As the cold winter starts to set in, it’s critical to start planning to winterize your fire sprinkler system. Your sprinkler system is at risk of freezing if exposed to cold temperatures just like your plumbing system, even when filled with antifreeze solution. Fortunately, there are ways to protect your sprinkler system from freezing and keep your fire protection at its peak level. Just follow these tips to winterize your sprinkler system.
The type of antifreeze to use in your system will depend on what your sprinkler system is made out of. If the system is made of CPVC and connected to a potable water supply, you should use an antifreeze solution made with glycerine as opposed to one made of glycol. Using antifreeze made with glycol creates an environment that can damage CPVC pipes. If the system is made out of a material other than CPVC, you can use a propylene glycol-based antifreeze solution to help winterize your sprinkler system. Backflow preventers may also be required if your sprinkler system is connected to a potable water supply.
Meeting Installation Requirements
In order for a fire sprinkler system to function properly, it needs to meet specific installation requirements that depend primarily on site conditions and construction. Glycerine is heavier and thus might settle into lower pipes if the piping isn’t designed properly, leaving higher pipes at risk of freezing. Special piping arrangements can be made to alleviate this problem.
Sprinkler systems also need to be tested through the freezing season to ensure that the levels of antifreeze are sufficient for proper protection. Antifreeze tests include emptying the entire system into containers and adding concentrated liquid antifreeze as required before putting the solution back into the system. The NFPA recommends drawing a sample of the solution two or three times during the winter for testing. Doing this will help ensure that your sprinkler system will survive the cold winter and provide you with the same level of fire protection during the cold as you do in the warmer months.
