Is your facility preparing to reopen? Building managers should be sure to flush the pipes in order to ensure optimal water quality.
When buildings and business are closed for an extended period of time (e.g. one week or more) a thorough flushing process is needed to move out water that may have been sitting stagnant inside the building's plumbing. Stagnant water, for even as little as two days, can lead to low or undetectable levels of disinfectant, such as chlorine. This water can become unsafe to drink or otherwise use for personal or commercial purposes. Proper flushing can restore chlorine levels and ensure water quality for the premises. Building owners, building managers, and businesses should take steps to flush the building’s plumbing before reopening.
Ensure that your water system is safe to use after a prolonged shutdown by conducting a flush of your commercial or residential property’s internal plumbing. Flushing instructions will vary depending on the size and complexity of the structure and its plumbing. Owners of commercial and residential properties are encouraged to follow the guidance below when reoccupying a building.
