Find a Certified Tester

To find a certified tester for a backflow prevention device, check the list of registered contractors.

  1. Backflow
  2. Cross-Connection
  3. Backsiphonage
  4. Backpressure

Backflow can be described as "a reversal of the normal direction of flow within a piping system" or as "the flow of water or other liquids, mixtures or substances into the distribution pipes of a potable water supply from any source other than the intended source of the potable water supply."

Potential

The potential for a backflow condition occurring in a water system is all too likely in many of our homes, factories and public buildings. The existence of improper plumbing connections presents cross-connections that may, under backflow conditions, permit the water to flow the wrong way within the piping.

Probability

The probability of backflow taking place at any given outlet may actually be very small. But in view of a large number of service connections, the multiple cross-connections at each service connection and the potential for cross-connections to be created, then the probability becomes very significant and must be dealt with in a positive manner.
