Lacey Advises Businesses to Flush Water Pipes Prior to Reopening

Submitted by City of Lacey

The City of Lacey advises businesses to flush the pipes and water fixtures in their building prior to reopening, if it has been vacant for more than 30 days without any water usage.

With little or no water running through water pipes and fixtures for an extended period of time, stagnant water conditions can result in discolored water, odors, and lower chlorine levels. Higher concentrations of lead and copper can also develop, depending on the age, condition, and type of plumbing and fixtures in the building.

Fresh water should be drawn into the building’s water system and stagnant water flushed out, before it is used for drinking. All the cold-water faucets should be flushed for a minimum of 20 minutes, or until the water is noticeably colder than when the flushing process began.

To-do checklist:

  • Flush hot and cold water through all points of use (showers, sink faucets, etc.).
  • Check ice machines for old ice and clean per manufacturer’s instructions.
  • Determine if your water heater manufacturer recommends draining the water heater after prolonged period of non-use.
  • Clean all decorative water features, such as fountains, to remove films that can harbor bacteria or harmful growth.
  • Ensure safety equipment including fire sprinkler systems, eyewash stations, and safety showers are clean and well maintained.

If the water is discolored or has an odor once flushing is completed, please contact City of Lacey Operations at 360-491-5644.
