1. A peritoneal dialysis system comprising:
a water purifier including a water outlet connector, a water recirculation connector, and an internal recirculation loop from the water outlet connector to the water recirculation connector;
a cycler; and
a disposable set operable with the cycler, the disposable set including
a pumping cassette including a water inlet port,
a water line in fluid communication with the water inlet port and the water outlet connector, the water line including at least one sterile sterilizing grade filter, and
a recirculation line in fluid communication with the water line downstream from the sterile sterilizing grade filter and the water recirculation connector, wherein the recirculation line and the internal recirculation loop absorb pressure upon a failure of the at least one sterile sterilizing grade filter.
