Overview

Toilets are critical. Our daily comfort and well-being depend on toilets, even if we don't think about it. Toilets have a significant role in fostering a society that is more conscious of its impact on the environment. In fact, flushing the toilet accounts for 30 percent of all household water use, according to the EPA. Depending on the model, some older toilets might use up to seven gallons of water per flush. Every year, this equates to billions of gallons of water being wasted. The good news is that low-flow toilets are a straightforward fix.

It's healthier for the environment and your budget to use low flow toilets, which use between 0.8 and 1.6 gallons of water per flush. In several states and cities, low-flow toilets are now required in new construction, with refunds and incentives being offered to homeowners who switch to low-flow models. A number of well-known companies have responded by designing and manufacturing environmentally friendly toilets. So we did some research and came up with a short list of the best low-flow toilets on the market right now.

Buying Guide

Toilets, despite their simplicity, come in a wide variety of designs and styles. We decided to focus on a few simple criteria, such as water conservation, high-quality materials, and convenience of use, in order to streamline our search.

Water Conservation And Functionality

When it comes to low flow toilets, they should perform much like ordinary toilets, but with the added benefit of saving money on your water bill. Low flow toilets can vary widely in their quality. As a result, we sought out toilets that utilized less water while yet providing the same flushing performance as a typical toilet would provide.

Quality Materials

Considering that low-flow toilets can cost more than standard toilets, we sought out high-quality ones that were built to last. In addition, most of the models on our list are constructed using premium components. Each of the models on our list has the characteristics listed above, making it a sound financial decision.

Ease of Use

As strange as it may seem, we weren't just looking for toilets that were easy for the average user to operate. We also considered variables such as installation, cleaning, and upkeep. There was a lot of room for improvement in early low-flow toilet designs. Discarded garbage and a clean bowl were a problem for many. That's why we sought out newer designs that could withstand long-term use without malfunctioning.

Type Of Toilet: One-Piece Vs Two-Piece

One-piece toilets and two-piece toilets are also available. Is there more to a toilet than just two parts? In this case, it has to do with the tank.

The tank and the base of a one-piece toilet are one and the same. The Woodbridge is an example of a sleeker toilet.

A two-piece toilet features a tank and a base that are separate from one another, as the name implies. One-piece toilets may have a greater tank capacity. Because of all the crannies and crevices, they can be more difficult to clean. Because of this, they are typically less expensive.

Gallons Per Flush (GPF)

When shopping for a low flush toilet, gallons per flush is an important consideration. It's all about how much water the toilet uses when you push the flush lever.

The more water you save by using a toilet with a lower gallons per flush, the better. When contrasting low-flow toilets with standard toilets, this is a significant distinction. With the lowest GPF, the Niagra Stealth 2 is our most water-efficient toilet.

You can tell if your toilet is WaterSense certified by looking for the label. The EPA's optional WaterSense program requires manufacturers to have their toilets tested by a third-party body to ensure they fulfill the standards.

There are a lot of WaterSense-certified toilets on our shortlist. You can conserve water and the environment by replacing your old toilet with one of the best low-flow toilets!

Water surface

Because it rarely drew criticism or praise, I didn't give it much thought when reading customer reviews. To put it another way, the surface of the water is the area that is covered by water when it is not flushed. Due of the bowl's geometry, it does not define itself. A wider area of water, however, may be interpreted as a superior method of removing waste. As far as some people are concerned, it doesn't really matter

Noise level

Check out the sound for yourself by finding a pre-installed version online of the model you're interested in. Read the review instead, as the toilet search mechanism hasn't been invented yet (as far as we know).


FAQS

What Qualifies As A High Efficiency Toilet?

The maximum flow rate of a high-efficiency toilet is 1.3 GPF. The GPF for both the full flush and the partial flush in a dual flush toilet must be taken into consideration. Even with a full flush of 1.6 GPF, dual flush toilets can be promoted as high-efficiency toilets. This is due to the fact that a partial flush has a GPF of only 0.8. A GPF of less than 1.3 is the average of the two figures.

Do Low Flow Toilets Clog More Often?

Yes, low-flow toilets are more likely to clog, especially if the flushing system is inadequate. But don't be alarmed. If you're looking for a high-quality low-flow toilet, go no further than our top picks.

Are low flow toilets worth it?

Because it isn't LF, I don't think it's worth the effort to run and replace your current toilet. You should, however, consider a water-conserving toilet if you have just moved into a new home or your old one has asked for retirement.

How much do low flow toilets save?

To save up to 4000 gallons of water per year with only one water-saving toilet, you need the best toilet (and pay less, respectively). In the real world, it all comes down to how many people are regularly using it. Furthermore, the savings are much lower if you have a dual-flush model with only a partial low-flow flush. It's still worth it, though.

Maybe my old toilet is a low-flow too?

Chances are, if it was purchased and installed in the United States after 1992, it is. Low flow certification has been required in the United States since 1992. Then again, if you've had a monster from before that date, it could use up to 4 GPF or even more.


Conclusion

You may make a great difference by purchasing the correct toilet for your house. Both for your own sanity and that of the planet. Reduce your carbon footprint by installing a low-flow toilet in your home.

A low-flow toilet may be more environmentally friendly than a standard toilet, but only if your city has certain criteria or offers rebates. As with a typical toilet, if you are aware of the local regulations, you can make an informed decision based on your needs for space and preferences. We hope this article has provided you with all the information you need to make the move to a low-flow toilet right now!
