Why Toilets Clog

Toilets are ubiquitous in modern households, serving as indispensable fixtures for maintaining hygiene and sanitation. However, they are not immune to the issue of clogs, which can quickly turn a routine necessity into a frustrating problem. Understanding how toilets clog is the first step in addressing this issue.

Hydraulic Resistance

Toilets are designed to use the power of water to swiftly and effectively remove waste. When you flush, a significant amount of water rushes into the bowl, creating a force that pushes waste through the drain and into the sewage system. However, any obstruction in this pathway can create hydraulic resistance, impeding the flow and leading to a clog.

Narrow Trapways

The trapway, a key component of a toilet’s design, is the S-shaped section located at the base of the toilet bowl. It is responsible for transporting waste from the bowl to the drainpipe. Many traditional toilets have narrow trapways that can easily become congested, especially when confronted with larger waste or excessive toilet paper.

The Role of Gravity

Gravity is the toilet’s ally, aiding in the transportation of waste. However, if an object or a clump of toilet paper is too large to be carried by gravity alone, it can become stuck in the trapway or bend, thus leading to a clog.

Understanding the science behind toilet clogs is essential for taking proactive measures to prevent them. In the next sections, we will explore 5 best non clogging toilets designed to minimize these issues.

What to consider while Buying Non Clogging Toilet 

Due to the availability of several non clogging toilets on the market, picking out the best non clogging toilet for yourself might seem pretty challenging. Hence, make sure to consider the following factors when purchasing the best non clogging toilet.

Clog free Performance

Clog-free performance is the most crucial feature that you should be considering while purchasing the best non-clogging toilet. Clog-free performance depends on numerous elements such as the size of the trap way, flushing system, flush valve, and toilet design. Read on to find out about ideal specifications that make a toilet the best no-clog toilet.

Flushing System

There’s no denying, the flushing system of a toilet plays the most important role in potentially reducing the chances of clogging. There are 2 distinct types of flushing systems known as gravity-assisted systems, also known as siphon jet, and pressure-assisted systems.

Gravity flush systems mainly use the force of gravity along with water weight to push down the mass of waste into your sewer line. On the other hand, pressure-assisted systems make use of compressed air to push down the water along with waste into the sewer line.

Surprisingly, pressure-assisted systems have proven to work more efficiently as compared to gravity-flushing systems.

Larger Trapway

The size of the trap way is important as it regulates the amount of liquid and solid waste leaving your toilet bowl. Generally, when a toilet’s trap way is large it allows smooth and maximum flow of waste materials into the sewer lines, which results in significantly reduced chances of clogging.

Flush Valve

Likewise, the trapway, the size of a flush valve plays an equally important role in determining the clog-free capabilities of a toilet. Typically, flush valves come in a variety of sizes that range from 2-4 inches. The faster the water is delivered to the bowl, the faster the waste elimination process takes place.

Hence, larger flush valves have an advantage over smaller flush valves when it comes to reducing clogs.

Toilet Design (One Piece or Two Piece)

The two most common toilet designs are one piece and two piece toilets. As the name suggests, in one piece toilets both the bowl and flushing tank are combined in one unit. On the other hand, in a two-piece toilet, the tank and bowl serve as two independent components.

When it comes to clog-free performance, one-piece toilet has managed to stay one step ahead as it supports the anti-clogging features of a toilet by providing a larger trap way to eliminate waste.

What are the Common Causes of Toilet Clogs

Toilets are subjected to a variety of waste materials, and understanding the common culprits behind toilet clogs is crucial in preventing and mitigating this inconvenience.

Toilet Paper Overload

The primary suspect in many toilet clogs is an excessive amount of toilet paper. While toilet paper is designed to disintegrate when wet, the excessive use of it in a single flush can overwhelm the toilet’s capacity to break it down. This leads to blockages, especially in toilets with narrow trapways.

Foreign Objects

Children’s toys to personal items, can unintentionally find their way into the toilet. These objects are not designed to be flushed and can easily become lodged in the trapway.

Excessive Waste

Toilets are meant to handle human waste, but when excessive waste is flushed, it can quickly overwhelm the system. The trapway and the drainpipe are not designed to accommodate excessive loads of waste, leading to clogs.

Lack of Maintenance

Neglecting regular toilet maintenance, such as cleaning and addressing minor issues, can contribute to clogs. Over time, mineral deposits and debris can accumulate in the trapway, reducing its efficiency.

Older Plumbing Systems

In some cases, older plumbing systems may have narrower drainpipes, making them more susceptible to clogs. The design of these systems may not be conducive to efficiently handling the volume and types of waste produced by modern households.
