How To Find Best Toilet For Flushing Large Waste- The Buying Guide

There are different factors to consider before choosing a toilet for flushing large waste. The first thing is to consider the type of toilet for your bathroom.

Different Types of Toilet Flush Systems

Here are eight different types of flush systems found in the modern flushing toilets, each of which has various advantages to offer

Gravity flush system

Being the most common type of flush system, this one uses gravity to flush the toilet. Most of the other flushing systems borrow the main idea from the gravity flush system. When the flush button is pushed, the water flows from the tank and moves to the bowl through gravity. A force is created inside the bowl, which makes the toilet trap to remove the waste.

Tower Style Flush System

It is used mostly in Kohler’s flushing toilets and is also known as a canister flush. In this kind of flush system, a canister flapper is used that is connected to the flush handle and mounted in the middle of the tank. The flapper is lifted off completely when the handle is pulled, allowing the water to enter from a 360-degree angle. This angle lets the water enter the bowl faster and creates a strong flush to provide better flushing and cleaning operation.

Pressure-assisted flush system

The pressure-assisted flush system combines air pressure with the gravity flush system. When the flush button is pressed, the water leaves the tank and powerfully flushes the toilet due to the presence of air pressure from the second tank present inside the main tank. This flush system is a lot louder than the gravity flush system.

Pressure-assist or gravity — which should you choose? See our full Pressure Assist Toilet vs Gravity comparison.

Double vortex flush system

This kind of flush system is usually used in gravity flush toilets by American Standard. There are two nozzles mounted on top of the bowl in this flush system, and most of the water enters the bowl through them. However, this is not it as some amount of water simultaneously enters the trap way with the vortex action. This result creates a more powerful flush to make flushing larger waste easy.

Dual flush toilet system

The dual flush toilet system has two flushing buttons mounted on the top of the lid of the tank. This allows the user to have two options for the amount of water. One button allows less water flow, usually for liquids, and the other one allows more water to be used for solid waste. There is a dual flush valve assembly present inside the tank. When any of the two flush buttons are pressed, the seal on the valve lifts and allows the water to move down to the bowl.

Single flush system

The single flush system doesn’t give you the option of two water amounts as you can only use the same amount for flushing solids and liquids. Usually, the toilet tank has a lever handle mounted on its side for flushing purposes which is connected to a lift chain. The lift chain is connected to a flapper, so when you pull the handle, the chain lifts the flapper off and allows the water to move down to the bowl.

Double Cyclone flush system

This was TOTO’s previous-generation flush system, now replaced by Tornado Flush on current models. Two nozzles faced sideways at the top of the bowl, and this is where the water enters the bowl from. As a result, the water has a movement like a cyclone inside the bowl, which is excellent for cleaning, rinsing, and flushing the toilet.

Tornado flush system

It is an improved version of the Double cyclone flush system, which was also designed by TOTO. In this kind of flush system, two nozzles are placed under the rim, facing sideways. Therefore, when the button is pressed, and the water enters the toilet, it keeps swirling around like a tornado. This tornado movement effectively cleans the flushing toilet and provides a quieter operation.

Here are the factors that you need to look for before making the final purchase.

Toilet Shape

The toilet comes in two shapes, including an elongated and the round one. Since the elongated flushing toilets are slightly longer than the round ones, they are more comfortable and are now widely considered by people.

Toilet Height

Taller flushing toilets are usually more comfortable to sit on and cause fewer backaches. If you have had backache problems sitting on short toilet seats, getting a 17 to 19 inches tall toilet seat is the best option. However, these may not be the best options for small children; therefore, the standard height of 15 inches will also do the job well.

Toilet Size

You don’t want to increase your hassle by buying a toilet that doesn’t fit in its space. Therefore, it is extremely important to take all the necessary measurements of the toilet in order to go well with the size of your bathroom. The correct dimensions of the toilet’s height, width, and depth should be taken so that it fits in the space provided in your bathroom correctly.

Budget

The price of each toilet is different, and the one that suits you the best depends entirely on your budget. The toilets that are available at lesser prices may work fine but lack additional features like longevity, durability, etc. The toilets available at higher prices have some exceptional features in-store, including excellent flush systems, heated seats, technology specifically designed to keep the bowl and toilet seat clean, etc. All of these features are definitely worth paying the extra amount.

Toilet Seat

The toilet seat plays an essential part in providing a comfortable sitting arrangement; however, it is not always included with the toilet. Most of the high-end flushing toilets have heated toilet seats or have cleansing attachments. However, for toilets that do not have seats, you can easily upgrade them at any time.

WaterSense feature

The flushing toilets that have been certified by WaterSense are great to go for. A WaterSense certification means that the toilet has been approved to work as a water-efficient product. This is essential for saving water no matter how many times you use the flush feature of your toilet.

GPF (Gallon per Flush)

Standard gallons per flush (GPF) is 1.6, but there have now been hundreds of models designed that use lesser water, around 1.28 GPF. If you are pretty conscious about saving water, then going for the lesser GPF is always a great option.

Flush Strength

There is no point in having a toilet that saves water but requires you to flush it multiple times. Therefore, getting a toilet that has strong flushing power is essential. The dual flush system is quite efficient in saving water and preventing clogs to a significant level.

Toilet Appearance

Having a toilet that doesn’t go well with the theme of your bathroom will look odd. This is why you need to pay attention to the looks too. Toilets are now available in various colors, sizes, and styles, which can match your needs without any hassle. All you need to do is to have proper research before making your final decision.

Noise levels

There is no denying that flushing toilets make noise when you flush them. Look for models that advertise a quiet flush option since you will not want to embarrass yourself with the loud noise of flush every time you use your bathroom.

Conclusion

Buying the right type of toilet has not been much of a concern for people; however, it should be to get the best out of it. Imagine getting a toilet that doesn’t flush properly, and you have to waste your time and energy to make large waste vanish. To avoid this from happening, having toilets that can easily flush out large waste with their exceptional flushing power is extremely important. While most the toilets may claim this feature but still it is essential to ensure powerful flushing system of toilet to get rid of large waste.

• EPA WaterSense
• MaP Testing (Maximum Performance)

Plumber’s field tip: when a toilet ‘can’t handle’ large waste, the trapway is usually fine — the flush is starved. A worn flapper that drops early, or a fill valve set below the waterline mark, cuts the flush short. Before replacing the toilet, check the tank water sits at the marked line and the flapper stays up until the tank empties. Fix the cheap parts first; if it still chokes on normal use, then shop for the 2-inch-plus trapway.

Frequently Asked Questions

What trapway size is best for flushing large waste?

Look for a fully glazed trapway of at least 2 inches; 2-1/8 to 2-3/8 inches is the sweet spot on modern high-performance toilets. The glaze matters as much as the width — an unglazed patch inside the trap is where waste catches and builds up over time.

What MaP score do I need for large waste?

MaP testing measures how many grams of waste a toilet clears in one flush. For reliable large-waste flushing, choose a toilet rated at 800 grams or more; 1,000 grams is the maximum score and is what the strongest pressure-assist and high-performance gravity models achieve.

Is pressure-assist better than gravity for large waste?

For sheer clearing force, yes — a pressure-assist vessel fires water through the bowl faster than gravity alone, so bulk waste is less likely to stall. The trade-offs are noise and a harder flush sound. A good gravity toilet with a 3-inch flush valve and a wide trapway comes close and runs much quieter.

What is the standard toilet seat height?

A standard toilet’s seat sits about 15 to 16 inches off the floor. Comfort height models raise that to 17 to 19 inches, which most adults find easier for sitting and standing — and the taller bowl also gives waste a slightly straighter drop into the trapway.

Why does my toilet flush weakly even though it is not clogged?

Usually the tank, not the bowl: a water level set below the mark, a flapper that drops too early, or scale clogging the rim jets all starve the flush. Correct the water level, replace a tired flapper, and clear the rim jets before blaming the toilet itself.
