High-efficiency toilets save water and money, and are easier than ever to shop for thanks to WaterSense labeling. In the same manner as that now-famous Energy Star logo, the WaterSense label tells you a toilet or other bath fixture will conserve more water and perform more efficiently than one without it. To earn the WaterSense mark, products are tested to meet stringent guidelines determined by the EPA with involvement from water utilities, manufacturers, and test labs, leading to solutions
Alt=High-Efficiency Toilets Save Water and MoneyTo find high-efficiency toilets (HETs), shop your favorite home center or fixtures dealer. A great improvement over the previous dual-flush and low-volume models, HETs cut down on the current standard maximum of 1.6 gallons per flush (gpf) by 20 percent to 1.28 gpf. In case this doesn’t strike you as a dramatic savings, consider that pre-1994 model you’ve got somewhere in your house, flushing away 3.5 gallons of water at a time. With a family of four in residence, that toilet is using around 26,000 gallons of water every year, and replacing it with a WaterSense-labeled HET could reduce water usage by 60% and save you at least $55 annually in water bills–enough for the HET to pay for itself within a few years!
In other WaterSense-qualifying features, high-efficiency toilets must be able to flush away a minimum of 350 grams of soybean paste (you get the idea) and include a flush valve flapper or seal on the flush with the test-proven chemical resistance to ensure that exposure to chlorine and hard water won’t lead to leaks over time. The overall design presents flush volume from being adjusted by the consumer either on purpose or inadvertently (through replacement of tank components), and though the hydraulics differ from traditional toilets, they allow for a very similar installation process. Independent tests have also determined that HETs don’t cause dreaded drain-line-clogging issues.
More WaterSense products are on the way, with bathroom faucets and irrigation system components currently in testing, so we can all look forward to an abundance of ways to conserve dollars and natural resources.
