Ultra-Low Flush Toilets

In the 1980's improved technology resulted in an even lower volume toilet: the ultra-low flush. Such toilets use 0.8 to 1.5 gallons per flush.

On one hand, these toilets offer remarkable savings. They use no more than 9 gallons per six flushes, compared with 33 for a non-conserving toilet-- a savings of 73 percent. Toilets of 1.6 gallons per flush or less came to be required on all new construction.

This requirement, however, proved to be a mixed blessing. It contained no specific performance requirement. New designs that worked well at the low flows were less common than “quick and dirty” modifications of existing designs. The poor performance of old designs gave all low-flow toilets a bad name and sometimes led to a “black market” in older toilets.
