Question 1 of 12
Single answer
Why does a building that reuses water need a dual (two-pipe) system rather than a single network?
A
Because two pipes carry water faster than one
B
Because it now carries two grades of water - potable and non-potable - that must be delivered to different outlets and kept absolutely separate
C
Because building codes require two pipes in every building regardless of reuse
D
Because a second pipe provides backup if the first one leaks
