What to Look For When Buying No Clog Toilets
All no clog toilets we have reviewed have been selected with these criteria in mind. We want to make sure you buy once and buy right the first time!
Here are some important things to look for when buying no clog toilets:
Pressure-Assisted Flush
A pressure-assisted flush system is known for its powerful and efficient flushing ability. It uses compressed air to forcefully push water into the bowl, producing a robust flush that clears waste thoroughly. This type of flush is less likely to get clogged and is particularly useful in households with heavy usage.
Minimum 3 Inch Flush Valve
A larger flush valve, such as a 3-inch one, allows more water to enter the bowl quickly. This helps create a strong flush that effectively removes waste without clogging. It’s important to consider toilets with larger flush valves for enhanced flushing performance.
Minimum 2 Inch Glazed Trapway
The trapway is the curved passage inside the toilet bowl that leads to the drain pipe. Check for toilets with a minimum 2-inch glazed trapway, as this smooth, glazed surface prevents waste from sticking and inhibits the buildup of residue, reducing the chances of clogs.
One-Piece Toilets
One-piece toilets have a seamless design with the tank and bowl fused. They often have a sleek and modern appearance, and their one-piece design minimizes potential leak points. This makes them easier to clean and less prone to clogging issues. They are nice to have, but not an absolute necessity.

Guide to Buying Toilets That Don’t Clog
When seeking out the best no-clog toilets, it helps to know what features to look for. In this guide, I’ll go over some of these features to help you take out some of the guesswork when it comes to finding a toilet that will have minimal clogging issues.
Think of a toilet as an investment. And as with any investment, it’s important to know what aspects and features make it worth it.
This is no different for toilets, and below are a few that you should note during your search for the best no-clog toilets.
Flushing System
Hands down, the flushing system of a toilet plays the biggest factor in its ability to reduce potential clogs. The two main toilet flushing systems are gravity (or “siphonic systems“) and pressure-assisted flushing systems.
Gravity flush systems use the weight and pressure of water to push the waste out of the bowl and into your sewer line.
On the other hand, pressure-assisted systems use compressed air to propel the water out of the tank and bowl, which results in a stronger flush. Unsurprisingly, these toilets tend to clog less often than gravity flush systems.
Flush Valve and Trapway Size
The size of the flush valve and trapway is important as they regulate the amount of liquid and solid waste that can flow out of the toilet to the sewer pipes. Typically, when a toilet’s trapway is larger in diameter, it allows for better flow capability, resulting in a reduced likelihood of clogging.
The same holds for the flush valve size. Flush valves come in various sizes and typically range anywhere from 2 to 4 inches. The faster the water is delivered to the bowl, the less likely the toilet is to clog. This gives 3 and 4-inch flush valves an advantage in reducing clogs.
Water Re-fill Time
Overall, you want a toilet to remove waste and re-fill with fresh water as quickly as possible. Toilets that flush and re-fill slowly are more likely to clog from too little pressure when the flushing mechanism is activated.
If your toilet takes over 3 minutes to refill, this could be the cause of clog issues, and an upgrade may be worth considering. Ideally, no plunge toilets will refill in about 1.5 to 2 minutes.
Materials
This may not be as crucial as other factors, but the material that composes a toilet can also play a small part in its clogging capability. Yes, today’s toilets are made of ceramic, a mixture of clay and silica.
However, toilets with trapways covered in enamel create a sleek and smooth surface, which allows water and waste to flow out of them and into your sewer line seamlessly. The result is increased clog prevention. We recommend looking for a glazed trapway to help things slide down smoothly.
Frequently Asked Questions
Are no-clog toilets really clog-proof?
While no-clog toilets are less prone to clogging than traditional toilets, it’s still possible for them to clog under certain conditions. Large items like baby wipes or large amounts of toilet paper can cause a clog. However, no-clog toilets are much more resistant to clogging from normal use.
How can you tell if a toilet is truly no-clog?
Look for “max-flush performance” or descriptions of wide trapways and powerful flush valves. Names like “Champion” or “Pressure Lite” indicate toilets with larger-than-average trapways and pressure-assisted flushing. Brands like American Standard make validated no-clog models.
How is the flush different on a no clog toilet?
No-clog toilets have flush valves or siphonic jet mechanisms that generate more powerful flushes than standard gravity-fed toilets. This additional flush power allows no-clog toilets to flush large waste completely without it getting stuck. The trade-off is that no-clog toilets tend to use slightly more water per flush.
What is the best toilet for not clogging?
The American Standard Champion 4 is the best toilet for not clogging.
Common Causes Of Toilet Clogs
While all clogs can’t be prevented, a few factors and scenarios come into play that increase the likelihood that your toilet will clog.
Low-flow First Generation Toilets
The initial line of low-flow toilets wasn’t necessarily meant to offer a more powerful flush, as they were meant to conserve water. Many of these toilets have since been replaced with new, more powerful toilets that have features conducive to reducing clogs.
So if you purchased a low-flow toilet anywhere from 1992 (when they hit the market) to about 1996, it may not have the best flushing clog-prevent capability.
Toilet Paper Usage
Excessive toilet paper usage is among the most common causes of toilet clogs. You can avoid this by reducing your toilet paper with each flush or purchasing one-ply toilet paper.
Blocked Toilet Traps
If the trap in the toilet is blocked, it’ll create a clog once the toilet is flushed. The trap is a U-shaped pipe that keeps sewer gases from entering the toilet and moving the content from the toilet bowl through the sewer line.
Flushing excessive toilet paper or not flushing often enough can cause the trap to become blocked.
Flushed Objects
Flushing non-biodegradable objects down your toilet is a surefire way to create a clog. Items such as diapers, hard paper, sanitary or hygiene items, and wet wipes will almost certainly clog your toilet at some point.
Avoid flushing these things to reduce the number of toilet clogs you experience.
Conclusion
So, there you have it, folks. The American Standard Champion 4 is our top pick for the best no-clog toilet overall. It has the largest flush valve, trapway diameter, and a 10 year warranty.
And remember, in your search to find the ideal clog-free toilet for your bathroom, be sure to pay attention to features such as flushing system times, flush valve, and trapway sizes.
The more powerful the flushing system on your toilet, the less likely it’ll be to clog. Hopefully, this list has given you some insight into a few of the best options out there when it comes to no clog toilets. And don’t forget to check out the reviews!
