1. A method, comprising:
- applying vacuum pressure to a chamber of an air release device of a dialysis system, the air release device comprising a vent;
after applying the vacuum pressure to the air release device, measuring a pressure within a fluid line that is fluidly connected to the air release device; and
determining, based on the measured pressure, whether air is being drawn into the chamber of the air release device through the vent.

28. A method, comprising:
-
applying vacuum pressure to a chamber of an air release device of a dialysis system, the device comprising a vent; after applying the vacuum pressure to the chamber of the air release device, measuring a pressure within a fluid line that is fluidly connected to the device; and if the measured pressure is less than a certain pressure, indicating to a user that air is being drawn into the chamber of the air release device through the vent.
