Who can test a backflow prevention assembly?
Domestic and irrigation service backflow assemblies may be tested by a plumber registered with BSI, who holds a current certification from an accredited institution (i.e.: TREEO, American Society of Sanitary Engineers). Fire service backflow assemblies must be tested by a licensed fire inspection company which is also certified for backflow testing.
