Based on appearance, it’s easy to think that all toilets are pretty much the same. But a peek under their lids reveals important differences, and recent innovations, that make shopping for this fixture something of a sleuthing exercise.
The drive to innovate started in 1994, when the 1.6-gallons-per-flush (gpf) mandate went into effect, replacing the 3.5 to 5 gpf that had been the norm. The pressure to save water hasn’t let up. Now there are high-efficiency (HET) and ultra-high-efficiency (UHET) toilets that use a mere 1.28 and 0.8 gpf, respectively. Yet, contrary to what you might expect, flushing efficacy has also gotten better; independent tests show that some UHETs can evacuate up to 800 grams (1.75 pounds) of solids with every flush.
