1.28 VS 1.6 GPF Toilets

From the looks, you might think that all toilets are the same. But this is far from the truth as they have a lot of variations(Like Comfort height vs Standard height, 1 Piece vs 2 Piece, Round vs Elongated, Dual Flush VS Single Flush). And one of the major differences in flushing toilets is their water consumption rate per every flush. Some use 1.6 gallons of water per flush while others use 1.28 gallons of water per flush. Read this 1.28 VS 1.6 GPF Toilets article to find the difference between them.

The first flushing toilets used 3.5 to 5 GPF, which was later replaced by 1.6 GPF in 1994. But with the pressure to save more water, the high-efficiency and ultra-high-efficiency toilets that use 1.28 GPF and 0.8 GPF, respectively, have been introduced again.

1.28 GPF Toilet

With the need to save more water for an eco-friendly environment, manufacturers have come up with high-efficiency toilets that help you save more than annually. 1.28 gallons per flush toilets are becoming very popular by the day as they use less water than the recommended 1.6 gallons per flush but are still very effective in clearing of waste.

Pros:

  • You will save at least 4, 000 gallons of water annually
  • You may stand to get rebates in some states if you install them

Cons:

  • Have more cases of staining and clogging
  • Most of them don’t clear a large mass in one flush

1.6 GPF Toilet

This is the federal standard but it is not recommended in some states like California and Texas. Toilets that feature a 1.6 gpf are more effective as they clear waste easily in just a single flush. However, even though these toilets use more water, they don’t leave behind stains or have to be flushed twice to clear waste like in some 1.28 gpf toilets.

Pros:

  • Most of them clear a large mass in one flush
  • The toilet experiences fewer clogs and stains

Cons:

  • They consume more water than their counterpart

Which is Better? 1.28 or 1.6 GPF?

Depending on where you live, you may find one of these toilet models to be ideal for you. Regardless of which toilet you choose, ensure that you go for the one that meets your needs. If you want to save water, then I would recommend the 1.28 gpf toilet, but if you want a more effective powerful flush toilet, then you should go for the 1.6 gpf toilets.

All-in-all, these two toilet models are amazing in performance and will help you save water to some extent. Consider other features so that you can end up with a toilet that meets your needs and demands.
