nxstage Dialysis machine to be hooked up to our washer

[Matt Ransom]

My tenant just texted that she would like to hook up the nxstage dialysis machine to our washer. It is apparently a new device. She said there is no drilling on the walls or pipes. Has anyone ever had any experience with something like this? Will I be held medically liable if our "older" washer fails at some point? Any advice is appreciated.
