Where is the main control valve for an automatic sprinkler system located? Locate the main shutoff valve on your irrigation system. It is between the main
What Would Set Off A Sprinkler System? Fire sprinklers work because high heat triggers the sprinkler system. When a blaze ignites, the air directly above it heats rapidly. This hot air rises and spreads along the ceiling. When the air is hot enough and reaches a sprinkler head, it triggers a chain reaction. What do
How Often Do Sprinklers Need To Be Tested? Every 10 Years. Dry sprinkler systems should be tested and/or replaced after ten years. Fast-response sprinklers should be tested after 20 years and at 10-year intervals after that, and standard sprinklers should be tested after 50 years and then at subsequent 10-year intervals. How often should sprinklers
What Causes Apartment Sprinklers To Go Off? Most sprinkler heads feature a glass bulb filled with a glycerin-based liquid.
