Answer

Brief Explanations:

For the first question, water - supply, waste - disposal, drain and vent piping are common inspection items for meeting standards, while water - heater chimneys are not among the typical ones for general standards inspection. For the second question, galvanized steel pipes often fail first at threaded connections due to stress concentration and potential for corrosion at the threads.

Answer:

First question: chimneys for water heaters Second question: threaded connections
