I would be way concerned about the diabetes insipitus and either find a way to collect a urine sample or take him to the vet and have them "hold" him there until they can get a good sample. I would never restrict water from any of my animals - we have three cats and two Yorkies and they have access to 6 different water bowls throughout out house, filled fresh daily. Like the OP said, if he is drinking that much water, there is a reason for it. I would definitely look further for additional medical conditions.
