1. A peritoneal dialysis system comprising:
a pressure chamber;
a disposable set including a flexible container located within the pressure chamber, at least one source line and at least one destination line;
a motive fluid pressurization device;
a motive fluid pressure sensor; and
a control unit in operable communication with the motive fluid pressurization device and the motive fluid pressure sensor, the control unit configured to (i) pressurize the pressure chamber on the outside of the flexible container to a desired positive or negative motive fluid pressure used to push fluid out of the flexible container through one of the at least one destination line or pull fluid into the flexible container through one of the at least one source line, respectively, and (ii) repeat (i) until a motive fluid pressure read by the motive fluid pressure sensor becomes or remains at least substantially constant when it is attempted to push fluid out of the flexible container or pull fluid into the flexible container, indicating that the flexible container is empty or full, respectively.
