Claim 7:
8. A peritoneal dialysis system comprising:
a source of water made suitable for peritoneal dialysis (“WFPD”);
a sensor located at the source of water;

a pumping cassette including a pump chamber configured to be actuated by the pump actuator, and
a mixing container in fluid communication with the pumping cassette,

wherein the control unit is programmed to:
mix the WFPD and the at least one concentrate by causing (i) the pump actuator to operate the pump chamber to pump a first amount of the WFPD to the mixing container, (ii) the pump actuator to operate the pump chamber to pump a prescribed amount of the at least one concentrate from the at least one concentrate source to the mixing container, and (iii) the pump actuator to operate the pump chamber to pump a second amount of the WFPD to the mixing container, and
cause a sample of the mixed WFPD and the at least one concentrate to undergo a test using the sensor, wherein the sensor is bypassed or used for a different purpose at least one of prior to or after the test.
