Question

which of the following is the inspector required to do?
○ test vacuum breakers
○ operate temperature/pressure relief valves on a water heater
○ observe private waste disposal systems
○ operate the isolating valve at the toilet
○ operate the spray feature of the bidet

question 11
vulnerable spots in shower and bathtub enclosures include all of the following except
○ faucet penetrations
○ the top of the tile where it joins the conventional wall finish
○ soap dishes
○ grab bars
○ windows

Explanation:

For the first question, inspectors typically observe private waste - disposal systems as part of their duties. They do not usually operate specific fixtures like water - heater valves, toilet isolating valves, or bidet spray features, and testing vacuum breakers is not a common general inspection requirement. For the second question, faucet penetrations, the top of tiles where they meet the wall finish, soap dishes, and grab bars can be vulnerable spots in shower and bathtub enclosures due to potential for water leakage or structural issues, while windows are not typically considered vulnerable spots in the same context.

Answer:

1. C. observe private waste disposal systems
2. E. windows
