Which test is associated with dislodging foreign matter in the system?

• A. Cross-connection test
• B. Verifier's piping purge test
• C. Leak test
• D. Flow test

Answer: (B)

Purging the piping to remove debris is the key idea here. The verifier's piping purge test is specifically used to dislodge and flush out foreign matter from the system by forcing water through purge points, pushing debris out so the lines are clean before further testing or operation. This focuses on cleaning the interior rather than measuring performance or checking for backflow protection. Other tests have different purposes: cross-connection tests verify that backflow protection is functioning to prevent contaminant entry, leak tests check for water-tightness under pressure, and flow tests assess the system’s delivery of water at required rates. Purging directly targets removing debris, making it the best fit for dislodging foreign matter.
