What Is The Best Type of Fire Sprinkler System?

- Wet Pipe – This is the most common type and most buildings utilize this system. It holds water in the pipes behind the sprinkler head.
- Dry Pipe – This type is used in areas where the cold temperature can freeze the water in the pipes. Pressurized gas and water are held outside the pipes until the sprinkler heads are triggered.
- Deluge – Like in wet pipe fire sprinklers, water is stored in the pipes but the fire sprinkler heads are kept open. A fire alarm will activate the system and it needs to be manually closed to switch off the system. This type is normally used in warehouse bay entryways, high rise windows, and areas where fire could spread rapidly.
- Pre-action – This type is a combination of wet and dry pipe types. Water is not stored in the pipes. Yet, when a fire is detected, it quickly fills the pipes before the sprinkler heads open.
