory is lifted. 

Do I have to disinfect my appliance?

All appliances with a water connection should be flushed thoroughly once the boil water advisory has been lifted. Since all appliances vary, and each make or model will have different instructions, residents should contact the appliance manufacturer for specific flushing and/or disinfection directions once the boil water advisory has been lifted. The manufacturer should be able to advise on whether disinfection is required, or if simply flushing the appliance would be fine.

These appliances include, but are not limited to, dishwashers, fridges with water connection and/or with automatic ice makers, hot water tanks, water softeners, and washing machines.

How do I flush/disinfect my appliance?

Every appliance, and the process to disinfect or flush it, is unique. Therefore, residents should contact the appliance manufacturer for specific flushing and/or disinfection directions once the boil water advisory has been lifted.  The manufacturer should advise whether disinfection is required, or if simply flushing the appliance would be fine. 

What should I tell the manufacturer when I call to get the best advice?

Residents should contact their appliance manufacturer(s) for specific flushing and disinfection directions once the boil water advisory has been lifted.  These are the points you should advise your manufacturer on that call to get the most accurate instructions on flushing/disinfecting your appliance:

  • The Alberta Health Services boil water order was issued in response to infiltration of river water at the Water Treatment Plant. The introduction of untreated water into the distribution system automatically triggers a boil water order as a precaution against the potential introduction of pathogens to the drinking water distribution system.
  • During the flood, turbidity levels increased in various reaches of the distribution system, leading to some residents in the region experiencing discoloured water and sediment.
  • Work is underway to clean, disinfect, and test both the water treatment plant and the distribution system. In time, the plant and the entire water distribution system, including reservoirs and 375 kilometers of pipe will be flushed, disinfected, and tested to restore potable water.
  • The RMWB has advised that all appliances with a water connection should also be flushed thoroughly and that residents should contact their appliance manufacturer(s) for specific flushing and disinfection directions once the boil water advisory has been lifted.
