It's not a permanent hookup. If your sink where you get the water from has a threaded spigot, you can get plumbing attachments to just screw your unit in when time to make water. My unit was attached to the wall, with my yellow water line just hanging there waiting for me to attach to the spigot. The yellow was the input water. Red for waste (you'll likely discard 1 to 1.5 gallons for every clean gallon you make), and blue line into the filtered water receptacle. I used 2 trash cans. One for the blue line/filtered water, and another for the redline/waste water, which in turn was used in my washing machine.
Describe the sink you'll be getting the water from.
