<p>A fluid handling system is operative to deliver water based fluid through a plurality of plastic pipes and fittings to a plurality of fire suppression sprinkler heads (12). The fluid handling system includes a plurality of fittings (14, 16, 18, 20, 22). The fittings are joined in the system in cemented relation. The fittings and pipes are comprised of chlorinated polyvinyl chloride (CPVC) that is suitable for fire suppression applications. The failure of an installer to connect one or more fittings in the system in cemented relation is detectable through use of an apparatus (24). The apparatus operates to detect uncemented connections while avoiding pressurizing the system above a limit.</p> |
