CTDI Corporation has been distributing toilets in Marin County for about 3 1/2 year. We have distributed primarily the Toto c703 and 704 models with great customer satisfaction. Some of our customer want to opt for the rebate program and buy their toilets from retailers. I often give them a copy of your "Toilet Pages" for reference. (I hope I am not violating copyrights!) One feature of toilets which I believe makes all the difference in performance is the trap size. When customers go to their retailer, no one seems to be able to tell them what the trap size on the fixtures is. I belive that the Toto has a 2 1/8" trap, and out of the 15,000 we have distributed, I have had only one clog---that in a restaurant where people tend to throw everything into them. So...how can the consumer get this information easily without having to contact every manufacturer?
