What are you testing? Are you Testing the Pressure?
We are testing the Backflow Prevention Assembly to determine and document whether it is functioning as it should. This is a Pass or Fail Test. If the Backflow Prevention Assembly Fails, it is nothing personal. We are required by the State and local authorities to Inspect and Document what we find.
There are several types of Backflow Prevention Assemblies, each with different testing instructions. The testing is conducted with differential pressure gauges! A visual inspection is no indication if a Backflow Prevention Assembly is working or not.
Following USC Testing Procedures a Backflow Test cannot occur with out briefly interrupting water service. If there are no complications, Most inspections can be completed with in 20 Minutes.
