With the persistent drought in many areas and the general concern for water conservation, high-efficiency toilets have become more and more popular. As the number of gallons per flush continues to decline, concern continues amongst consumers about the quality of the flush. However, the technology behind each toilet has progressed over time to ensure a cleaner, powerful flush. Many tests are available for manufacturers to show plumbing professionals and their clients how well HETs flush the bowl cleanly with less water.
The parts of the country most afflicted by drought — notably California, Georgia and Texas — tend to be the leaders of the pack in terms of the trend toward water-saving products, particularly because these states offer generous rebates throughout the year. However, water-saving toilets also are accepted across the country based on their performance.
