Depending on the model, toilets can flush anywhere from .6 (low-flow) to 1.6 (standard now) to 3.5 (older toilets).
Gate Tube Toilet Water Saver test conducted at the Stevens Institute of Technology, Center for Environmental Systems in Hoboken N.J., confirm:
A 2011 WaterSense designated 1.28 GPF Glacier Bay toilet fixture consumes on average 1.52 gallons per complete cycle.
A 1997 WaterSense designated 1.6 GPF American Standard toilet consumes on average 2.07 gallons per complete cycle.
A 3.5 gallon American Standard toilet consumes 4.23 to 4.31 gallons per complete cycle.
Consumers should be aware that Gallons Per Flush (GPF) does not a represent the total gallons consumed for a complete flush and refill cycle.
An old toilet typically uses between 3.5 to 7 gallons of water per flush. In contrast, modern toilets are designed to be more water-efficient, using about 1.6 gallons or less per flush. The significant difference in water usage highlights the benefits of upgrading to newer, low-flow models for water conservation.
The baseline flush rate for a water closet, commonly referred to as a toilet, is typically 1.6 gallons per flush (GPF) for modern, efficient models in the United States. Older toilets may have flush rates of 3.5 to 7 GPF. Newer high-efficiency toilets can use as little as 1.28 GPF while still effectively clearing waste. These standards help conserve water while maintaining functionality.
4.8 lpf stands for "liters per flush," a measurement commonly used to indicate the volume of water a toilet uses with each flush. A toilet rated at 4.8 lpf uses 4.8 liters of water for each flushing action. This measurement is important for assessing the water efficiency of toilets, as lower values typically indicate more eco-friendly options. Toilets with lower liters per flush can help conserve water and reduce utility bills.

The toilet uses about 1.6 gallons per flush.
About 1.6 gallons per flush
Modern toilets, 13 or 6 litres per flush. Older ones 22 litres per flush.
A standard 1999 toilet tank typically holds around 1.6 gallons of water. However, older models may vary in capacity, ranging from 3.5 to 5 gallons per flush.
Flushometer or tank and bowl?
You use anywhere from 1 cup of water to 5 cups of water to flush the toilet. This is per time you flush the toilet.
Low flow toilets use 1.6 gallons per flush. The new(2014) ones are 1.28
It takes 5-7 gallons of water per flush.
5 gallons
Compared to a 30 year old toilet? An amazing amount (I just installed two such toilets, replacing 30-year-old models). These are dual flush, and in the low flush mode - perfectly adequate for 70% of flushes - they use 1.3 gallons. The old toilets used almost 4 gallons per flush. A saving of 2.7 gallons per flush, times (how many??) flushes per day, times 365: You are easily talking thousands of gallons a year.
The amount of water used to flush a toilet can vary significantly depending on the type of toilet. Older models typically use around 3.5 to 7 gallons per flush, while modern, high-efficiency toilets use about 1.28 to 1.6 gallons per flush. Dual-flush toilets offer options for a lighter flush, using as little as 0.8 gallons for liquid waste. Overall, advancements in toilet design have greatly reduced water consumption in recent years.
depends on the kind of toilet and where you live. today's standard in America is 1.6 gallons. more efficient models will use 1.28 gallons. some even have a dual-flush option, 0.8 gallons for #1 and 1.6 gallons for #2.
