When the pipes are working normally, water drainage occurs without odor, noise, or difficulty.
However, at some point, water rises when you flush the toilet. It must be admitted that this phenomenon causes inconvenience with each use.
Faced with this situation, one sometimes wonders can plumbing be done oneself. This article provides you with various solutions to fix this problem. To begin, it is appropriate to mention the possible causes.
📋 Key points: Personally, I consider that the accumulation of grease and hair is responsible for 60% of domestic clogs. I believe that monthly preventive maintenance helps avoid costly emergency interventions. In 2026, adopting simple actions such as using a strainer remains the most concrete solution to preserve the health of your plumbing.
Why does water rise in my shower?
🌍 Did you know? A single tablespoon of frying oil poured into the sink can pollute up to 1000 liters of water and create a clog several centimeters thick as it cools in your pipes.
Generally, this unexpected water movement is due to a clog. It is made up of a pile of waste such as soap or paper debris, hair, limescale deposits, and much more.

📍 My experience: Last January, I had to spend 180 euros for an emergency unclogging because I was systematically throwing my coffee grounds into the sink. Contrary to popular belief, grounds do not clean; they clump with grease to form a solid clog. The lesson I learned is that a trash bin is always cheaper than a plumber.
When water cannot flow downward, it rises accordingly in the shower. To prevent the problem from worsening, it must be resolved as soon as possible.
For further insight, I advise you to read how to unclog a dishwasher drain, which is often the first victim of grease. Knowing how to unclog a clogged pipe will also give you useful tips. And to go even further, learning how to remove an object from a pipe provides interesting insight into everyday incidents.
Why does water rise in the pipes?
When you call a plumber, they often find a stuck object in the pipes. Often, children accidentally throw certain things that clog the network and hinder the flow of water. As a result, the water ends up rising in an inappropriate place.
It may also be that the pipe is not clogged, but the rise of water is explained by the reduction of water flow. Consequently, the water finds another path in the opposite direction.
Whatever the reason, it is urgent to find solutions. Otherwise, the condition of the pipe worsens, which can lead to a possible flood in the house.
⚠️ Common mistake: Using caustic soda repeatedly to unclog. If the blockage does not clear, the product stagnates, heats up, and can deform your PVC pipes or worse, crystallize and turn a simple clog into a block of chemical concrete.
How to unclog a shower drain?
If you are used to natural products, opt for the mixture of white vinegar and baking soda. Just pour the solution into the affected drain and that’s it. After 30 minutes, rinse with clear water.
Alternatively, boiling water is effective for cleaning. You just have to pour it directly into the drain pipe. Also, it is possible to add coarse salt.
🌟 Advantages
- Natural methods that respect the pipes.
- Significant savings in the long term.
- Elimination of bad odors.
🔍 Drawbacks
- Ineffective on already solid clogs.
- Requires some regularity.
For chemical methods, unclogging products are found everywhere in supermarkets or specialized stores. Since they are quite aggressive, waterproof gloves must be used when handling them.
| Type of waste | Clog risk | Frequency | Effect on pipes |
|---|---|---|---|
| Food fats | Very high | Daily | Progressive clogging |
| Hair and fur | High | Weekly | Formation of fibrous clogs |
| Soap residues | Medium | Daily | Reduction of diameter |
| Unusual objects | Immediate | Rare | Complete blockage |
💡 Tip: Pour 1/2 cup of baking soda followed by a cup of white vinegar once a month. Let it act for 30 minutes before rinsing with hot water. It’s the winning duo for healthy maintenance.
How to unblock a completely clogged pipe?
If you want quick results, nothing beats using a plumbing snake. This tool is designed to remove the blockage inside the pipes.
It is equipped at both ends, one of which has a hook used to retrieve the blockage and the other with a handle for the rotating movement.
A plunger also allows you to clear a completely clogged pipe. It creates an air suction inside the plumbing.
To use it, place it over the drain hole and make pumping or back-and-forth movements to suction the blockage. Repeat the operation until the pipe is completely unclogged.
If these methods do not work, consider calling in an sanitation expert.
As a professional, they are equipped with the appropriate tools to solve the problem as quickly as possible. The technician suggests a high-pressure unclogging solution for optimal efficiency.
Clogged upstairs toilet, water backs up into shower and bathtub
When the toilet is clogged, water sometimes backs up into the bathtub or shower. To fix this issue, you can use dishwashing liquid.
This is not only used to clean your utensils or remove a stuck ring. Thanks to its lubricating action, it is also effective for treating clogged toilets.
To do this, mix it with hot water and then pour the mixture into the toilet bowl. After 15 minutes, flush.
If home remedies do not work, do not hesitate to use stronger methods with a high-pressure cleaner. Since it propels water at high pressure, it cleans impurities and dislodges the blockage, no matter its size.
