I recently purchased a house that came with an RO system under the kitchen sink, but it wasn't hooked up. I replaced all the filters and bought a new air gap faucet. I made all the connections and turned the water on today and water FLOWS up and out of the small hole in the side of the faucet. I'm almost sure all the connections are correct, so I can't figure out why this would occur. It's not just a gurgling sound or a small dribble, it's flowing.
Has anyone ever seen anything like this?
