    Quality Craft. 3000 Series toilets are WaterSense certified and MaP approved to dispose of 900 grams in a single flush, according to the company. The toilets feature a 3.3-inch flush valve that maximizes flushing force and a rim wash to clean away debris and bacteria, the manufacturer says. The 2?1/8-inch trapway prevents plugging. A dual-flush feature lets users push one button to flush liquids at 1.1 gpf, or a second button to flush solids at 1.6 gpf. The elongated, comfort-height bowl is ADA approved. 604.575.5550. www.qualitycraft.com.

    Toto. One- and two-piece Gwyneth high-efficiency toilets feature a 1.28-gpf gravity-fed double-cyclone flush engine. The toilet is WaterSense certified and qualifies for select water utility rebate programs, the manufacturer says. The unit is 17 inches from base to seat, and it cleans itself during each flush as water from two nozzles removes debris and bacteria from the concave rim channel, the company says. 888.295.8134. www.totousa.com.

    Foremost. The All-in-One elongated version of the dual-flush, 1000 Gram HET toilet is WaterSense certified and uses 1.1 gallons of water for liquids and 1.6 gallons for solids, saving up to 16,000 gallons of water per year for a family of four versus 3.5-gpf models, the company claims. The company’s patented power-assisted flush system uses water to compress air and remove the maximum amount of solid waste. Antimicrobial protection is built into the toilet. 800.443.1410. www.foremostgroups.com.

    Caroma. The company claims its Sydney Smart dual-flush, WaterSense-certified toilet saves more than 18,000 gallons of water per household per year compared to 3.5-gpf single-flush toilets, and more than 5,000 gallons over 1.6-gpf, single-flush toilets. Users may choose a 0.8- or 1.28-gallon flush, which averages out to 0.89 gallons per flush. The toilet features wash-down flushing and a trapway nearly twice as large as the industry average. 800.605.4218. www.caromausa.com.

    Kohler. The company’s WaterSense-certified Saile toilet is a seamless, one-piece, dual-flush unit designed to eliminate liquid or bulk waste with a single flush. The two-button actuator lets users choose 1.6 or 0.8 gpf. A family of four can save, on average, up to 8,000 gallons of water each year with the 0.8-gallon flush (versus 3.5-gpf models), according to the company. The toilet seat features an over-molded lid that covers the seat ring for a finished look. The device has a skirted toilet and is designed for flush-to-wall installation. 800.456.4537. www.kohler.com.

The requirement appears to be working. Stephanie Thornton, who oversees partner outreach for the WaterSense program, reports the EPA has not received any complaints about the newer toilets.

In fact, notes John Koeller, a Chicago-based technical adviser to the Alliance for Water Efficiency and a third-party tester, the average HET outperforms WaterSense requirements by flushing 650 grams.

Improvements, such as better hydraulic designs, larger valve openings and trapways, and jet-fed bowls, mean far fewer clogs or double flushes. “Toilets are no longer designed by model makers who are looking for aesthetics,” says Koeller. “They’re designed by engineers who are paying attention to the hydraulics.”

And that makes HETs easier to sell than the troubled first versions of 1.6-gpf toilets that hit the market in 1994, say pros and manufacturers.

It also helps that consumers don’t necessarily have to pay more. Research shows that higher efficiency does not mean higher cost; like traditional models, there is a range from basic to premium. Installation is the same except for a few high-tech models with electrical components.

HETs also can be used to earn credits under the LEED for Homes standard and the NAHB Model Green Home Building Guidelines.

Still, not every contractor is hurrying to install HETs. Melrose, Mass., plumbing and HVAC contractor Albert Cairns says pressure-assisted HETs, which use technology similar to that in airplane toilets, flush in a big, quick swoop and are noisy. “I wouldn’t install them in my own house,” he says.
