The ABC’s of Plumbing – Dual-Flush Toilets

In response to water conservation concerns in the 1990’s, low-flush (or high efficiency) toilets were introduced to significantly reduce the number of gallons used per flush (GPF). Low flush toilets use 1.3 gallons per flush, while a regular toilet 1.6 or more gallons per flush. The average US home will save US$90 per year, and $2,000 over the lifetime of the toilet, according to the EPA. To be eligible to the EPA’s Water Sense label, a toilet cannot be more than 20 percent less than the maximum allowed.

As the name suggest, a dual-flush toilet is uses two buttons or handles to flush different amounts of water. Depending on the design, the amount of water can be cut in half. While they can save a significant amount of water, the downside to dual-flush design is added complexity with more parts, as well as higher initial cost.
