  • Regularly testing your water and logging results
  • Interpreting results of in – house tests and making appropriate corrections to your treatment program
  • Establishing parameters for the use of chemicals and methods for the introduction/removal for the system
  • Ensuring that equipment is fed, bled and blown-down
  • Establishing chemical inventory and reorder points
