What is toilet clogging & how to know your toilet Clogged?

When your toilet begins to drain slowly. It means that after flushing the toilet, the toilet bowl began to fill with water, and the waste remained in the toilet after draining.

However, if you do not flush your toilet, you will not know if it is clogged or not.

So the question is, how do you know? right

1.After flushing the water stayed in the bowl for a long time.
2.Water starts to gurgle up in either shower or bath drain after you flush the toilet.
3.After flushing overflowing from the bowl may happen.

It’s not a big deal to unclog a toilet, but it takes time and can result in toilet rings, which is why a non-clogging toilet is a great option for your home.

How to protect toilet from clogging

There is more than one cause of toilet clogging. We’ve listed a few of them.

  • Avoid extra use of toilet paper
  • Don’t use a toilet like a dustbin
  • Manual cleaning need occasionally
  • Close the lid after use.

If you are puzzled about a wide range of features, we have compiled a list of essential factors to examine before purchasing a no-clog toilet.

Factors must be considered before purchasing a no-clog toilet

Toilet played a vital role in our house. When you searched for no-clog toilets, you must be looking for the best performing toilet.

Check the lists-

Mapping Score

The mapping score represents the gram of waste removed by a single flush. The highest mapping score indicates that the toilet has a more powerful flush that prevents clogging.

Like Woodbridge, T-0019 has eliminated 1000 grams of waste per flush.

Trapway

Trapway height is also important because a taller trapway provides a more powerful flush than a standard trapway. Toilets with a 3″ trapway provide a more powerful flush.

Flushing systems

Two primary flushing technology are present in the market. The first one is gravity flush, and the second one is pressure assist flush.

If you want a powerful flush while also saving water, dual flush toilets are the way to go. In this scenario, these are the best options.

Large flush valves are also crucial for a forceful flush that also minimize jamming.

One or two-piece toilet:

Both toilets have a strong flush system, but you have to decide according to your comfort.

In comparison to two-piece toilets, one-piece toilets are best for any bathroom because of their sleek design, ease of cleaning, and leak-proofing features.

Two-piece toilets are cheaper compare to the one-piece toilet.

Round or elongated:

An elongated bowl is more comfortable than a round one and has a minimum corner; that’s why it’s easy to clean.

Round toilets are perfect for a small bathroom because of the space.

Warranty:

I love the warranty section because it eliminates lots of headaches. Always go with at least one year warranty. Some high-profile brands also provide a five-year warranty.

Before ordering any item, reconfirm the warranty section because it may change according to the model.

There are some other factors also presents that are not major things for a nonclogging toilet. 

But you have to check it and confirm it according to your need such as design, ease of installation or not, toilet seat and other components are included or not, verify the height is comfortable or not, and so on.

Okay, let’s jump to the exciting parts that are our products.
