Toilet Replacement Program Gallons per Flush
How to Determine The Number of Gallons Per Flush/Per Toilet
Toilets made before 1992 use anywhere from 3.5 gallons per flush (GPF) to 5
GPF. In fact, since 1992 the only toilets permitted by law to be sold in California
use 1.6 GPF (called ultra low-flush toilets or ULFT).
To determine the gallons-per-flush on your toilet, check the toilet's GPF
stamp located on the toilet bowl rim. If it's not there, then check
the toilet's make, model, and date of manufacture by lifting the toilet tank lid
and looking for the manufacturer's imprint stamp located at the inside back
of the tank. If the date of manufacture is 1980 or earlier, it's GPF is probably
five or higher; if it was built between 1981 and 1991, then it's likely a
3.5 GPF toilet; and if it's manufacture date is 1992 to the present, it should
be a 1.6 GPF and is already water-efficient.
