Requirements for backflow assemblies are determined by the degree of hazard present at a customer’s premise. For example, customers with in-ground irrigation systems or auxiliary sources of water must have a backflow assembly. When reclaimed, well or pond water is present, backflow assemblies are required on the JEA drinking water line to prevent entry of water from those auxiliary systems into the public drinking water supply. Likewise, in-ground irrigation systems utilizing a JEA irrigation or domestic water service are required to have backflow protection on the water supply line.
This happens in two ways:
JEA and the City of Jacksonville Building Inspection Division require
backflow assemblies to be installed by certain customers on their drinking water
supply lines. Backflow assemblies prevent non-potable water from entering the
public water supply.
Assemblies must be tested annually by a certified
backflow tester to make sure they function properly.
