American Standard H2Option Siphonic – Dual Flush Normal Height Toilet


Dual Flush Normal Height Toilet

The H20ption Siphonic Dual Flush from American Standard is another option in the comfort height category of dual flush toilets. A gravity-flush toilet is a water-efficient toilet that uses a dual flush to reduce water consumption. With an ultra-high efficiency and the capability to make use of only a small amount of water, the Ultra-High Efficiency Toilet will save you the most water and give the highest savings.

The white colored H2Option Siphonic Dual Flush toilet has a size of ‎27.75 x 15 x 30 inches. Moreover, It is made up of ‎Vitreous China material. Its rounded shape increases the beauty of the toilet and its weight is also bearable.

This right height toilet from H2Option offers unbeatable comfort thanks to its 16-1/2″ rim height which is higher than a standard toilet and therefore provides unbeatable comfort. The ultra-high efficiency toilet is designed to decrease the amount of water that is wasted as much as possible.

It seems that the ceramic on this toilet is in excellent shape with no visible flaws and it appears to be thin but this could be a result of the fact that it replaced a much older model. There is a considerable reduction in the size of the tank, it is more compact but not shorter from my understanding.

The American Standard H20ption Dual Flush Toilet is an excellent choice if you are looking for a toilet that is easy to use or that is great for long legs. Because of its round front design, this unit is also an excellent choice for spaces with a smaller footprint. Too much of it leads to the flush mechanism being overworked, and it slows the flush down to the point where it barely drains.

American Standard intends to use as little water as possible within this option to ensure that the flush is as forceful as possible. In addition, this option is even more affordable than what we have seen before. It starts at a very low price point. This toilet allows you to choose whether to flush your toilet fully or partially in an effort to ensure that you are using the lowest amount of water.

American Standard Siphonic – Dual Flush Right Height Toilet


Dual Flush Right Height Toilet

The next in the list is also from the American Standard company. With the H20ption by American Standard, the seat is 17.5 inches tall and gets the same technology to select the appropriate number of gallons per flush to maximize the water savings so that there are no wasted gallons. It is slightly heavy from the above toilet but good in performance.

The H2Option system is equipped with a dual-flush actuator that allows liquids to be flushed at a rate of 1 gallon per flush and solids to be flushed at a rate of 1.6 gallons per flush. As a result of the two-button operation of the tank, you are able to select a flush volume that will save you up to 1.6 gallons of water annually when flushing liquids and 1.0 gallons when flushing solids.

Providing a dual flush siphonic right-height elongated toilet with a white, bone or linen color option, American Standard’s H2Option siphonic dual-flush right-height elongated toilet helps you conserve water without sacrificing style or design. The H2Option is able to reduce the volume of water used by 25% when compared with conventional 1.6 gallons per flush single-flush toilets.

A powerful siphonic action with H2Option’s design also led it to be given one of the highest MaP (Maximum Performance) rating and enabling it to handle 1,000 grams of solid waste in a single “heavy” flush while receiving an impressive rating of 400 grams in a “light” flush. The H2Option toilet offers dependable one-flush performance which means you can put your trust in it every time.

A pressurized rim is one of the key features of H2Option toilets. From the tank, water enters the rim chamber, allowing air to be trapped and then pressured inside the chamber due to trapped air. In order to thoroughly clean and powerfully wash the bowl, pressurized water is discharged from a series of specially designed holes on the rim of the toilet.

H2Option makes use of a jetted siphonic bowl which initiates a siphon through the push of the jet while the pull of the siphon evacuates the contents of the bowl. With this configuration, the jetted siphon initiates a siphon through the push of the jet. Water level is also maintained throughout the entire flush due to the siphon-jet action, allowing a cleaner flush and bowl.

In the H2Options toilet line, American Standard has developed a speed connect system that drastically reduces installation time by 30 percent thanks to its user-friendly interface. A pre assembled steel grommet and bolt assembly is used to reduce the installation time and eliminate loose parts by using pre assembled and factory-installed parts.

Buying Guide For Best Dual Flush Toilets

The dual-flush toilet might be an option you want to consider for your new toilet if you plan on installing one in your home. Dual flush toilets are available in different capacities and also there are different factors to consider. You may be looking for the best dual flush toilet kit for many reasons beyond pure aesthetics and luxury. There is nothing worse than having smelly sewage water splashing back up from your single-flush toilet after being flushed.

  • GPF

GPF stands for Gallons per Flush. Dual-flush toilets are usually rated according to the GPF. A toilet’s water conservation rating is based on this number. A dual flush toilet needs less than 1.6 gallons of water per flush which is considered standard. A toilet with a lower number is more energy efficient. WaterSense standards require toilets to use 20 percent less water than the federal standard which is 1.6 gallons per flush, in order to meet these standards.

  • Flushing Power

There are a lot of factors that may contribute to how well a toilet actually flushes including the flush valve, trapway and the plumbing system itself. There are two main types of toilet flushing systems: gravity-assisted and siphonic. The right design makes them very efficient, and they are also very easy to repair. The dual-flush or single-flush models of these toilets are also cheaper.

The flushing power of a toilet will also be increased by a larger toilet flush valve. It is generally accepted that the standard trapway diameter is 2 inches, which is in line with most trapways in general. There can be up to 2 3/8 inch diameter trapways that carry the waste and water out to the drainpipe.

  • Style & Design

Dual-flush toilets are still priced at a premium contrary to the fact that the gap has narrowed as more and more manufacturers have entered the market. So it is important to take your style into account first, as it can often have a combination of direct and indirect effects on the price of a car.

An older bathroom will be a lot easier to upgrade with the addition of the one-piece toilet since it’s easier to clean. It is important to note that these toilets cost more than two-piece toilets. As well as the positioning of the trip lever, the flushing mechanism is also part of the design, and most have this mechanism positioned on top of the toilet.

  • Bowl Shape

If the height of a toilet is set to a comfortable height, the shape of the bowl of the toilet itself can also be considered to make it more comfortable to use the commode. A round bowl is 2 inches shorter than an elongated toilet which has an oval shape. You may already have a round toilet in your home, which is considered to be a “standard” model. Their compact size, ease of installation, and reduced cost make them an excellent choice for smaller bathrooms.

  • Water efficiency

When choosing a dual-flush toilet, it is also important to take this into consideration. There is a reduction in water use when using dual flush toilets over traditional toilets. A major benefit of these products is that they are environmentally friendly as well as helping to conserve water.

  • Flushing power

A dual flush toilet must also take this into consideration when selecting it. One button flushes solid wastes, and another flushes liquid wastes. You can control how much water is used per flush, which can lead to water savings. It is important to consider your budget and requirements when selecting a dual flush system. The right choice may not be for everyone, but they can be great for many homeowners.

  • Price

Because dual flush toilets can cost from hundreds to thousands of dollars, they should fit within your budget. When it comes to picking a toilet, it is very important to consider the cost. The water bill can be reduced by using dual flush toilets even if they are more expensive than traditional toilets.
