How do I know if my FSS has Trapped Air at the highest points which could be leading to pinholes and corrosion?

My AHJ is requesting we get a 5 Year Assessment for our FSS.  I can not risk having a sprinkler system drained with the potential of flooding and contamination.  Is there an option supported by NFPA?
