17. A peritoneal dialysis (“PD”) method comprising:
providing a dual lumen patient line including a first lumen and a second lumen;
providing a filter set including a filter membrane positioned and arranged to filter fresh PD fluid entering from a first line of the filter set, the filter set including a second line in parallel with the first line, the first line in fluid communication with the first lumen of the dual lumen patient line, and the second line in fluid communication with the second lumen of the dual lumen patient line;
positioning a pressure sensor so as to sense a static or substantially static positive PD fluid pressure in the second lumen while fresh PD fluid is pumped through the first lumen and the filter membrane; and
configuring a control unit to use the sensed static or substantially static positive PD fluid pressure in a pressure control routine for regulating fresh dialysis fluid pressure.
