Contact an EMD registered tester from the Certified Backflow Prevention Assembly Tester list and have them test all of the backflow assemblies listed on the notice.
Once they have tested your assemblies, the tester will put a blue colored test tag on your backflow assemblies. This tag shows you, and EMD, that your assemblies passed the field test.
When finished, the tester will electronically submit the test data to EMD. Ask the tester to send you a copy of the electronic test report; it includes the date EMD received the compliance information.
Ultimately, it is the responsibility of the owner and/or operator for making sure EMD receives the test reports within 20 days of the field test.
