A Sprinkler, in Liverpool, is a device that helps spray water. It may also refer to an irrigation sprinkler, which is used for irrigation of lawns or crops or a fire sprinkler system, the entire systems of pipes and sprinklers intended for fire suppression within buildings. Irrigation sprinklers are used on farms, golf courses, and yards, to provide water to vegetation and plants in the event of drought. Sprinklers that spray in a fixed pattern are generally called sprays or spray heads. Whereas, a fire sprinkler is a device that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been reached.
