What Is Back-Siphonage?

Back-siphonage is backflow caused by negative pressure (i.e. vacuum or partial vacuum) in a public water system or customer’s potable water system.  The effect is similar to drinking water through a straw.  Back-siphonage can occur when there is a stoppage of water supply due to nearby firefighting, a break in a water main, etc.
