A method of fracing a wellbore includes sealing a tubular within a wellbore at two locations defining an annular space thereby, opening at least two ports providing fluidic communication between an inside of the tubular and the annular space, flowing fluid from inside the tubular to the annular space through a first of the at least two ports, flowing fluid from the annular space to inside of the tubular through a second of the at least two ports, closing the second of the at least two ports, and pressuring the annular space through the first of the at least two ports.
