What is backsiphonage?
Backsiphonage is a condition created by a loss of pressure in the water distribution system. Water main breaks and firefighting are 2 examples where if the pressure lost is significant, water flow can potentially reverse. This pressure loss can create a suction effect, possibly leading to contaminated water being drawn into the public water system.
