The Rain Bird 1804 sprinkler head is equipped with the pre-installed orange 1800 Pop-Top flush plug. This needs to be used to flush the line of debris that may have entered the system during installation. This is not a nozzle and must be removed and replaced with a spray or rotary nozzle after the line has been flushed.
