As our economy begins to open back up, the U.S. Centers for Disease
Control and Prevention (CDC) and California State Water Resources
Control Board (State Water Board) have issued guidance for reopening
facilities closed for an extended period during the COVID-19 pandemic.
Taking precautionary steps will ensure the safety of building water
systems and devices.
Businesses that are reopening after an extended shutdown should consider
flushing plumbing fixtures of stagnant water before resuming normal
operations.
Stagnant or standing water has the potential to cause conditions that
increase the risk for growth and spread of Legionella and other
biofilm-associated bacteria. Flushing involves opening taps and letting
hot and cold water run through all points of use (such as faucets and
showerheads) for a sufficient amount of time. The goal is to replace
stagnant water in interior pipes and/or outlets with fresh water.
