1. A peritoneal dialysis system comprising:
a cycler including a pump actuator;
a disposable set including
a pumping portion operable with the pump actuator,
a patient line positioned to fluidly communicate with the pumping portion, and
a drain container positioned to fluidly communicate with the pumping portion; and
a control unit configured to cause the pump actuator to actuate the pumping portion (i) to run a peritoneal dialysis treatment in which fresh dialysis fluid is pumped through the patient line to a patient and used dialysis fluid is pumped from the patient to the drain container, and (ii) at the end of treatment, to pump the used dialysis fluid from the drain container, through the patient line, to a house drain.
