WATER: How do I know if my facility has low-flow toilets?

Print Email

Ultra low flow toilets (ULFTs) are toilets that use 1.6 gallons per flush (gpf). In 1995 the National Energy Policy Act (H.R. 776) mandated ULFTs nationwide. Today, even more efficient toilets called high efficiency toilets (HETs) are available that flush with 1.3 gallons of water.

In order to qualify for Green Business recognition, businesses must use ULFTs or, preferably, HETs in their facility. Businesses that need to install new toilets must use HETs, and rebates are available for installation. For more information, please visit SFPUC or call 415.551.4730.

Toilets made after 1994 will have a stamp on the upper rear of the bowl. You might also find a date impressed in the ceramic tank or a gpf stamp from the manufacturer on the inside rear of the tank. If the stamp is not present, your toilet is probably not a low flow toilet. Additional information on identifying the flow rates of your fixtures is available in the Resource Conservation Guides.
