My lady just called and advised me the fire sprinklers in her home let go due to a ruptured pipe in the center portion of the structure. The damage took place between level two and three when a plastic pipe that is about ten years old fractured. Freeze doesn't appear to be the issue, the home has been heated throughout the winter. The repair is going to be massive and require removing drywall ceilings, drywall, insulation, flooring, you name it. The system was installed by a licensed contractor in 1996 and signed off by the fire marshal.
This is the third incident of this nature I have heard of in the last two weeks. The new county courthouse was damaged by a similar break according to the Victorville paper.
Question: Are the new systems equipped with fail safe devices? Did they abandon the use of plastic water pipes like they did in the modular home business? Retrofitting a new system is going to require complete demolition of all ceiling and wall surfaces. I know we have some sprinkler fitters in the forum group so I would appreciate hearing from them.
