Toilet GPF stands for Gallons Per Flush, and it’s a term used to describe the amount of water a toilet uses per flush. Toilets are rated according to their GPF, so the higher the GPF, the more water the toilet uses per flush.
Most toilets made before 1994 used 3.5 to 7 gallons per flush, but newer models are much more efficient and use as little as 1.6 gallons per flush. This is why it’s important to know the GPF of a toilet before buying it. A higher GPF toilet will use more water, which can lead to higher water bills and a larger environmental footprint.
When shopping for a toilet, look for the GPF rating on the label. The U.S. Environmental Protection Agency (EPA) recommends choosing a toilet with a GPF of 1.6 or lower. This is because toilets with a GPF of 1.6 or lower use 20 percent less water than toilets with a GPF of 3.5 or higher.
It’s also important to note that the GPF rating only applies to the amount of water used per flush. It doesn’t take into account the amount of water used to fill the tank, which can be significant. Toilets with a higher GPF rating may use more water to fill the tank, so it’s important to factor that into your decision when choosing a toilet.
Toilets with a GPF rating of 1.6 or lower are considered “high-efficiency” toilets. These toilets use 20 percent less water than toilets with a GPF of 3.5 or higher, which can help save money on water bills and reduce your environmental impact.
