Q: What is backflow?

A: Simply put, backflow is the reversal of the flow of water created by a difference in water pressures that causes water to flow back into the distribution pipes of a potable water supply.


Q: What is a cross-connection?

A: A cross-connection is any temporary, permanent, or potential connection between a public water system or consumer's potable (i.e., drinking) water system and any source or system containing non-potable water or other substances. For example, having an irrigation or drinking water well on the property, having access to reclaimed water, or leaving a garden hose in a pool. 


Q: What is a backflow prevention assembly?

 A: A backflow prevention assembly is a means or mechanism used to prevent backflow.


Q: Why do backflow prevention assemblies need to be tested?

 A: Mechanical backflow prevention assemblies have internal seals, springs, and moving parts that are subject to fouling, wear or fatigue.


Q: How often does the backflow prevention assembly need to be tested?

A: In order to ensure the proper operation of a backflow prevention assembly, it must be tested and certified upon installation and at least once a year thereafter by a certified backflow tester.


Q: How can I contact a certified backflow prevention assembly tester? 

A: View a list of Melbourne-area accredited companies.


Q: What type of document needs to be returned to the City of Melbourne as proof that testing of the backflow prevention assembly was completed?
