We found out that the best no-clog toilets for home come in different designs and price points, making it easy to pick a toilet you can use for years without having to break the bank.

Our decision to switch to no-clog toilets came after a nasty incident a few years back.

It was a typical day at home: I was working in my home office when we heard a piercing scream from our downstairs bathroom. My wife and I ran down only to find own our eldest standing in the doorway with one hand over their mouth and the other pointing at the toilet, which was overflowing.

Upon calling the plumber we discovered the clog was caused by paper towels. The plumber advised us to replace that toilet with a no-clog one to avoid regular call-backs.

We ended up replacing all our toilets once we discovered how seamlessly the no-clog toilet worked. As I was researching options for no-clog loos, I found that so many Americans go through the hassle of clogged toilets every day.

Ultimately, we discovered that while no-clog toilets were relatively more expensive than the standard ones, they are ultimately worth the investment

In this article, I’ll cover the findings of my research and give you valuable tips I learned along the way on how to avoid clogs altogether.

How No-Clog Toilets Work

A clog-free toilet is one that doesn’t get clogged by design. This is achieved through a combination of high flow flushing and a powerful siphoning mechanism that uses enough pressure to clear all the waste from the bowl while still using significantly less water than other models.

High-Flow Flush Design

Many toilets manufactured before the 1990s used low-flush mechanisms. The poor design of low-flush toilets meant reduced sewer flow, which resulted in clogging. In addition, these toilets sometimes required two or more flushes to properly eliminate waste from the bowl.

Today’s no-clog toilets use a high-flow mechanism while still retaining water savings. These high-efficiency models use the following high-flush mechanisms:

  1. Pressure. Pressure-assisted toilets use a clever way to store and release air pressure. A plastic tank inside the toilet tank gets pressurized gas as water flows into the main tank.



    Once the pressure reaches an optimum level, it shuts off the flow of incoming water that fills up your commode. The mechanism also keeps both gases sealed away until you push down on a flush button or lever at which point everything releases so fast and forcefully that everything inside the bowl is flushed.

  2. Flushometer. The flushometer mechanism uses a valve that automatically closes once the toilet is flushed, stopping water flow. This mechanism eliminates the need for storage tanks while still producing high-pressure flushes.



    In addition to reducing clogging, another notable result of high-pressure flushing is a more efficient cleansing than gravity alone can provide. The flushometer system achieves this while still using the same quantity of water as the standard toilet (1.6 gpf or less).

  3. Double cyclone. Models using this flushing mechanism have both gravity and high-pressure systems that produce a powerful flush.

  4. Larger trapway. The trapway is the “S” shaped waterway in your toilet that drains water and waste from the hole in your toilet bowl to the waste disposal system such as sewer or septic tank.

    The “S” curve serves two main purposes: it creates a barrier that stops sewer gas from traveling up your drains and collects waste in the standing water that collects inside the bowl before flushing occurs.

    Clogging can happen when non-flushable items such as paper towels, female sanitary products, or non-flushable wet wipes get trapped in the trapway.

    No-clog toilets have larger trapways that make it easier for waste to flow from the bowl to the sewer line or septic tank, thereby preventing clogs.

    Many no-clog toilets have larger than the standard 2-inch wide trapways. For instance, the TOTO Eco Drake features a large 2 1/8-inch trapway that makes flushing a breeze!

Why You Need a No-Clog Toilet for Your Home

If you’re sick of your water bill, listen up. Older toilets use 5-7 gallons per flush but no-clog models only need 1.6 or less! This can save hundreds to thousands of dollars a year and keep sewers from getting clogged with toilet paper too often (which is disgusting).

Today, there are toilets dual-flush systems that use different amounts of water to flush liquid and solid waste. These toilets have two buttons: one for liquid and the other for solid waste flushing.

They use less water for flushing liquid while the system releases just enough water quantity and pressure to flush solid waste.

Toilets with the double flush feature are more eco-friendly because they can use half as much water for a quick flush but just as clean.

Many people don’t realize just how much they waste on average by flushing their toilets five times every day which is why it pays off, in the long run, to invest in a $200-700 no-clog fixture.

This toilet will pay for itself after 1-2 years – particularly in terms of all the money saved over time preventing sewage backups caused by old conventional style fixtures.

Based on the average person flushing five times a day, about 300 gallons of water per year is wasted in just that one aspect. So, get yourself and your home as low-water-use as possible by installing an eco-toilet!

In 1992 President George H. W. Bush signed the Energy Policy Act requiring all toilets installed in homes after January 1, 1994 to use a maximum of 1.6 gallons per flush (gpf).

Since the enactment of this federal statute, toilet manufacturers have been working to come up with high-efficient flush mechanisms that use the least amount of water.

Most no-clog models use a low-flush mechanism, which uses less than the standard 1.6 gpf. Low-flush toilets are designed so the water flows with enough force and in the right direction, leaving no waste sitting in the bowl.

I was excited to learn that the TOTO Eco Drake that we installed in our downstairs bathroom uses only 1.28 gpf! This toilet is built to save water!

No-clog toilets are a perfect solution to toilet clog problems. They are easy to clean, but more importantly, they do not require regular maintenance. Basically, toilets that do not clog can last for decades without requiring replacement.

These toilets ensure your bathroom is always clean and presentable, which makes them an excellent investment in the long term.

Frequently Asked Questions (FAQs) about No-Clog Toilets

Q. How Can I Tell if My Toilet is Low-Flush?

A. The date of manufacture can be a good indicator. Check for the date of manufacture on your toilet. While different models will have the date in different places, most manufacturers inscribe the date on the underside of the toilet tank lid, or inside the tank (typically above the waterline). Many newer models will also have marking indicating the unit’s gallon per flush.


Here’s how to use the date of manufacture to check if your toilet is low-flush:


A toilet manufactured before 1990 will have a full flush mechanism, meaning it uses 5-6 gpf. One manufactured between 1990 and 1992 will generally use between 3.5 gpf. A toilet manufactured between 1992 and 1994 could use between 1.6 to 3.5 gpf. However, any toilet manufactured after 1994 will use 1.6 gpf, or less.

You can also check for the below WaterSense Label that certifies that a toilet meets high efficiency and performance standards.




Q. Can a Toilets Unclog Itself

A. No-clog toilets do! These models are designed to never get clogged up with debris or waste like other models might. Toilets that don’t clog will always offer consistent and powerful flushes which will keep your bathroom clean and sanitized.

Toilet clogs can be such a hassle to deal with, if you don’t have time or the patience for that kind of task then investing in a no-clog model is worth it!

Q. Can a Toilets Unclog Itself

A. Before we changed all our toilets to no-clog ones, we found that having a plunger and auger handy is critical for when toilet emergencies happened. Check out this video on fixing overflow issues:

Q. Does Toilet Drain Matter When Installing a No-Clog Toilet

A. Toilet drain is an important consideration when installing a no-clog toilet. No-clog models come in two different styles: the traditional siphon jet system and a gravity-fed draining system. Toilets with this latter type are more durable and don’t clog as easily because they have an extended drain pipe that can be sealed with an airtight stopper.

Q. How Do High-Flush Toilets Help the Environment

A. A single flush of a toilet has little impact on the environment in comparison to flushing it several times. Toilets with high-flush capabilities have this additional feature that significantly reduces water use by up to two gallons and can save up to 18,000 gallons of water per year.

Toilet models with this mechanism deliver a powerful wash while using less water through jets that push off liquids directly from the bowl and trap solids in an enclosed area before releasing them into wastewater systems.

These no-clog toilets are among the most cost-effective considerations for green living or remodeling throughout any home today.

Final Thoughts

Toilet clogs happen for many reasons, but thankfully there are ways to prevent them from happening at all! Toilet manufacturers have come up with a variety of clog-free toilets that can handle all sorts of bathroom needs.
