Cupertino Plumbing is excellent. I've had them do a number of jobs for me, including re-piping the whole house. They did an excellent job. It was very effective cost wise. They also did two toilets for me among other things. The workers are friendly and very businesslike. They had a job to do and they did it. I was thinking about having them put a new sink in my kitchen too, but I haven't decided yet.
