What is backsiphonage?
Backsiphonage is backflow caused by a negative pressure (i.e., a vacuum or partial vacuum) in a public water system or consumer’s potable water system.The effect is similar to drinking water through a straw.Backsiphonage can occur when there is a stoppage of water supply due to nearby fire fighting, a break in a watermain, etc.
When there is a sudden reduction in water pressure in the public drinking water distribution system, such as during fire fighting or when a water main breaks, water flow can potentially be reversed. This could create a suction effect, possibly drawing contaminated water into the drinking water system.
