From the initial list of water audit questions in the Green Plumbers Reference Manual, what is the rough proportion, respectively, of those that are directly related to usage behavior vs. those that are related to billing, repairs, and the presence/performance of certain appliances and fixtures?
Explanation
Answer: A - The rough proportion of the 22 initial water audit questions that are usage behavior-related vs. related to billing, repairs, and the appliances/fixtures themselves is approximately 1:2 (7 to 15). Usage-related questions pertain to subjects such as shower length, frequency of garbage disposer and washing machine use, and frequency of backwashing pool filter. Other questions pertain to subjects such as water bill changes, observed leaks, added appliances, and irrigation systems.
