Methods for eradicating biofilms from plumbing systems

Abstract

Disclosed are advantageous systems and methods for treating building water systems, especially the interior surfaces of premise plumbing, to remove biofilm and inactivate biofilm-associated pathogens, including protozoa, using disinfectant formulations at concentrations at in excess of those used for drinking water treatment, and further, in co-applying complexing agents to mitigate corrosion of the materials treated; and using these in conjunction with off-gas containment devices that allow flushing of taps without the liberation of toxic fumes.
