Water Supply & DistributionQuestion 16 of 360
What is the fundamental purpose of cross-connection control in a potable water system?
a.To increase available flow at fixtures
b.To reduce pipe friction losses
c.To lower the water heater temperature
d.To prevent contaminants or pollutants from entering the potable water supply through backflow
Explanation
Cross-connection control exists to prevent backflow of contaminants or pollutants into the potable supply. Increasing flow, reducing friction, and lowering heater temperature are unrelated to the protective intent of these provisions.
