Fire Sprinkler Freeze Protection FAQs
How do I protect my fire sprinkler system from freezing?
Several measures exist for fire sprinkler freeze protection, including heat tracing, proper insulation, and the usage of UL listed antifreeze.

Can fire sprinkler systems freeze?
Just like plumbing and HVAC, fire sprinkler systems are subject to freezing. Typically, property owners do not know there is a problem until temperatures rise from above freezing levels. This is because ice will plug up any breaks in the pipe. It is only once the ice melts that signs of leaking become apparent.
Will sprinkler pipes freeze at 32 degrees?
Like anything else that contains water, fire sprinkler systems are subject to freezing at 32 degrees Fahrenheit. Luckily measures such as heat tracing and antifreeze exist to prevent this.
