7 Reasons Why Your Toilet Clogs So Easily

Woman cleaning toilet bowl in bathroom, closeup

While installing one of the best toilets for not clogging can undoubtedly give you freedom from clogging worries, it’s essential to learn why your toilet clogs so easily. Knowing these things can also help you avoid them and thus take good care of your toilets.

1. Too much toilet paper

A common reason that causes clogging is using the wrong type of toilet paper or simply the use of too much toilet paper. The toilet tissue should supposedly get dissolved when it touches water, but not all brands behave in that fashion. Sometimes you may find cheap toilet paper brands that refuse to fall apart.

If the toilet does not flush well even after repeatedly flushing water, this could be due to the accumulation of too much toilet paper or some form of organic matter. While the above toilet models can deal with such problems, we recommend that you avoid flushing too much toilet paper or the wrong brand of toilet paper to add more years to your investment.

2. Foreign objects

If you have a pet or kids in the house, then there can be many strange things that make their way into the toilet. These can be toys, bodily waste, food, paper, and so on. Unfortunately, kids like to experiment with a lot of things with household plumbing, causing nuisances.

We suggest that you keep the bathroom door closed at all times to deter curious toddlers and pets get into it. Sometimes guests may also throw objects such as sanitary pads into the toilet, causing clogging problems. So, make sure that you have a dustbin within easy reach.

For your new toilet’s long life and good health, ensure that the only things that go in there are toilet paper and bodily waste. So please avoid things like paper towels, so-called flushable wipes, and so on.

3. Poor Toilet Design

This can be a big problem, and many homes with old toilet designs often face this issue. When the toilet is not designed correctly or has a bad design, this may result in complaints such as low-flush toilets.

Some of the other aspects of the toilet that impact water flow are toilet drain throat, toilet shape, bowl angle, etc. To be on the safer side, we suggest that you check a new toilet with the MaP score, which should be 500 or more. MaP is an independent agency that gives ratings and scores based on various tests to toilets from different brands.

4. Lack of enough water in the tank

Is there not enough water with every flush? There could be a problem somewhere in the incoming water supply line, or it could be that the tank is not filling up enough. This results in not getting the right amount of water needed to clean the toilet bowl thoroughly.

First, check the knob on the water supply to ensure there is no problem with the water supply. If you cannot detect the problem, ask the plumber to come and check the tank.

5. A change of diet may be needed

If you frequently get into an embarrassing situation when the waste gets stuck on the bowl, this could be due to your heavily meat-based diet. We would suggest that you opt for a more fiber-rich diet to ease the bowel movements and get rid of this problem.

Try to include more servings of fresh fruits and green vegetables in your diet to prevent falling sick and keep hard stool problems at bay. In addition, you may consider discussing with your health expert to find out what can help in non-sticky and easy bowel movements.

6. Venting Issues

There could be a problem with your drainage system, and one of the most common problems is venting issues. The drainage system needs proper airflow to work and prevent vacuum forming. It is also necessary to hold the wastewater in place.

In case there is any problem with the ventilation pipe, then pressure may prevent a good flush. At times, the vent may have an awkward design or be installed incorrectly, leading to the problem. A mass of dried leaves may also cause the blockage.

7. Water may be too chlorinated

Check the quality of water you get in your locality because it could be a reason behind your toilet clogging frequently. If you get hard water, it contains minerals like calcium that get deposited inside the tank over time and inside the drain pipe.

This is a common issue if your toilet is old and consistently flushes poorly. To fix this problem, you may need to invest in a water softener or get the drain replaced. In addition, the water supply in cities often contains chlorine to kill the bacteria, which may have a damaging effect on the plastic or rubber parts of the toilet.

Related Questions

Can I use bleach to unclog a toilet?

Bleach is a substance high in chlorine, and thus it can break down and destroy organic materials such as hair, toilet paper, and other things containing fats. However, investing in one of the best toilets for not clogging can give you freedom from having to look for solutions to unclog the toilet now and then.

Why is my toilet flush weak?

If you get a hard water supply in your area, then it’s common to have mineral deposits such as calcium and lime, along with dust and debris, jam the holes of the toilet bowl. Over time, these accumulations of deposits grow larger, causing a weak flush.

How frequently should I clean my toilet?

Keeping your toilet clean can keep clogging issues at bay, and most experts agree that once a week is good enough if you don’t have any pets or kids in the house. However, if there are pets or kids, then daily cleaning is recommended. While the toilets mentioned above are designed to keep clogging at bay, they cannot deal with toys and other hard substances dropped into them.
