I am working my way through remodeling my house. I bought this toilet (CST454CEFG) 1.5 years ago, then it took a while to get around to installing it due to various problems with the remodel. Anyway, now that its installed, I love the look and the powerful flush, and the low water consumption.
However, I find that it gets skid marked almost every time you do a 2. I asked my roommate about it (to be sure it wasn't just my diet or something), and he said that he has the same problem. He spends a lot of time at his girlfriend's house, and said that he rarely has this problem on her fairly low end American Standard 1.6gpf (he couldn't remember the model). So it seems that there might be some issue with this particular toilet?
For this kind of money, I expect the toilet to rinse pretty well.
I've been living with it for a while now, just assuming that maybe it was me or that 1.28gpfs just can't be expected to do better than this, or something, but all the reviews I've read here and elsewhere seem to be pretty positive in this regard. Now, I am ready to buy a toilet for my powder room, where most of my guests will be using the toilet, and don't want a repeat of the problems I've had with my other one.
So, is there any recourse on the previous toilet (bought in June 2011 I believe, but only used for maybe 6 months so far), and any recommendations or advice for my powder room toilet? I was thinking of getting an Aquia, but I've seen a lot of reviews with this same complaint for that model, so thinking that I should stick with the 1.28 or maybe even go back to 1.6 for better bowl rinsing. Or do you think I just got a bad Drake II and I'd be good with another one?
