Most water quality issues can be resolved by customers flushing their service line. In some businesses or apartment buildings, an outside spigot may not be available. In this case, follow the inside flushing procedure.
Outside flushing procedure
- Locate the outside spigot/faucet closest to the water meter.
- Run water with the faucet completely open for 10 to 15 minutes.
A hose may be attached to redirect the water to avoid waste. However, make sure you allow the largest amount of water to flow. Remove attachments like nozzles or sprinklers to allow a higher water flow. - Wait 30 minutes to an hour without using any water, if possible, allowing water in the main line to settle.
- Check water for clarity.
- If needed, flush for another 10 to 15 minutes.
In most cases, water will clear on the first or second flushing. However, a third flushing may be required especially when the clarity improves with each flushing - After water has cleared on the outside spigot, flush from the inside lines (see below).
Important tip
Avoid using hot water until cold water runs clear. The water heater may need to be flushed as well, refer to the manufacturer’s manual for instructions.
Inside flushing procedure
- Use a faucet on the lowest level located as close to the water meter as possible.
- Remove aerator (screen) from faucet (optional).
- Run the cold water for 3 to 5 minutes, or until the water runs clear.
- Move to the next faucet and repeat the procedure until all the faucets have been flushed (including the tub and shower).
