A wet pipe sprinkler system uses automatic sprinklers attached to a piping system filled with water. The system is connected to a water supply so that water releases immediately from sprinklers once it is activated by heat from a fire. A wet fire sprinkler system has water in the piping and therefore is only used in areas where the ambient temperature is above 32\u02daF. In some cases where partial piping is exposed to freezing temperatures, such as a small loading dock, an antifreeze loop can be used. <\/p>\n","protected":false},"excerpt":{"rendered":"
