Have you ever walked into an office and noticed a fixture on the ceiling, with tubes snaking their way down to the walls? Chances are, you have seen a ceiling water sprinkler. Also known as a wet pipe fire protection system, a ceiling water sprinkler is a powerful tool in reducing fire damage and saving lives when used correctly. It is a type of automatic sprinkler system made up of sprinklers that are installed in the ceilings of buildings to douse fires with water from pipes connected to a water source. When heat from a fire sets off the sprinklers, water pours out onto the flames below, lowering the temperature of the environment and quickly putting out the fire.
