How to Choose

What research and programs say about high-efficiency toilets

Scientific studies and government programs consistently show that modern high-efficiency toilets can cut household water use and reduce the energy required to treat and transport water. Evidence from water utility reports and efficiency programs highlights that replacing older high-flow toilets with 1.28 GPF, 1.0 GPF, or ultra-low flow models significantly lowers indoor water consumption and often pays back its cost through lower utility bills and rebate incentives. Independent testing protocols evaluate flush performance and clog resistance to ensure that water savings do not come at the expense of function.

Independent testing and certification programs, such as WaterSense-equivalent protocols, verify that high-efficiency toilets meet performance and water-saving thresholds.

Replacing older 6 GPF or 3.5 GPF toilets with modern low-flow models commonly reduces toilet-related indoor water use by substantial margins, often saving households thousands of litres per year.

Lifecycle and municipal utility studies note secondary benefits including reduced energy and chemical use for water treatment and lower peak demand on local sewer systems.

Many Canadian municipalities and provinces offer rebate programs for qualifying high-efficiency fixtures, improving the return on investment for homeowners.
