Water Service for Businesses
When water is left stagnant in your building's pipes, the water quality can change. If you are re-opening after weeks of inactivity, please take the following steps to ensure your water is safe to consume:
Flush Internal Pipes
- Run water through all outlets, such as faucets and showers, and flushing your toilets and urinals for 10 to 30 minutes.
- Outlets at the greatest distance from the service connection should be flushed the longest.
- Flush the cold-water lines first and then the hot water lines.
- Flushing process will vary depending on each plumbing system.
- Personnel doing this work should be advised to open outlets slowly to avoid splashing and the creation of aerosols.
- Flush all drinking water fountains, water coolers, bottle fillers and any other operable end point device. Remove and clean faucet aerators and replace drinking fountain filters.
- For ice makers, dispose of old ice and flush the water supply to the ice maker.
- Run water softeners through a regeneration cycle.
- Drain and refill hot water heaters set below 45°C (normal setting is 60°C).
- Remember all other water systems in a building, such as water reuse systems, decorative water features such as fountains, and landscape irrigation systems. Follow manufacturer recommendations for disinfecting all water systems after periods of non-use.
Check P-Traps (Drains)
- A dried-out or empty P-trap can cause sewer gas odours. An easy fix is to fill the P-trap with water again.
- Walk around your business with a pitcher of water and pour water down every drain you can find. Items that have had regular use (sink, toilets) probably have water in the P-trap already.
- Flush any unused toilets.
- Pour water down floor drains.
Personnel working to rehabilitate stagnant water systems will be at some risk and should be advised to take precautions. If plumbing issues continue, contact a licensed plumber for assistance.
