A. Approve the plans because most sprinklers receive
adequate pressure
B. Require system redesign or water supply improvements
before approval
C. Ignore the deficiency if a larger pipe size is shown
elsewhere
D. Approve with a verbal correction request
Answer: B
Rationale: Hydraulic calculations must demonstrate
adequate pressure and flow at the design point. Deficiencies
require correction before approval.
,2.
An inspector discovers installed sprinklers differ from those
