Buyers Guide

We hope that you have made a note of the best toilets that do not clog. The next step is to keep the following features in mind while comparing the top no clog toilets that fit your budget and requirement.

 

 

Flush Valve and Trapway Size

The most crucial specifications that you need to check in the no clog toilets are the diameter of the flush valve and the trapway size. The diameter of the flush valve will determine the force with the water will gush out of the tank to force out solid waste and a large trapway will allow the waste to easily pass from the bowl into the sewage pipes. The best toilets that do not clog usually will have a 3-4 inches wide flush valve. The toilets should have at least a 2-1/8 inch wide trapway to ensure clog-free operation.

 

 

Flushing System

A weak flush is a primary cause of clogging. Therefore, you must choose clog proof toilets that ensure a powerful flushing mechanism. Ideally, the pressure-assisted toilets make for the best toilets that do not clog. They use the force of compressed air to push out waste in a single flush that too by using considerably lesser water.  Even though their strong flushing mechanism generates a lot of noise, they are best suited for commercial use or for households that have multiple users. However, today you can also find powerful gravity-fed toilets that can keep up with the effectiveness of a pressure-assist toilet and are also quieter than their counterparts; the perfect example of which would be the TOTO Drake model.

 

 

Water Consumption

Not only should the best no clog toilets be able to take care of your waste, but they should also be able to cut down your water bills. Most of the toilets today use 1.6 GPF but you can also find models that consume 1.28 GPF or less, making them 20% more water-efficient than the 1.6 GPF variants. Additionally, you can also opt for dual flush toilets that consume 1 GPF or less for liquid waste. The WoodBridge T-0001 is an excellent choice in the dual flush category.

 

 

Cleaning

One-piece models are easier to clean as they do not have too many joints compared to the two-piece toilets. Plus, toilets with a skirted trapway also make them easier to wipe clean. In addition to that, the best no clog toilets also come with a glazed coating that does not let dirt and grime adhere to the surface of the toilet. E.g. the CeFiONtect glaze by TOTO or the EverClean surface by American Standard. Toilets made of vitreous china with a fully glazed trapway are also easy to keep clean.

 

 

Noise Level

Pressure-assist toilets that do not clog can be quite loud and disturbing especially when using the toilet in the wee hours. If noise is an issue, gravity-fed toilets are much quieter and can still mitigate clogging with their advanced engineering. Plus, toilet seats can also make loud slamming noise, so go for the ones that include a soft-closing seat or you can also purchase a SoftClose seat separately if a seat is not included in the package.

 

 

Seat Height

Toilets come with a standard height (15 inches) or Comfort Height (17-19 inches). Standard height models are ideal for families that have members of all ages. Comfort Height offers great comfort to tall individuals, elders, or people with disabilities.

 

 

Installation

Two-piece toilets that do not clog are much easier to install as their tank and bowl can be handled separately. One-piece toilets are heavier units and require extra hands to maneuver the body from one place to another. Plus, you must keep the rough-in measurement in mind as you want the toilet to fit into your bathroom. Most of the no clog toilets come with a standard 12-inch rough-in measurement.

 

 

Warranty

Just like any other machine, no clog toilets also are prone to wear and tear with regular use. Therefore, you must check the warranty cover offered by the manufacturer. Most of the top manufacturers provide at least a 1-year limited warranty on toilets that do not clog. A warranty cover also reflects the trust of the brand in its model. There are models such as the American Standard Champion 4 that comes with a 10-year warranty.

 

 

Brand

Since toilets are expensive fixtures, you must choose a model from a reputed brand rather than going for a plethora of features offered by a new entrant. While there is no harm in going for feature-rich no clog toilets, the older brands are more trustworthy in terms of durability and after-sale service.

 

 

Frequently Asked Questions For Clog Proof Toilets

How do I ensure that the toilet I intend to buy will not have clogging issues?

The only way to ensure that you are bringing a clog-proof toilet is by checking its flush valve and trapway size. Toilets that do not clog have a flush valve larger than the standard 2-inch valve and a trapway larger than 2-1/8 inches. Apart from the technical specifications, another way to make sure that your toilet does not clog is to avoid disposing of certain waste down the toilet such as sanitary pads, dental floss, condoms, etc.

 

 

What flushing mechanism do no clog toilets use?

Top no clog toilets feature different flushing mechanisms that not only ensure clog-free performance but also use lesser water per flush. The most powerful anti-clogging toilets are usually pressure-assisted, but you also have some highly efficient gravity-fed toilets that can give a tough competition to the pressure-assisted ones.

 

 

What causes toilets to clog?

Some of the most common items that tend to clog toilets include thick tissue papers, face wipes, tampons, sanitary pads, and kid’s toys and balls. In case you have kids in the house, do keep a watch on them to prevent them from throwing anything in the toilet. Also, keep the toilet seats closed when not in use to avoid anything falling accidentally in the commode.

 

 

How can I unclog the toilet on my own?

If the clog is in the trapway, it can be tackled on your own with the help of a plunger. To use a plunger, secure the cup of the plunger over the opening of the trapway to create an airtight seal. Then, push and pull the plunger vertically a couple of times. Wait for 20-30 seconds and the water in the bowl should start receding. Repeat a few more times to ensure that no clog debris remains. If this first method doesn’t help, you can make a mix of baking soda and vinegar in the ratio 2:1 and pour it into the toilet. Let it sit for 15-20 minutes, then use the flush. This method can also help you unclog your toilet successfully. However, if the DIYs do not help, it is better to seek professional help as the blockage can be somewhere down the sewage pipes.

 

 

What toilet is best for not clogging?

Though all the toilets listed in our review are no clog toilets, the ultimate winner, as per our research, is the American Standard Champion 4. Its 4-inch is the largest in the market that powers a highly efficient flushing mechanism.

 

 

Conclusion

Everyone agrees that unclogging a toilet is a task that we would want to procrastinate for life. However, if you invest in the best toilets that do not clog, you can bid your plunger adieu for good. There are several options available for budget toilets as well as for the high-end makes. We have tried to list clog proof toilets that suit every pocket and hope that our detailed reviews of the top no clog toilets will help you make a wise choice for next toilet.
