Abstract
A pop up roof sprinkler system includes a building having a roof, a fire retardant solution, a dispensing tube that has a distal portion extending outwardly from the roof, and a cap member. The cap member has a head portion and an insertion portion. The insertion portion is inserted into the dispensing tube such that the cap member is movable between an open position and a closed position. The open position is defined by the head portion being spaced from the dispensing tube to permit dispensation of the fire retardant solution through the dispensing tube.
