What does a backsiphonage condition usually cause?

• A. Increased
• B. No change
• C. Reduced
• D. Fluctuating

Answer: (C)

Backsiphonage happens when the pressure in the water distribution system drops below the pressure in a customer’s service line. That pressure drop creates a siphon that draws water from the customer’s piping back into the distribution system. Because the system is experiencing a lower pressure, the overall effect is a reduction in available pressure in the distribution system, which is why the usual outcome is reduced pressure.
