LIHUE — The Department of Water (DOW) reminds resort properties and large commercial facilities to conduct a flushing of their plumbing fixtures on property at least once a week and prior to reopening for business. The flushing protocol is also recommended to schools and businesses that have significantly reduced their water demand within their systems during COVID-19 related closures or extended property vacancies.
A significant decrease in water demand; which includes the discontinued use and maintenance of water fixtures within a building can cause stagnation; furthermore, existing sediment in pipes can be stirred up in the water upon returning to normal water use. The flushing process will help to prevent stagnation, clear out existing sediment and help to ensure chlorine residuals (which checks microbial growth) are maintained within their facilities.
Existing maintenance plans should also include the proper care of cooling and air conditioning systems and property’s hot water systems.
