  • Dose static tank water to 5 ppm available chlorine and leave for 5 minutes to drain off
  • Using a suitable sanitizing solution such as 200 ppm solution mixed with neutral detergent, thoroughly clean the tank and rinse out
  • Place sufficient tablets in the tank and does to 60 ppm, fill the tank with fresh water and leave overnight. Check for a chlorine residual of at least 50ppm before neutralizing, drain off and resume use

For all new water pipe installations, dosing the system to 50 ppm available chlorine for a minimum of 30 minutes before checking for chlorine residual is recommended.
