1. A peritoneal dialysis cassette, comprising:
a housing enclosing one or more flow paths;
one or more rotary valves configured to transfer fluid therethrough,
wherein the one or more rotary valves are configured to selectively direct the fluid through the one or more flow paths;
wherein the one or more rotary valves have a plurality of positions,
wherein at least one of the positions is a closed position that prevents flow of the fluid through the one or more rotary valves,
wherein the one or more rotary valves each contain two openings on opposite sides of each valve of the one or more rotary valves, the two openings defining a single flow path disposed through each valve of the one or more rotary valves,
wherein an upper flow path of the one or more flow paths is configured to fluidly connect to the single flow path disposed through each valve of the one or more rotary valves along a larger arc adjacent to each valve of the one or more rotary valves than an arc adjacent to each valve of the one or more rotary valves to fluidly connect to a plurality of lower flow paths of the one or more flow paths.
