Flush water lines first before re-opening businesses closed during COVID-19 shutdowns

Post Date:04/28/2020 2:21 PM

The Utilities Department recommends flushing the water lines before re-opening any business that has been closed long-term during the COVID-19 pandemic. It’s important to flush the lines of stagnant water in the plumbing system.

Utilities recommends putting together a comprehensive flushing plan as part of any re-opening schedule. Flush hot water lines at every tap for several minutes, then flush the cold water lines at every tap for several minutes. Consider draining water heaters, then flushing the lines once the heating tank has re-filled.

Restaurants, in particular, should flush all kitchen lines, including sinks, dishwashers, ice makers and similar appliances. Restaurants should also consider emptying and re-filling ice makers and similar appliances that pull water directly from water taps.

Best practices may vary for each type of establishment, including the length of time lines need to be flushed. Contact a licensed plumber if you have questions.
