I'm planning on placing a stationary pressure washer in the corner of my garage. Nothing crazy like Obsessed Garage, but something mid-range to make washing cars more convenient. Currently, my water supply will come from the outside, which is not a big deal in the warmer months. I want to run a permanent water supply to the unit inside the garage. I do have a basement, and this is an attached (unheated but insulated) garage. It seems fairly simple, but since I'm no plumber, I'm sure it's more complicated than it seems.

Anyone done this or have any suggestions?
