Guidance for Flushing Building Plumbing Systems after Prolonged Shutdown
Public water supplies are safe and unaffected by the SARS-CoV-2 virus that causes COVID-19. However, water quality within buildings that have been vacant or have seen little use during the pandemic restrictions may be impacted due the closure. To make sure stagnant water is fully removed before employees return to work, it’s important that building owners thoroughly flush their establishment’s plumbing systems before reopening.
To flush water systems in closed buildings, Hampton Roads utility directors advise owners and property managers to follow these steps:
Flush cold water first.
Flush hot water second.
Another best practice, especially for schools and daycare facilities, is the removal and thorough cleaning of end-point devices such as drinking fountain filters.
