10 to 20 gallons per min per head figure a small room 8 foot by 12 foot has at least 3 (my 8x12 office actually has 4) so 30-60 gallons in one minute seems like a lot of water to me. Unless my math is failing me in ten minutes that is almost 12 inches of water on my office floor if it stayed in there.
