>From old time experience there may be obstructions at the dry inspector's test valve or other that is obstructing the flow of air. From insurance inspector days anything over 3 minutes needs further investigation. I would have called 15 minutes a failure in the 60's and 70's.

How long is too long of a time for a dry valve to trip before it is considered a deficiency? 25 does not specify but 15 min seams too long. Don't have the previous report to compare it to.
