Frequently Asked Questions

How do I find out the flush volume of my existing toilet?
A toilet flush volume, by gallons per flush will be stamped or etched in one of three places on a toilet. Sometimes, a toilet has a date indicated instead of a flush volume. Toilets manufactured before 1994 have a flush volume of 1.6 gallons or more. Tp find a manufacture year or flush rate, try looking in the following areas:
- On the walls inside the toilet tank.
- The flat area behind the toilet seat hinge, where the bowl meets the tank.
- The underside of the tank lid.
What is an Ultra-High Efficiency toilet?
Toilets sold and installed in California cannot exceed 1.28 gallons per flush. An ultra-high efficiency toilet uses 1.1 gallons per flush or less. Some models use only 0.8 gallons per flush, which is 37% less than the California standard.What do I do with my old toilets?
Toilets with flush rates that exceed the California Standard of 1.28 gallons per flush cannot be reused and must be disposed of appropriately. Program participants or their installing plumber/contractor are responsible for proper disposal of old toilets removed from their property. San Francisco residents can schedule a free bulky item pickup which includes old toilets through Recology. A list of registered construction and demolition facilities is available on the San Francisco Environment Department website. Please contact these facilities directly to confirm that they accept old toilets.My toilet is less than 10 years and is leaking. Can I get a rebate to replace it?
No, but the SFPUC provides free devices and guidance that may help you check and fix some leaks. Our conservation technicians may also be able to help during a free water-wise evaluation.
