Who Performs The Test?

Individuals certified and  recognized by your city of residence for backflow prevention testing and repair must perform the tests.  Upon completion, the tester will submit the test report(s) to the Environmental Division for entry.

 

What is Backsiphonage?

The positive flow of water can be reversed when there is a sudden reduction in water pressure in the distribution system, such as during firefighting or when a water main breaks.  This can create a suction effect, drawing the non-potable substance into the potable water system.
