How to Inspect Water Heater Tanks Course

in taking this course, posting required picture.
This electric heater is installed in a multi-story condo building, heater is installed on concrete blocks, no drain to outside, TPR venting to floor, and though not part of the water heater inspection, the MPOE service line, which has a water meter installed does not have any shut off. No way to turn water off without shutting down entire building!
