Protecting our water quality is one of the most important challenges we face. Fortunately, understanding the health risks of cross-connection and backflow can help ensure a continued source of potable water.
WHAT IS BACKFLOW?
Backflow is undesirable reversal of flow of water or mixture of water with other liquids, gases or substances in the distribution pipes of potable water from any source.
WHEN DOES BACKFLOW OCCUR?
Backflow may be caused by conditions of gravity, vacuum or other pressure changes. There are two factors that contribute to reversal of flow in pipelines: back-siphonage and backpressure
WHAT ARE MY BACKFLOW PREVENTION OPTIONS?
Mechanical backflow prevention devices and assemblies can provide the best protection against cross-connection hazards.
Backflow prevention assemblies may be installed at the source of potential contamination or on the water service line itself.
