Question: Is it legal for a Backflow Tester to conduct Customer Service Inspections (Cross Connection Surveys) if the Water Purveyor approves?
Water Purveyors occasionally ask a BPAT (Backflow Prevention Assembly Tester) to locate and test all the backflow preventers within a facility because the purveyor does not have records of all assemblies. Soo - the BPAT does what the water purveyor asks and goes through the facility and test all the backflow preventers they see.
The tester misses one! The following year or so a contamination event occurs through the assembly missed by the tester. The tester was told by the purveyor to: ”locate and test all assemblies”! Who do you think will be held responsible and liable in this situation? The purveyor will blame the Tester.
