Things to Consider
A toilet is an essential product in your house. It turns your restroom moments into an exciting ritual. While the price and color matter, the amount of water it uses, and how effectively it flushes waste matter more. That’s why having the best dual flush toilet is paramount. It generates adequate power to clean the bowl and conserves water at the same time. This guide will enable you to choose an excellent dunny that will suit your bathroom needs and budget.
Why dual flush toilet is a must-have
The dual flush toilets have become popular, and they’re a green addition to homeowners. A dual flush toilet is designed with a water-saving mechanism that is considered environmentally friendly. Whether you’re renovating an office, or building a new home, or remodeling an outdated bathroom, it’s crucial to understand why having a dual flush toilet is the smartest decision you can make.
So, why is a dual flush toilet a must-have? This type of toilet has some benefits, such as:
Environmentally Friendly – A dual flush toilet bears the name due to the dual flushing mechanism. The two-setting system is usually a lever like KOHLER 3989-RA-0 Highline, or a button on the toilet like American Standard 2886518.020 H2, to allow either high or low volume flush. The high-volume flush is engineered for solid waste, while the low volume flush is for liquid waste. Therefore, a dual flush toilet allows the conservation of water. Most of these models comply with the NEP guidelines of not using more than 1.6 gallons per flush. This is compared to conventional toilets, which utilizes more than 3.5 gallons per flush.
Simple Maintenance – Dual flush toilets are designed to utilize gravity in disposing of waste down the trapway. The design minimizes down leaking and clogging and saves you the hustle of undesirable plunging expedition. The powerful flushing mechanism is sufficient such that you don’t need to clean the toilet after every use.
Cost Savings – This is one of the reasons you should have a dual flush toilet. A dual flush toilet can help a family of four to save approximately 13,000 gallons per year. According to the EPA, dual flush toilets can help in conserving about 20% water usage. More so, it can save a homeowner approximately $100 annually. In short, a dual flush toilet gives you a clean bathroom with less water, and leave more bucks in your pocket.
Dual flush anatomy – simple explanation
The way water flushes out waste from a bowl will determine the amount of water required to get the job done. Conventional toilets are designed to use siphoning action to evacuate waste. This means a high amount of water will enter the bowl when flushing.
However, the dual flush toilets use a larger trapway and an effective wash-down flushing design. It quickly pushes the waste down under a low volume of water. The system applies two mechanisms to get rid of waste. The liquid waste requires less water, while the solid waste may need more water for evacuation. But even for the solid waste, a reliable dual flush toilet does not consume more than 1.6 gpf.

How to Choose Your Toilet Type
When it comes to choosing a toilet, price, design, and the material used is not the only crucial factors to consider. There are a couple of things you need to deal with. Dual flush toilets come in different styles.
One-Piece Toilets – These types of toilets are compact. So, if you want some space-savings models, then go for 1-piece. The products sit lower near the ground, but the seat height offers some comfort, especially to the seniors. When choosing this type of toilet, check the seat height for kids, aged people, and grown-ups. For these models, vital parts are protected from harm. Hence, they last long. In 1-piece toilets, crannies and nooks are eliminated so you can freely clean the product hassle-free. More so, there are a few places where microbes accumulate and grow, making the seat safe.
Two-Piece Toilets – The two-piece toilet models have been around for a longer time than 1-piece models. These types of toiles cost less and use less effort to flush. In this model, the tank and bowl are separate and fused. They are more efficient and better at conserving water.
Wall-Hung Toilet – This model brings a contemporary look to your bathroom. The detached carrier tank is mounted on the wall.
As you’re choosing your toilet, select the model that will meet your needs. More so, consider your home and bathroom décor and people around. For the elderly and kids, ensure the height is convenient.
You can get a cheap toilet for less than $100. However, don’t expect a cheap dual flush toilet with a powerful flush mechanism. When it comes to these types of toilets, you get what you pay for. Your toilet is a vital room in the house. It means you’ll use it every day for years. Therefore, get a high-quality model. For a gravity toilet, plan to spend approximately $500. For a pressure-assist model, you’ll spend between $300 to $600.
Features to Consider While Buying the Best Dual Flush Toilet
Securing the right dual flush toilet can be a complicated process. Apart from several models on the market, there is a myriad of features to consider as you pick your item. Below, we’ve highlighted essential factors you should pay attention to. They’re meant to make the entire process seamless and exciting.
Dual flush toilets are trendy and highly effective. Their design is to use lower water consumption. According to the Environmental Protection Agency, a consumer can save at $100 on water bills per year by using a dual flush toilet. With these models, you can choose between a full flush and a partial flush.
The partial button is for eliminating liquid waste, which can use between 0.8 to 1.1 gallons of water. The full flush flushes solid wasted at 1.6 gallons. The EPA estimates that an average person can use 40% less water in a day than someone using a standard low-flow toilet.
Some of the older models use between 3.5 gpf to 7 gpf. That’s why you need a dual flush toilet. Though a bit expensive, it’s worth every penny.
As you choose your toilet, ensure it uses less than 1.6 gallons per flush. This will help you conserve water and minimize your water bills drastically.
In this case, Swiss Madison SM-WT450 is the best water-conserving dual flush toilet in the market. Thanks to its design with water consumption of 0.8 gpf for partial flush and 1.28 gpf for full flush.
A toilet is an essential piece in every home. They have evolved over time, not only on conserving water but also in transforming the bathroom spaces. Dual flush toilets come in various shapes and sizes. The bowl shape should be a consideration. There are different bowl types such as;
Wall hung – Wall hung, or wall-mounted toilets are mounted to the wall. This means they don’t have the extra pedestal or the external tank. The sleek design will make the restroom a great room to be in. The entire plumping and piping work is done directly on the wall behind a bowl. If you’re looking for the best wall-hung dual flush toilet, Swiss Madison SM-WT450 is the right pick.
Close-coupled – Close coupled is the most common type of toilet. The cistern and bowl are joined into a single piece. The design ensures there are no external plumbing leakages.
Bowl on the floor – This is where the toilet is fixed on the floor. The water closet and pipes are both concealed behind the wall. If you want to save the space, this is the perfect bowl type to choose from.
After choosing your preferred bowl type, you can now decide the shape that you want. Bowls come in various configurations.
Round toilets are no longer appealing. They have been replaced by elongated ones such as TOTO Aquia IV. Elongated seats are ADA-compliant and suitable for personal or guests use. More so, they’re larger than the round counterparts. However, these models are not ideal for small spaces.
Typically, round seats are 3-6 inches smaller than regular elongated ones. They can also be fitted ion kids’ bathroom. If the bathroom space permits, always choose elongated seats.
Skirted or not?
Skirted toilets are designed with a smooth and elongated appearance. The construction of such toilets conceals the trapway that provides a base that’s easy to clean. These models offer clean lines and minimal crevices and flourishes. The geometric precision will give your bathroom an upscale appearance.
You’ll appreciate the clean lines of the skirted dual flush toilet while doing the cleaning routine. Skirted toilets are typically aesthetic options that come with rounded and straight edges for comfort. The removal and concealing of ugly pipes leave you with a sleek-looking dual flush toilet.
Therefore, a skirted toilet is suitable if you want to make your cleaning and maintenance routine seamless.
When a company offers guarantees on their products, it sends a message that they have complete trust in their items. As a consumer, a warranty provides you an added protection if something goes wrong. Some warranties go an extra mile of covering the accidental damages during shipping.
As you shop for the best dual flush toilet, choose a product that comes with a warranty. Some manufacturers offer different warranties for the same product. For instance, WOODBRIDGE T-0019 comes with a 5-year limited warranty on porcelain parts and 1-year limited on flushing mechanism and components.
Toilet certification is crucial. For any manufacturer to have a WaterSense label on their label, it means they have an agreement with EPA to ensure the products conform to the relevant specifications.
It can be easy to choose a bowl that appeals to your eyes. But have you thought of checking the material used for construction? The fabric used also plays a crucial role in the durability of any product. And when it comes to toilets, it’s no exception.
Most toilets are made of Vitreous China or porcelain. There are also ceramic toilets, though not widespread. Porcelain has proved to be reliable and durable. And from the production point, it’s cheap. Therefore, a dual flush toilet made from porcelain is durable, sleek, and inexpensive. The material also comes in different colors like peach, green, white, and glacier blue.
Toilet seats are made of genuine wood, cushioned vinyl, plastic, and polypropylene. And each material affects the price of the product.
Generally, a porcelain toilet is ideal since it’s both durable and cheap, a rare combination.
Dual flush toilets come in different sizes. And as you go for a sleek look, it’s essential to check if it will fit in your bathroom. Get the right dimensions by measuring the seat heat, width, depth, and the overall height of the toilet.
There should be at least 25 inches of space for the toilet in the restroom, no matter where it’s being placed. For small spaces, choose compact models such as Swiss Madison SM-WT450. The standard measurement is roughly 27-30-inch deep, 28-33-inch high, and 20-inch wide. If you don’t have an idea of what will suit your bathroom, get help from a professional.
Easy installation and rough-in size
Your first assignment when picking a dual flush toilet is to measure the rough-in size. This is the distance between the middles of the dunny and the wall. A precise measurement of rough-in prevents you from returning the product or making unnecessary adjustments.
The standard size is about 12 inches. However, most designs can accommodate between 11-13 inches. You can also install a toilet with a smaller rough-in, but it will leave a gap between the wall and the toilet.
When it comes to installation, most products come with an instruction manual. This is to help you follow a step-by-step guide for installation. But everyone who can hack into this. In this case, get help from a professional plumber.
Operation and convenience
A dual flush toilet gives you an option to pick between a complete or fractional flush. The complete or full flush will utilize a higher amount of water per flush. But it’s effective in cleaning solid waste. The fractional flush uses few gallons per flush and suitable for liquid waste.
If you have smaller kids or seniors in your house, your choice should accommodate them. Flush performance is essential. Whether you have a pressure-assisted, option, a compact toilet, or a gravity-based bunny, an excellent flushing technology is imperative.
Other extra features include aesthetics. An excellent purchase is not just about the price or cleaning method. You also need a toilet that will complement your bathroom décor and accentuate your individual style.
More so, check the brand. A reliable manufacturer will give you’re a durable product. Read more reviews online about the specific brand. Get the views about the product from previous clients.
How much can a toilet accommodate? This will be indicated on the label. An ideal dual flush toilet should be able to support 500 lbs. This weight capacity can accommodate most people, from kids to plus size.
Loo maintenance isn’t one of the favorite chores on anyone’s to-do list, but it’s essential. The modern dual flush toilets are eco-friendly and save tons of water. However, they need regular maintenance for long-lasting services.
If there is a leak on the floor, tighten the water pipe connections. Also, ensure the big plastic nut fitted at the pipe beneath is tight. When the toilet doesn’t flush, check inside the cistern and the flushing arm to ensure it’s working correctly.
Poor flushing can be due to the flush pipe being too tight to allow water flow. A loose handle can also lead to flush failure. Ensure you perform maintenance routine often. If not, ask for help from a professional.
A dual flush toilet is designed with two flushing modes; partial flush and full flush. If you press the partial flush button, a low amount of water will flow into the bowl. This is ideal for liquid waste. The full-flush button is for solid waste. If the small button doesn’t clear the waste in the bowl, you can press the larger button for more water.
Pressing both buttons will give more water. However, this will not be ideal since the idea behind a dual flush toilet is to save more water.
Yes, they are. And here is why. The dual flush toilet is intended to use gravity to evacuate waste through the larger diameter trapway. This prevents clogging. More so, it needs less water to evacuate waste.
