The Buying Guide for No-Clog Toilets
The annoying process of plunging out clogs from your toilet is something you don’t want to experience on a regular basis. Investing in the best non-clogging toilet can help you avoid this embarrassing scenario every few days.
But first, let’s look at some common causes of toilet clogs and how you can avoid them in the first place.
Common Causes of Toilet Clogs
Here are the most common causes of clogs in toilet systems:
1: Low-flow First-generation Toilets
If you still have a toilet system designed in the mid-1990s, it cannot clear the internal trap and drain effectively. These low-flow toilets clog easily and are better off replaced.
If you don’t have adequate money yet to install a new toilet unit, you can minimize clogs by reducing toilet paper use or using highly biodegradable bamboo toilet paper.
2: Blocked Toilet Traps
A toilet trap is a U-shaped pipe that always remains filled with water to prevent foul odors in the sewer line from seeping into the house.
The U-shaped bend in the trap often makes clogging easy. To avoid frequent clogs, be careful with toilet tissue usage and avoid flushing hard objects that can settle in the trap and cause clogs.
3: Flushing Foreign Stuff
Your toilet is designed to flush human waste and soft toilet paper. Flushing foreign objects that are harder than human waste will cause clogging. Things like hard paper, diapers, sanitary pads, and wet wipes are all non-flushable and can clog your toilet.
4: Toilet Paper Usage
If you stuff toilet paper down the u-trap, it will most likely cause a clog. Avoid this by folding used tissue paper instead of rolling it into a ball. You should also reduce the use of toilet paper to a bare minimum.
How Choose the Best Toilets That Don’t Clog
Now, before you pick the best clog-free toilet system, you need to learn about the features to look for before buying one. Understanding the specifications of the toilet unit will ensure that you end up with a perfect porcelain throne. Here are the key features that distinguish exceptional no-clog toilets from regular toilets:
Most toilets are made of ceramic material that is typically a mixture of silica, clay, and a fluxing agent. The difference often lies in the color, shade, and type of finish that covers the toilet. This last aspect will define the general look of the toilet, as well as how easy it is to clean and maintain. How smooth and sleek the outer cover is will also determine how easy waste moves down the toilet to prevent clogs.
2: Flushing Mechanism
Toilets feature different flushing mechanisms depending on the manufacturer. The most common flushing types used on modern no-clog toilets are dual flush and tank-less systems.
A dual flush system allows you to choose what amount of water to use. You will use a light flush for liquids and a heavier flush for solid waste, allowing you to conserve water. With a tank-less system, the cleaning typically depends on the flush pressure since water does not refill the tank.
Flush systems can also be siphonic or wash-down. With a siphonic toilet system, the cleaning process is triggered by the water from the tank. When you press the flush button, the water pushes wastes down and evacuates the bowl content.
A wash-down mechanism, on the other hand, washes down the content of the bowl without evacuating the bowl. Such designs come with a deep bowl with a small water area to ensure that the content is gravitated out of the bowl.
More importantly, choose a toilet system with large flush valves and trapway outlets to guarantee a powerful flush with no clogs.
3: Bowl Types
Although this feature has nothing to do with clogging, choosing the right bowl type will ensure comfort. It’s often a matter of taste and preference. The two most common bowl types are round or elongated.
Round models are more space-saving but can be less comfortable for some users. Elongated bowls are considered more comfortable, but they typically require more floor space. Some manufacturers offer toilets with square bowls, but they are currently not in big demand. You may also consider a low-profile model if you have space constraints in your bathroom.
4: Water Consumption
Studies indicate that almost 30% of water is consumed by residential toilets across the US. To help conserve water, it’s important to choose toilet models that are certified by EPA WaterSense and consume less than 1.6 gallons per flush.
5: Water Refill Time
This feature is vital for any anti-clog toilet. If you pick a model with a tank, ensure that it can fill up fast after a flush. This is particularly important if the toilet is used by multiple people flushing within short intervals.
6: Installation Requirements
Some toilets are simple to install as a DIY project while others require a professional approach. Always consider the complexity of the installation process if you’re planning to install the unit on your own. Alternatively, hire a professional plumber to save you the hassle.
7: Manufacturer Warranty
Like every other household fixture, toilets can fail at the least expected time. You can escape many problems with your toilet by going for one with an extended warranty period. The least period for a manufacturer’s warranty is one year, but a good quality toilet should come with a five-year warranty or more.
8: One-piece or Two-piece?
Last but not least, you can choose between one-piece and two-piece toilet designs. One-piece toilets are becoming increasingly popular as they appear sleek and seamless, which makes them fit any modern bathroom design. They are constructed with fewer joints and seams, so they don’t collect much dirt or moisture.
Two-piece options are still available on the market. Although they have some downsides, such as difficulty in cleaning due to joint crevices, they are often cheaper (depending on the brand) and simpler to install.
