I currently have a Toto Supreme (I think that's the model name...) in my basement bathroom. We periodically get sewer backflow from the city mains and our usual method of prevention, a rag stuffed in the toilet, is getting tiresome; especially when we're not home to do it and there's a huge rain.
I bought a simple backflow preventer that mounts under the toilet but the Toto Supreme doesn't really have the oomph to get things through. I've read here that the Toto Drake has a better flow and that while it has it's drawbacks, the Gerber Ultra-Flush can get most anything down it.
I'd prefer the Toto for it's style and lesser noise but even with a wider trapway, could it compare to an Ultra-flush in getting a good flow through what is basically a purposely installed minor blockage? Short of digging up most all of my small front yard and installing a proper sewer line backflow preventer, I'm stuck with this one - but I can't have guests embarrassed by getting their junk stuck in my toilet.
My assumption is that even with a good drop and a wider trapway, the Toto might not be able to 'power through' the preventer like it would an open sewer stack and that the Ultra-Flush, with its air-pressure might be the better choice, even if it's not the most aesthetic or gentle on the ears.
Any other ideas and suggestions are welcome.
