The 7 Best Low Flow Toilets - Save Water In Every Flush

Low Flow Toilets

What are low flow toilets?

Imagine throwing a few hundred dollars into your toilet bowl and then flush it. That hurts right? In 1992, a US law was passed mandating all new toilets to be low-flow or low-flush to implement water conservation. From then on, low flow toilets sprung like mushrooms in the market.

Low flow toilets or also known as water-saving toilets became the new thing in household fixtures because it significantly reduced water consumption and still able to clean bowls like full-flush toilets. A toilet is considered low flow when it uses not more than 1.6 GPF (gallons per flush).

The said law is supported by the US EPA (US Environmental Protection Agency), which provided WaterSense certificates to those products that meet the standards.

Although a bit lower in price than our number 2 spot, it is worth every penny for a smart toilet with all the right features.

Finally, a water-saving toilet brand that has a fighting chance is squeezed in at number 7. Kohler is also a popular trademark in kitchen and bathroom fixtures. And here is a product that is also water-efficient.

This Kohler toilet is using 1.28 GPF and has the comfort height which means it is user-friendly and can be installed in public establishments. It also has a powerful flush that keeps your bowl clean.

We can always say the water-saving attributes of low flow toilets are really economical and nature-friendly. The GPF can easily be calculated to the amount of water you are saving annually. For example, the 1.28 GPF toilets can save 16,500 gallons of water per year. So, a 0.8 GPF toilet can save approximately 26,400 gallons of water per year. Now, that is more than the amount of water in a regular-sized swimming pool. Water-saving toilets are simply the best!

Normally, people do not really care about the GPF (Gallons per flush) as long as they are told that the toilet is water efficient. That is why it is best to refer to articles and google your way to knowing the best low flow toilet that is available for 2020 or the current year you might be purchasing new water-saving toilet.

Before, the US EPA recommended and tagged toilets that are below 1.6 GPF as water-efficient and carry the WaterSense certificate mark. But times are always changing. Due to the pressure-assisted flush mechanism, it is now possible to use less water to push bodily wastes down the drain. 

You can see that there are already 0.8 GPF toilets and some of them do not cost a fortune. Well, some smart toilets, which are also low flow toilets, are really expensive but you will always get the added features you are paying for. 

But if you are on a budget and still want that water-efficient toilet, go ahead and purchase the Niagara 77001WHCO1 Stealth 0.8 GPF Toilet. It is so far the best water-saving toilet for your home - adding savings and subtracting expenses.
