Frozen fire protection systems result in fire losses due to crippled detection or extinguishing systems and extensive water damage…
As temperatures drop this winter, fire sprinkler systems become vulnerable to freeze-ups. When water freezes inside a sprinkler pipe, it creates an obstruction that can render the sprinkler system useless in the event of a fire. As the ice expands, it increases the internal water pressure in the pipe, which causes the pipe to burst.
