An embodiment of a peritoneal dialysis system includes an enclosure, a door hingedly attached to the enclosure, a stepper motor housed by the enclosure, a solid pump piston in operable communication with the stepper motor and including a solid pump shaft attached to or integrally formed with a solid pump head, and a disposable unit contacting the enclosure and the door. The disposable unit includes a moveable membrane operable with the solid pump head. The stepper motor is configured to move the solid pump head towards and away from the disposable unit. The system further includes a position detection apparatus operable with the stepper motor and located to provide an output indicative of a position of the solid pump head relative to a reference position.
