installed between the upstream shutoff valve and the inlet of  

the backflow preventer.

It’s important that this device be tested periodically in compli-

ance with local codes, but at least once per year or more as 

service conditions warrant. If installed on a fire sprinkler system, 

all mechanical checks, such as alarm checks and backflow  

preventers, should be flow tested and inspected internally in  

accordance with NFPA 13 and NFPA 25.
