To demonstrate, he piled 16 golf balls into a model known as the Cadet 3 Flowise and pushed the lever. Faster than you can say "fore," they disappeared.
"Water efficiency has a black eye based on past performance, but things have gotten much better," said Barnes, a product representative for American Standard, whose national "Responsible Bathroom Water Conservation Tour" was in Evans on Monday.
Toilets of yesteryear used 3.5 gallons per flush, and the mandatory transition to just 1.6 gallons spawned inefficient models that still draw complaints, he said.
Today's growing emphasis on water conservation has spawned vast improvements in toilets, faucets and shower heads that could help Americans save billions of gallons of water.
The mobile demonstration studio was at W.A. Bragg & Co. in Evans as part of a 300-stop tour of sites across the U.S., Canada and Mexico.
Technology and public demand both accelerate improvements that save water, Barnes said.
The goal of the tour is to show how an average four-person household can reduce annual water consumption by 48,326 gallons simply by upgrades to water-saving fixtures.
Toilets, in particular, have come a long way, thanks to redesigned traps and flush valves that compensate for less water. Field testers, he added, use material as varied as miso paste and hot dogs to evaluate flushability and performance.
"American Standard has invested a lot of time -- and technology," he said, noting that 75 percent of household water consumption is bathroom-related.
