### Claim 3 (depends on 1)

The peritoneal dialysis system of claim 1, wherein at least one of the reusable fill container and the reusable drain container is rigid or semi-rigid.

### Claim 4 (depends on 1)

The peritoneal dialysis system of claim 1, wherein the reusable fill container or the reusable drain container includes a handle for manually transporting the containers when mated together to form the single unit.

### Claim 5 (depends on 1)

The peritoneal dialysis system of claim 1, wherein the reusable fill container is filled with a prescribed type of peritoneal dialysis (“PD”) solution.

### Claim 6 (depends on 5)

The peritoneal dialysis system of claim 5, which includes a patient treatment facility, and which is configured such that the reusable fill container is filled with the prescribed PD solution at a location remote from the patient treatment facility.

### Claim 7 (depends on 5)

The peritoneal dialysis system of claim 5, which includes a patient treatment facility, and which is configured such that the reusable fill container is filled with the prescribed PD solution at the patient treatment facility.

### Claim 8 (depends on 7)

The peritoneal dialysis system of claim 7, which is configured such that the PD solution is prepared at the treatment facility before the reusable fill container is filled with the PD solution.

### Claim 9 (depends on 7)
