Hi all. Just joined this site today with the help of abikerboy. I wanted to touch this post because I am the man with the display in his shop. I want to say that this display has nothing to do with advertising and is all about science. This display is in my back shop and not even in reach of the general public. It was set up by my warehouser, the water control board and a local college to demonstrate water useage. We just added a little twist with the foam balls and in doing so, discovered the trapway flaws. I do business honest, so I discuss any flaws I find in a product with my customers. At my age, Im no longer in this to make a killing. I keep this place going because somehow it keeps me going, and the customers Ive had for the last 35 years keep us both going. There are two other displays here as well. One has an assortment of faucets, kitchen and bath, and the other display is armed with shower heads. The flow lines to each are monitored by computer flow meters. Very interesting to watch! If I were going to push anything for financial interest I would push the el cheapo contractor's toilets. That is what every one wants. To most of the public it is all about the bottom line, and I could make a killing on cheap products! I did recomend the Ultramax one piece to abikerboy, but he wouldnt go for the one piece look, so I recomended the Cimarron. I did advise him to stay away from the American Standard two piece as I have had many that would crack at the tank to bowl juction bolts. I find many of the test results that are posted throughout the web very educating but I make my own suggestions based on my own experiences. My idea on trap way flaws depends. If there is no glazing as I read in one post, return it and get another. If you find some small defects or minor bumps, use it and dont worry. There is no such of a thing as a perfect product, but total duds are very rare as well, otherwise the manufacturer would no longer exist.
