How to Prevent a Fire Sprinkler System From Freezing

A fire sprinkler system is one way to protect your home from a fire and allow more time for occupants to evacuate in the event of a fire. These sprinkler systems run along the ceiling and contain a heat sensor that will turn the sprinklers on when a certain temperature is reached. It is very important to properly maintain a fire sprinkler system, especially during cold winter months. When temperatures drop, sprinkler systems can freeze, which can cause the pipes to burst. Knowing how to prevent this will save you money while keeping your home protected.

• 1

  Contact a local heating repair company immediately if your furnace goes out during the winter. A fire sprinkler system must be installed in an area that remains 40 degrees or higher year-round to keep the pipes from freezing.

• 2

  Verify that all the pipes for the fire sprinkler system are properly insulated. This is extremely important for pipes that run outside the home or in a cold basement. If any insulation is missing or damaged, replace it with a new piece to prevent the pipes from freezing up. Keep the fire hydrants running to your sprinkler system free of snow and ice.

• 3

  Keep your home draft-free during periods of freezing temperatures. Drafts can cause the temperature inside the home to drop. Check all of your home's windows and doors for air leaks. Repair any damaged weatherstripping to keep the inside of your home warm.

• 4

  Repair or replace any loose or damaged pipe hangers, to prevent damage to the fire sprinkler system. If insulation has to be removed to fix a hanger, replace the insulation properly around the pipe when you're done.

• 5

  Call your fire sprinkler service company to schedule regular maintenance on the sprinkler system. The company will check the sensors, valves and pipes to make sure the system is working properly. Never try to make any repairs to the pipes, valves, or sensors on your own.
