You can ask your nephrologist if he would be able to get privilages for the Da Vita unit. I don't think that it's a big deal for them to do this. My old neph. Did it for me when I wanted to switch units
When my family went on my brother's Make-A-Wish trip to Italy for 3 weeks, my husband and I housesat at my family's farm. Apparently, they have weird shaped faucets because we couldn't find an adapter to attach the water line to any of the 3 downstairs faucets. We ended up attaching a RV-rated water hose to the water spigot outside, running it through the porch window, and attaching the adapter to that. It seemed very redneck, but it worked!
So it really is just a drain tube? Our bathroom is like 6 feet from our bedroom, and the living room is like ten feet maybe? Can you have the machine say in the bedroom and sit a few feet away in another room? I don't want to leave the machine in the living room, ya know?
