How frequently must foam bladder integrity tests be conducted?

Explanation:
Foam bladder integrity is checked annually to ensure the bladder that separates the foam concentrate from the pressurized side remains intact. Regular annual testing confirms there are no leaks, ruptures, or material degradation that could prevent proper foam delivery or contaminate the system. This interval matches standard maintenance practices for foam systems, with more frequent testing only if the manufacturer or local codes require it.
