Buyer’s Guide for No Clog Toilets

When looking for the best toilets that don’t clog online or even offline stores, it helps to know what features to check out. In this guide, we cover a few of these critical features that will help you in finding a toilet that will not cause a clog. They include:

1. Flushing System 

When a toilet is equipped with a proper flushing system or technology, waste can easily flow out of the toilet into your sewer line. Therefore, it’s important to know what toilet flushing system is best for preventing clogs. Non-clog toilets can be designed with either pressure-assisted flushing or gravity systems. 

Toilets that use gravity flush systems effectively push the waste through the toilet bowl and into the sewer line. On the other hand, pressure-assisted flushing systems use compressed air to help push the water out of the tank and into the toilet bowl faster, resulting in a much faster flush. No wonder these toilets generally flush faster than the ones that use a normal flush system.

2. Trapway Size

Size of the flush valve and the toilet’s trapway matter a lot, as well. The size of the toilet’s flush valve and trapway determines how much liquid and solid waste can be pushed out of the toilet and into the sewer pipe. If your toilet has a trapway that is larger than usual, it will allow water to flow much more easily. That, in turn, means that the chance of your toilet clogging is much lower. 

The same is true for the size of the flush valve. Flush valves are available in a number of sizes and typically range from 2 to 4 inches in size. The faster water is delivered to the toilet bowl, the less likely it is that the toilet will clog. This is why 3- and 4-inch flush valves are especially effective at preventing toilets from becoming clogged.

3. Materials

The material your toilet is made of may not be as vital as other factors, but it can affect its ability to cause a blockage. Today, a majority of toilets are made of ceramic, which is just a mix of silica and abrasive clay. Moreover, some toilets have trapways covered in a white enamel, which gives them a sleek, even appearance that allows water and waste to flow smoothly into your sewer line. The result of this design is improved clog prevention.

4. Water Re-fill Time

You want to flush your toilet after each use to remove all the waste and refill it with clean water as quickly as possible. Toilet models that flush slowly and need to refill immediately are more likely to cause problems due to too little pressure when the flushing mechanism is activated. For example, toilets that take longer than 3 minutes to refill could be a cause for clogs, and an upgrade may be worth considering. Toilets that do not clog should be able to refill in about 1.5 to 2 minutes.

Causes Of Toilet Clogs

Now, let’s talk about toilet clogs in detail. What causes toilets to become clogged? How can they be prevented? Some homeowners or even managers of commercial buildings just don’t know enough to determine when a toilet might clog. 

Below are some common causes of toilet clogs and what to do to prevent this from happening:

1. Low-flow Toilets

These are old-generation toilets that were manufactured before the introduction of more powerful toilets in 1996. Low-flow toilets or older toilet models don’t always offer a more powerful flush because they are designed to help you save water. Many of these toilets have been replaced with newer toilets that offer better flushing capability to prevent toilet clogs. Even if you purchased a low-flow toilet from 1992 (when it first hit the market) to 1996 (when it was properly upgraded), it might not have the best non-clogging feature.

2. Too Much Toilet Paper

Using too much toilet paper when you visit the toilet is another cause of toilet clogs. You can avoid this by reducing the amount of toilet paper you use for each flush or by using a toilet paper roll that has a one-ply design. 

3. Blocked Traps

If the trapway in the toilet becomes blocked, any time you flush the toilet, it will cause the toilet to clog. This is because the trapway is a pipe that catches sewer gas that is escaping through the toilet and moves it out of the sewer line. Too much toilet paper that is too large to be flushed can cause a trapway to become blocked.

4. Foreign Objects

Any time you flush a clog-causing substance or object down your toilet, you’re likely to cause it to clog again. Putting any non-biodegradable material down the toilet, such as sanitary towels, is guaranteed to cause a clog.

FAQs

How do non-clogging toilet models function?

Non-clogging toilets are designed with a larger, wider flush valve and a larger pipe leading from your toilet to your sewer line to make it possible to move more water and waste faster. They are perfect for homeowners who are looking for units that won’t cost them more in plumbing needs due to regular repairs and maintenance expenses.

Why does my kid keep clogging the toilet?

Foods that contain very little fiber can cause children to become constipated. Consuming less than optimal fluids and excessively consuming dairy products can also constipate your child’s digestion system. In addition, changes in routine such as stressful situations, traveling to new locations, and hot weather, may also result in digestive issues, leading to clogging the toilet every time the kid visits the toilet.

What are the best solutions for unclogging a blocked toilet?

Here are a few easy ways to unclog a blocked toilet:

  • Drano max gel drain clog remover.
  • Liquid plum clog destroyer 
  • Hair clog eliminator
  • Drain cleaner that is capable of cleaning your drains by using enzymes or bio cleaners.

How do I unclog a toilet without a plunger?

You should put some baking soda in your toilet bowl and add very little vinegar to prevent it from overflowing. The mixture should start to bubble and fizz immediately. If you use vinegar and baking soda, let the liquid work for about 20 minutes, and then flush the toilet.

Why do some toilet models clog?

Some of the most common reasons certain toilet models clog include flushing down foreign objects such as diapers or sanitary towels. Much old toilet designs with low flow mechanisms are also prone to clogging. Flushing too much toilet paper down your toilet drain can also cause blockages, even if you have a modern toilet design in your bathroom. 

Interestingly, American bathrooms have a different type of plumbing than other countries; it’s narrower. This is why America’s older toilet designs are so easy to clog. Therefore, you need to invest in a good quality modern toilet.
