I have a portable dishwasher. We also had a fancy faucet that it you couldn't attach it to. However, the faucet in the bathroom worked just fine. I don't suppose there's another one in a close enough place? Dragging the dishwasher to the bathroom got old after about a year, so we ended up just installing a new faucet in the kitchen. Mmmm but my python doesn't quite attach to it nicely. I've tried a bunch of different little rubber pieces (the name escapes me) to try and get a better seal, but no matter what you use or how tight you screw it, water still sprays all over the place. I just throw a wash cloth over it. It works.
Oh, and it's totally easy to install a new faucet. It's pretty simple and the kit I had came with really good directions. Also, it might be a good idea to take your python bit to the hardware store to make sure that it works with the new one if that's the route you go... of course on the other hand... I really did like the fancy faucet that was there before more than the new one.
