A high water level in the bowl, unpleasant odors, or unusual noises are all signs of a clogged toilet. If a clog is left unresolved, it can lead to water leaks or even liability for damages. In this article, we explain what causes toilet clogs, how to clear them yourself, and how to choose the right service provider.
What causes a toilet to clog?
Toilet clogs usually happen for a few common reasons. Understanding the cause helps you choose the right solution.
Flushing too much at once
Toilet paper and waste dissolve in water, but if too much is flushed at one time, it may not break down fully and can cause a blockage. The risk is especially higher when the toilet is set to eco mode with reduced water volume.
Flushing absorbent foreign objects
Items such as diapers, pet litter, and sanitary products absorb water and expand. As a result, they can block the drainpipe. This type of clog is often difficult to clear on your own and frequently requires professional service.
Flushing insoluble objects
Accessories, toys, glasses, and other insoluble items can block the drainpipe. If this goes unnoticed for some time, identifying the cause can become more difficult.
Buildup of urine scale and dirt
With years of use, urine scale can harden inside the drainpipe and reduce water flow. Regular cleaning is an effective preventive measure.
How can you clear a toilet clog yourself?
Unless a foreign object was accidentally flushed, many clogs can be cleared without professional help.
Use a plunger
This is the most standard approach. Press the plunger firmly over the toilet drain opening, then repeat pushing and pulling motions to loosen the clog. To prevent water from splashing, protect the surrounding area with towels or a protective sheet first.
Use baking soda and vinegar (or citric acid)
Pour 200 g of baking soda and 100 ml of vinegar (or citric acid) into the drain opening, then add hot water at around 60 degrees Celsius and let it sit for about 30 minutes. This method is effective for clogs caused by organic matter and for light urine scale buildup.
Use hot water
This method involves pouring water at 60 to 70 degrees Celsius into the toilet. Boiling water should be avoided because it may damage the ceramic. It is effective for light clogs and greasy residue.
Use a plastic bottle to apply pressure
This is an alternative option if you do not have a plunger. Place the mouth of the bottle against the drain opening and squeeze to create pressure. It is not as effective as a plunger, but it can still be useful as a temporary measure.
When should you call a professional, and how do you choose one?
If the clog is difficult to clear on your own, you should contact a professional service provider.
Situations where you should call a professional
- You flushed a foreign object such as a diaper or toy
- The problem does not improve even after trying to clear it yourself
- Water continues to overflow or sewage is backing up
What to look for when choosing a provider
- The estimate should be clear and the cost should be explained before any work begins
- Choose a company that holds the Ministry of Land, Infrastructure, Transport and Tourism's "Drainpipe Cleaning Contractor" certification
- Confirm whether emergency service and 24-hour support are available
- Compare reviews and track records across multiple companies
Who pays in a rental property?
In a rental property, who bears the cost depends on the cause of the clog. If the issue was caused by improper use by the tenant, the tenant is generally responsible for the cost. If it was caused by aging equipment or plumbing issues, the landlord or property management company is usually responsible. Contact the management company first and confirm whether they require a designated contractor.
Frequently Asked Questions (FAQ)
Q. What should I do first when my toilet is clogged?
First, stop flushing to prevent the toilet from overflowing. Next, check the likely cause, such as a foreign object or too much paper, and then try using a plunger or baking soda with hot water.
Q. I flushed a diaper. Can I fix it myself?
A swollen diaper can easily become lodged in the drainpipe, making self-repair extremely difficult. Contact a professional service provider as soon as possible.
Q. Can I use baking soda and vinegar together with toilet cleaner?
Mixing chlorine-based cleaners with vinegar, which is acidic, can produce toxic gas. If you have used a commercial cleaner, rinse thoroughly with water before using baking soda and vinegar.
Q. If my toilet is clogged in a rental property, can I call a contractor without contacting the management company?
As a general rule, you should contact the management company first. If you arrange a contractor on your own, you may end up paying the full cost yourself. Even in an emergency, try to reach the management company first.
Q. How much does it usually cost to call a professional?
For a minor clog, the typical cost is around 10,000 to 30,000 yen. If foreign object removal or high-pressure cleaning is required, the cost can rise to 30,000 to 100,000 yen or more. It is advisable to compare estimates from multiple companies.
