Piped Services- Flushing Requirement

Government of Nunavut Public Health recommends that residents on piped services (utilidor) clean and flush their residential water system.

This applies to residents and businesses on piped services (utilidor.) These resi-dents are asked to ensure they are flushing their home systems between October 28 and October 30th. Flushing will occur by neighbourhood:

October 28th and 29th (Thursday and Friday): Road To Nowhere, Plat-eau/Lower Plateau and Federal Road.
October 30th and 31st (Saturday and Sunday): Happy Valley, Green Row, Lower Iqaluit and Lower Base.

Please use the following guide, provided by the Government of Nunavut, to flush your system:

1. Flushing cold water taps

o Isolate any point-of-entry treatment unit (e.g. filter, water softener), prior to flushing.
o If there is a point-of use filter, remove the filter cartridge and replace with a new one after flushing (e.g., carbon pre-filter on a reverse os-mosis system).
o Start by running the cold-water faucet closest to the entry to the house. Then sequentially open remaining cold-water taps moving pro-gressively away from entry. Run the water for a total of 20 minutes.
o Remove and clean aerators where possible. If a bathtub has a spout and showerhead, direct the flow through the spout.
o Flush each toilet once.
o Flush all outdoor taps for 10 minutes.

o After flushing all taps, direct the flow from the bathtub spout to the showerhead if applicable.


2. Flushing hot water taps and water heater (tank or on-demand)

o Run the hot water taps, beginning with the one closest to the hot water heater and proceed to open all taps.
o If a bathtub has a spout and showerhead, direct through the shower-head first.
o Allow the water to run until cool to warm. For approximately 75-minutes (for 80-gallon hot water tanks, or approximately 1 minute per gallon) for on-demand hot water heaters, flush for at least 10 minutes.
o Turn off faucets.
o After flushing all taps flush through bathtub spout for 2 minutes.


3. Cleaning appliances (to be completed after premise plumbing is flushed)

o Run empty dishwasher and washing machine with detergent for one cycle.
o Replace all water filters and regenerate or replace treatment media (e.g., whole-house filter media, refrigerator filter cartridge, ion ex-change resin, water jug filter, etc.) after the premise flushing is com-pleted. Reverse osmosis units generally contain a carbon pre-filter which should be replaced.
o Water softeners should be regenerated per manufacturer’s instruc-tions
o Run fridge water dispenser for 5 minutes.
o Empty ice maker bin; run ice maker and discard 2 additional batches of ice.
o Kettles, coffee makers and other small appliances that use water should be cleaned.
▪ Accessible parts such as water reservoirs hand washed with soap and water and rinsed thoroughly.

▪ Inaccessible areas flushed with 2 or more volumes of water through the unit.
o Water jug filters can be cleaned.
▪ Hand wash reservoir and filter housing and rinsed thoroughly.
▪ Replace the filter.
o Humidifiers can be cleaned (Mayo Clinic, 2021).
▪ Wash the tank with dish soap and clean water and rinse thor-oughly.
▪ Change the filter or wick as per manufacturer’s directions.

Flushing pipes with fresh water will help remove remaining hydrocarbons from your plumbing system.
