Read More- 1.28 VS 1.6 which one is best for the future. 

Calculate average water consumed by 2 members in one house, use once the toilet then how much water will waste.

1 Gallons = ~4.55 liters
If the 2 members in a house flush the toilet, then 2 x 4.55 = 9.1 liters means 2 Gallons per Day.

In the whole year, 365 x 9.1 = 3321.5 liters of water means ~730.63 gallons of water per year will consume.

1.28 GPF = ~5.81 liters. For 2 members 2x 5.81 = 11.62 liters = ~2.55 Gallons of water per Day.

In the whole year, 365 x 11.62 = 4241.3 liters of water means =~932.96 Gallons of water per year.

For, 1.6 GPF = ~ 7.28 liters water . For 2 member 2 x 7.28= 14.56 liters =~ 3.20 Gallons of water per Day.
