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

A: A: The certified tester will complete a “Test and Maintenance Report" form documenting the results of the test. Please e-mail Michael.Demartino@mlbfl.org to request a form. The completed form must be uploaded to The Compliance Engine. The City of Melbourne will no longer be accepting these documents via email or fax. Please contact Compliance Engine directly at 630-413-9511 with any questions or concerns you may have regarding this process. Testers and contractors can find additional resources and helpful guides at https://supportitm.thecomplianceengine.com/
