Most low usage toilets work very well these days, and they don’t overflow and flood like the old ones did.
However, the regulations should be relaxed.
Most water is used by agriculture and industry, not households.
This has also been our experience.
During a main bath remodel several years ago, I replaced our original commode with a lower-end American Standard elevated seat, elongated bowl model. It empties everything with a single flush and has not required plunging a single time.
Last year, I replaced the unit in our half-bath with a Member's Mark (Sam's Club) elevated seat, elongated bowl toilet. This one has two pushbuttons, one for liquids and another for solid waste. It also works exceptionally well, rarely requires a second flush, and I'm happy to be finished with the overflows that happened fairly frequently with our older toilet.
I don't like being regulated into design changes by ECO leftists, and sympathize with those who have difficulty with the newer fixtures, but I've been very satisfied with ours.
