1. An apparatus for performing peritoneal dialysis comprising:

  • a housing;

    a peritoneal dialysis supply bag supported by the housing, such that in use the peritoneal dialysis supply bag is located elevationally above a patient;

    a first valve for controlling gravity flow of fresh peritoneal dialysis fluid from the peritoneal dialysis supply bag to the patient;

    a second valve for controlling gravity flow of used peritoneal dialysis fluid from the patient to a drain, wherein the drain in use is located elevationally below the patient;

    a first pressure sensor positioned and arranged with respect to the gravity flow of fresh peritoneal dialysis fluid to provide a first reading used to evaluate a first gravity head pressure;

    a second pressure sensor positioned and arranged with respect to the gravity flow of used peritoneal dialysis fluid to provide a second reading used to evaluate a second gravity head pressure; and

    a controller configured to establish the first and second gravity head pressures due to a location of the peritoneal dialysis supply bag and a location of the drain using the first and second readings.
