Problem is, Junior says Toto toilets are no good and he's dad's plumber. Sure, most of us regulars on this forum know that Toto toilets are the premier toilets, but Jr the Plumber knows better so who's dad going to believe. I just don't know why he bothered to ask about which Toto would be the best. He'll end up with a AS or Kohler from the Depot and assume the clogs are normal for low flow toilets 'cause Jr. says so.
In fairness, in the first post, he said that his son said that he "should not buy a Toto". He later explained that his son noted that Totos have a 3" flush valve and an enlarged trapway, and said that there were other toilets that have these features today for less money, which is true.
And we also know that the son, right or wrong, has his Dad's best interests at heart, and doesn't want him to overpay.
So what we need to point out is that, yes, other brands have made changes in their bowls so they can say "WE HAVE THAT!!!" or, like the AS Champion "Not Really 4", can say "Ours is bigger" or "Ours go to 11!"
But we should also point out that the DESIGN of the trapway is important, not just its diameter, and Terry has explained why Toto's is the best. We can also point out that the defect rate on Totos is much lower than the rest of the industry, and that, unlike many of the other brands, they don't try to unload defective merchandise (like that poor guy with the unglazed portion of his bowl or the tank that Terry showed that had a defect that had been like sanded or something). And we can point out that unlike, say the Champion "Not Really 4", the Toto uses a standard flapper and fill valve. We can point him to the proper source of inexpensive replacement parts (Korky 528MP Valve and "Fits Toto" Flapper, all available at Lowe's.) And, finally, we can note that the Drake flushes golf balls just like the Champion (there's a video on youtube).
So these are reasons that may justify the Toto's higher price. And we can then point out that Totos are actually available through many channels at an affordable price.
I think that Terry has covered the issue of which ones leave fewer skid marks, and we can say that if he likes the look of the Drake II and Ultramax II, he can buy those with confidence, because they come standard with CEFIONTECT.
And we can wish him good luck and thank him for his kind words about this forum.
