When the water has under ten ppm of chlorine, repeat complete technique. The slime, scale, and odor-making bacteria will communicate with the chlorine and reduce the amount of chlorine residual from the piping.
It permits diluted water with various residual levels of chlorine to flush throughout the program. It also can produce extremely higher levels of corrosive chlorine (over 500 ppm) which might harm fixtures and corrode copper and chrome steel.
Caution: Should the shock-chlorination treatment is staying performed on an old pipeline, or one which has amassed scale or buildup, the process can loosen up scale, iron deposits along with other resources while in the piping, which often can clog fixtures, appliances and valves in the piping technique, producing lots of issues.
