What To Consider When Buying A Toilet That Doesn't Clog

When shopping for no clog toilets,  you need something to give you a powerful flush to clear any waste in the toilet bowl without leaving any remains. When searching for one, there are a few quick guidelines and things to consider before you buy it. 

no clog toilets

Flushing System Type

Flushing toilets can either have a siphonic (gravity) or a pressure-assisted flushing system. The siphonic flushing system utilizes the weight and the pressure of water to channel the waste to the sewer line.

On the other hand,  the pressure-assisted flushing mechanism uses compressed air to push water out of the tank through the bowl to the sewer line. Toilets with a pressure-assisted flushing mechanism are much more potent than siphonic toilets. 

Since they’re stronger, they’re often a much better option for reducing the chance of clogs at any point in your plumbing system. You also don't run into issues with weak flushes as often either.

Flush Valve Size

The size of your toilet flush valve dictates how fast the water can leave the toilet tank into the toilet bowl. Typically, most flush valve sizes range between two and four inches. The larger the valve, the faster the water can clean the bowl. It’s worth purchasing a no clog toilet with a large flush valve if you’re worried about obstructions. 

It’s important to note that each toilet already has a specified size flush valve it works with. So you can’t simply purchase a larger four-inch valve for a toilet that uses a two-inch flush valve. 

Trapway Size

Trap way refers to the S-Shaped pipe that channels the waste and flushes water to the sewer line. Aim for toilets with a larger trapway as they allow for efficient passage of waste, reducing the possibility of clogs and obstructions. Don't forget to clean your pipes every now and then either.

Construction Design

Flush toilets come in one-piece and two-piece toilet designs. The one-piece toilet designs are sleeker and easier to clean than their two-piece counterparts. On the other hand, the two-piece toilets are more straightforward to repair than the other variants making them cheaper to maintain. The initial purchase cost for two piece toilets is relatively lower than the one for their one-piece counterparts. Knowing the differences between the two, it comes down to choosing between a more aesthetic style or budget.

Toilet Bowl Type

Typically, toilet bowls come in elongated, rounded, and square designs, with the square design being the least popular. Toilets with elongated bowls offer the most pleasant seating area. However, they feature large sizes and are thus ideal for large bathrooms.

The rounded toilets are smaller than their elongated variants. While they’re less comfy than their elongated counterparts, they fit pretty well in small bathrooms. The choice between the three toilet designs remains a matter of your taste and preferences.

Installation Needs

Flush toilets come in various designs, so they also have different installation requirements. Compare different options to pick the one you can install flawlessly without the help of a professional. But if you’re older and want a professional contractor to do it for you, it might not matter too much.

Toilet Height

When shopping around, choose a toilet with a comfortable height depending on your physical size and abilities. The average toilet height to the rim is approximately 16 inches. People who are taller, elderly, or those with physical disabilities, will find those with a toilet heigh that’s at least 18 or 19 inches a preferable option. 


Having learned about different toilets that don’t clog up and considerations to keep in mind, it's your turn to pick your most preferred option. Our overall best pick is the White Champion 4 one-piece toilet by American Standard

It offers a four-inch large flush valve that allows for a fast and powerful flush without wasting any water. Remember that your ideal choice might differ from others since it depends on several variables like how big your bathroom is, how often it’s used, preferred toilet height, and more. 

As a rule of thumb, the stronger the toilet flush, the less likely you are to run into any issues with clogs.
