How to Unclog a Toto Toilet

Toto toilets have become increasingly popular through the years, thanks to their innovative bathroom designs, high quality, and luxurious features. 

However, despite this toilet brand’s top performance, Toto toilets will clog up from time to time, just like any other toilet. When this happens, you have to use special tools to unclog it because of how the brand builds its toilets.

A lot of things can cause a Toto toilet to clog up. For instance, you may have flushed something down the toilet that shouldn’t have been, and it’s now obstructing the drain line. It may also have a faulty toilet trap or react poorly to hard water.

Why Is My Toto Toilet Clogged Up?

Most people do not stop to think about how vital their toilet is until something goes wrong with it. Of the various problems that can arise with a Toto toilet, clogging is the most common one but also the easiest to deal with. So why is your Toto toilet clogged up?

Clogged Drain Line

People will often throw things into the toilet without thinking twice about it: Q-tips, baby wipes, sanitary items, and even toilet paper rolls. These items get into the toilet drain line and block it. Children will often flush even worse things down the toilet, such as plastic toys.

A clogged drain line is a common issue with a lot of regular toilets, though less so with Toto toilet models, thanks to their unparalleled flushing capacity. Still, it can happen.


Even high-end toilets such as Toto toilets will wear down as time goes by, resulting in problems such as leaks and clogs.

If your Toto toilet is relatively new, it should work flawlessly for years to come. However, older residential toilets tend to have technical issues more often and require more upkeep.

Faulty Toilet Trap

Toto toilets such as the Drake models are designed with a flush system that uses a 3-inch wide flush valve and a 2-1/8 inch trapway. This results in more flushing power than standard toilets. 

Water is pumped into the bowl so fast that the siphoning effect in the toilet trap normally prevents clogging. A faulty toilet trap can slow down the water and reduce the flushing water, increasing the chance of clogs.

Hard Water 

Not all water provided by local governments is the same. Hard water has minerals in it such as calcium that slowly build up inside the toilet and eventually clog it up. This is referred to as calcification.

Do Toto Toilets Clog Up More than Other Toilets?

A clogged-up toilet can be a pain to deal with, especially if you are in a hurry and cannot deal with it right away. If your Toto toilet has clogged up more than once now, you might start to wonder whether this brand of toilet clogs up more often than others.

Most plumbing experts would agree that Toto toilets clog up a lot less often than other toilets because they use high-powered water jets and other features to prevent materials from clumping together and blocking the pipes.

But if your Toto toilet has gotten clogged despite these features, consider the advice below:
