In the Field · Part 4
The Field: Method, Code, and Cases
27 lessons
One diagnostic method applied to every call a new C-36 gets: permits, the daily-use code, gas, water heaters, sewer and drain, leaks, pressure, sewer gas, treatment, fixtures, materials, commercial basics, Cal/OSHA, lead and asbestos, and the cases where the method decided the outcome.
