ABSTRACT:
A flooding prevention device and a breakage prevention device for use with pressurized fluid systems are disclosed. The flooding prevention device includes a pipe with an interior passageway and a stopper located in the passageway, the stopper being adapted to seal the pipe whenever an accessory attached to the pipe is broken, thereby preventing fluid loss from the pressurized fluid system. The breakage prevention device includes a first pipe and a second pipe slidable within the first pipe, the sliding action accommodating pressure on or movement of components of the fluid system, thereby avoiding component breakage.
