SFPUC residential customers are eligible for cash rebates when they replace their high-flow toilets with new efficient models. Toilets with a flush volume of 3.5 gallons or greater are considered a high-flow model. SFPUC rebates up to $125 for an approved High-Efficiency Toilet (HET).

ULFT vs. HET?

It has been more than decade since Federal laws have mandated that the toilet flush volume for models sold in the United States could not exceed 1.6 gallons per flush. These models are called Ultra-Low Flush toilets and they are the highest flow models available on the market today. Prior to this standard, toilets flushed at 3.5 to 7 gallons per flush.

High-Efficiency toilets (HET) are fairly new to the American market but have long been used overseas. The HET flushes at least 20% below the standard model. Many HET’s are dual-flush toilets, which have two separate flush volume options.
