Wet vs. Dry Fire Sprinkler System

One of the most important ways to make sure that your facility is protected is to have the proper sprinkler system that is designed to meet the needs of your application. Two common sprinkler systems that are installed in properties are wet pipe and dry pipe sprinkler systems.

Wet Pipe Sprinklers

Wet pipe sprinkler systems are the most common form of fire sprinkler. This is the traditional type of fire sprinkler where the sprinkler pipes are filled with pressurized water that will immediately discharge when a fire occurs.



Dry Pipe Sprinklers

Dry pipe sprinkler systems are filled with pressurized air or nitrogen instead of water to prevent frozen and burst sprinkler pipes in areas with colder temperatures. The pressurized air in the sprinkler pipes prevents water from entering the pipes. When a fire is detected, the air pressure in the pipes is reduced and a valve opens to allow water to flow into the sprinkler pipes and extinguish the fire.


  • Will not freeze in cold temperatures
  • Can be installed in addition to a wet system to protect colder environments


  • More difficult to maintain
  • More expensive to install
  • Slightly longer response time during a fire
