1. A system, the system comprising:
a fluid reservoir having sterilization fluid therein, the fluid reservoir being engageable with a plunger;
a connector in fluid communication with the fluid reservoir and with peritoneal dialysis tubing; and
a processor configured to:
expel, via an actuator operatively coupled to the plunger, the sterilization fluid from the fluid reservoir and into at least one of a first line of the peritoneal dialysis tubing and a second line of the peritoneal dialysis tubing via the connector by moving the plunger from a first position to a second position, and
retract, via the actuator, a substantial majority of the expelled sterilization fluid from the connector by retracting the plunger, after a predetermined period of time lapses, from the second position to a third position, wherein the third position is further from the second position than the first position and a further distance from the second position than a distance between the first position and the second position.
