The toilet is one of those things that we all need and use on a daily basis, but seldom hear about or discuss. However, when a toilet isn't working well, it makes our lives more difficult so choosing the right one is really important.  And, the dual flush toilets will help improve your convenience during the moments you spend on them each day and help you conserve water as well.

Thanks to their increased water-saving capabilities, dual flush toilets have been highly common in recent years. They have two buttons that designate two layers of water, helping to fully remove the solid waste in one push. The best thing is that there are two different transfer choices for adjusting the volume of water.

If you have the intention of getting new toilets for your home, spending a few minutes on this article will help you choose the best one.  

Buying guides

Dual flush toilets refer to a smart way to save water thanks to their outstanding function, but besides that, there exist a lot of other criteria when coming to buy the best one. Below is a list of all the major considerations you can make during your search. 

1. Types

Most toilets are divided into two types: one-piece and two-piece toilets.

For a long time, the two-piece has been popular. In this type, the bowl and tank are sold separately and must be joined together. The majority of people like them because they are less expensive.

Another type is the one-piece dual flush, which is available in a variety of styles. It is designed as a whole unit, combining a bowl and the tank together. TOTO Neorest is typical for this type. It is no need for you to waste time and effort to attach the two pieces. Most people prefer this because it comes with no seam between the bowl and the tank, therefore, fewer bacteria are seen, and cleaning stuff is much better.

2.  Size and shape

Toilet bowls are usually available in two shapes: elongated and round. 

Round toilets are a bit narrower and therefore easier to maneuver into compact bathrooms and narrow spaces. They are much less expensive than elongated ones, so they are often used by those trying to save money.

Elongated toilets have a more oval appearance and are almost two inches longer than rectangular toilets, take TOTO AQUIA IV  as an example. Elongated ones are 18 to 19 inches in length, while round ones are 16 to 17 inches long. They are considered more relaxed because they are significantly larger. You'll be satisfied with an elongated bowl if you have space and comfort since it is more valuable to you than price.

3. Installing types

There are 2 common types when coming to the installation of a dual flush toilet.

Floor-mounted: Most of the toilets you'll see are expected to be floor-mounted, such as KOHLER-K-3987-0 Wellworth. This means that during construction, it is directly connected to the floor. They have a good structure that fits well, and the majority of people are satisfied with a floor mount model.

Toilets with a Wall Mount: Wall-mounted toilets aren't as common as floor-mounted toilets, but they're gaining popularity due to their tidy, modern appearance. These are fixed to the wall and remain above the ground rather than being placed on the surface.

This style of toilet takes up less room due to the way it is built, and many people like it aesthetically. They also make bathroom washing easier so you can vacuum under them because there are fewer crevices to clean on. They are, however, more costly and have a more difficult implementation process.

4. Material

The majority of dual flush toilets are made of porcelain, ceramics or plastic. The most used material used in the manufacture of toilets is porcelain and ceramic like Swiss Madison Well Made Forever SM-1t254 St. Tropez One-piece Toilet. This is due to the fact that both of them are durable, have a watertight seal, in which porcelain is relatively inexpensive to manufacture. Plastic toilets, on the other hand, are comparatively rare due to the difficulty of producing a plastic that is equal to porcelain or ceramic in terms of consistency.

5. Flushing technology

Flushing technology has seen a number of advancements. We all know that the flushing mechanism is an essential feature of a toilet, even among all of its parts. There are two types of normal flushing systems: pressure-assisted flushing and gravity flushing.

The water forced into the bowl by pressurized air is the pressure-aided flush system such as American Standard H2Option Dual Flush Round Front Toilet. It makes use of both water and high-pressure air. As a result, when you flush, the pressurized air flushes down the waste with a lot of energy. This machine produces a loud flush and is quite expensive, but it is more effective and requires less power.

The method of gravity flush is more general and easier. The system is filled with a flush valve that uses gravity to produce flushing pressure through the use of water weight. The waste goes through a trap in the S-form, and the flush is completed by a siphoning operation. This model is cheaper and has a quieter sound.

FAQs

1. How do dual flush toilets work?

Dual flush toilets do just as their name means; they have two flushing options. For solid waste, high volume flushes are employed, while for liquid waste, low volume flushes can be used. This dual-flush design helps reduce the average flush volume enough to achieve high performance or very high-efficiency requirements.

2. How much water is used by a dual flush toilet?

Before 1980, toilets used 5 to 7 gallons of water, on average, some with a flush of 8 gallons or more. From 1980 to 1992, in general, 3.5 gallons of water per flush were consumed in toilets. Federal legislation was introduced in 1994 to improve water quality, whereby the average toilet use per flush was 1.6 gallons or less. The total volume of water used in modern toilets currently stands at approximately 1.1 gallons per flush.

3. Which button do you press on dual toilets?

There are flushing options in a dual flush toilet, a lever or a double button for a dual flush mechanism. Most toilets contain directions that are visible on the toilet or in the manual of the user. In case of uncertainty, these instructions should be followed. 

For the toilets with push buttons in the top lid, the smaller two buttons are used to wash out the liquid waste. The bigger button is suitable for vast quantities of waste, including toilet paper. If the toilet has a level, upwards movements are for flushes that are low in volume, suitable for water waste, and down the level is for flushes of high volume, like solid waste, including toilet paper.

4. How long does warranty coverage of dual toilets last?

The majority of these toilets are very pricey, so make sure they come with a warranty. And, regardless of how much you pay, it's still better to get a model that's insured for a long time. Most of the dual toilets come with a 1-to- 5-year warranty.  Even though some of these vendors have extensive coverage, be a smart shopper and search the warranty first to avoid having to deal with replacements.

5. How do you tell the difference between a single flush and a dual flush toilet?

A single flush toilet has just one flushing alternative which uses the whole tank of toilet water to flush all liquids and solids. A dual flush toilet has two choices for flushing, one for liquid waste and the other for solid waste. It uses  0.8 gallons for liquids and 1.3 to 1.6 gallons for solids.

Final thoughts

While the best dual flushing toilets are more costly than standard toilets, they will save you money in the long run. You will see a drop in your water bill over time. 

Below is the list of top 5 dual flush toilets for you to refer to:

  • Best overall

Swiss Madison Well Made Forever SM-1t254 St. Tropez One-piece Toilet is the best option if you are looking for a toilet. Its soft-closing lid keeps the seat from slamming shut and making a loud noise. This is particularly useful at night. As other dual flush toilets, this product offers two flush options for a dual flush system: absolute flush or partial flush for solids and liquids respectively. The lustrous and attractive design of this product will enhance the elegance of every bathroom as well as make it easier to install.

  • Best for cleaning

Not so many people are happy to clean a bathroom, but the dual flush toilet of TOTO AQUIA IV will minimize the cleaning time. This device has a skirted trapway to prevent the grime-attracting contours of the normally open trapway. TOTO's patented CEFIONTECT glazing is used on the interior of the bowl to prevent dirt, germs, and mold from adhering to the floor. It basically cleans itself when combined with the TORNADO FLUSH through toilet cleaning.

  • Best one-Piece toilet

TOTO Neorest, with its one-piece design and elongated bowl, is the perfect option for a modern look. This style is a beautiful combination of elegance and environmental friendliness, with all the new innovations. Despite the fact that it uses less water than the average toilet, it flushes regularly and automatically.

  • Best for preventing clogs

KOHLER-K-3987-0 Wellworth is small and compact, which enables it to fit into most bathrooms, thanks to its round front bowl. It is also very comfortable despite the lack of comfort height. However, the great part is that you will never have to use the plunger. Its high flush power and glazed trapway ensure that the waste is permanently cleared by a silent, fast, and effective flush.

  • Best for budget

The two-piece dual flush toilet of American Standard H2Option Dual Flush Round Front Toilet is the best model you can obtain at a reasonable cost. It has a push-button actuator that can be chosen for flushing down liquids by 0.92 gallons and solids by 1,28 gallons. It also has a powerful siphon jet that guarantees that everything is flushed properly. While two-piece toilets are hard to clean, the manufacturer used porcelain to make the surface in order to remove stains, germs, and mold.

By reading through the information above, we hope you can choose the best dual flush toilets for your house.
