What is Backpressure?

Backpressure is created when the pressure in a non-potable system, such as in a recirculation system containing soap, acid, antifreeze, or in a boiler system exceeds that in the potable water system that provides the make-up water to the system.  This pressure can force the potable water to reverse its direction of flow through the cross connection.  Non-potable substances can then enter the potable water system.

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.
