Wet Pipe

A sprinkler system in which all piping and sprinkler heads, at all times, are filled with water under pressure; the system discharges immediately when a sprinkler head operates, and the water continues to flow until the system is shut off. By a wide margin, wet pipe sprinkler systems are installed more often than all other types of fire sprinkler systems. They also are the most reliable, because they are simple, with the only operating components being the automatic sprinklers and (commonly, but not always) the automatic alarm check valve. An automatic water supply provides water under pressure to the system piping.

Operation - When an automatic sprinkler is exposed for a sufficient time to a temperature at or above the temperature rating, the heat sensitive element (glass bulb or fusible link) releases, allowing water to flow from that sprinkler.
