The piping system of your home allows for the drainage of wastewater. However, to ensure this function, it must be well maintained. A clog or blockage in your pipes can be caused by significant limescale buildup, the accumulation of organic waste in the pipes, or the deposit of inappropriate objects in the toilets. As soon as such a problem appears, it is essential to act as quickly as possible. But how to get rid of a clogged pipe? What are the signs of a clogged system? Here are some answers.
📋 What to remember: Personally, I consider that 80% of domestic clogs can be resolved without harsh chemical products thanks to the mechanical action of a plunger or a drain snake. The preventive use of a mixture of baking soda and vinegar once a month drastically reduces the risk of total blockage. I recommend intervening at the first gurgling sounds, as a backing-up pipe can cause water damage costing more than 500 euros in repairs.
How to proceed to unclog a pipe?
Several methods can be used to unclog a pipe. However, their effectiveness will depend on the severity of the clog and its location in your pipe system. From making a natural product to calling a professional, and using the right tools, there are multiple solutions to remove the foreign object responsible for the blockage of your pipes.
🗣️ My experience: In 2024, I was called by a friend whose sink was completely blocked. He had poured three bottles of acidic drain cleaner without success, which ended up softening his PVC pipes. We had to dismantle the entire siphon to extract a solidified grease clog that only manual action could dislodge. The lesson learned is clear: never force with chemicals; a simple 15-euro drain snake would have solved the problem in two minutes without damaging the installation.
Using a natural product
| Method | Effectiveness | Difficulty | Material risk |
|---|---|---|---|
| Boiling water | Low (Grease) | None | None |
| Plunger | Medium (Clog nearby) | Easy | None |
| Manual drain snake | High (All types) | Medium | Low |
| Chemical drain cleaner | Variable | Very easy | High (Corrosion) |
Many chemical products are sold commercially to unclog pipes. However, you can also make your own product, which is more economical and more environmentally friendly. To do this, you need to have baking soda and white vinegar. To eliminate the clog, pour a few tablespoons of baking soda into the affected drain, then add a glass of white vinegar. Cover everything with boiling water. The chemical reaction will dissolve the clog. Note that this solution is only effective if the clog is small.
💡 Practical tip: Place a basin under the siphon before unscrewing it. A siphon always contains about 50cl of stagnant water and foul debris. Take the opportunity to clean the threads and check the condition of the gasket before reassembling.
Using the right tool
If using a product does not clear the clog in your pipe, do not hesitate to use some tools. A plunger, thanks to the creation of a vacuum, can help you bring up the clog and remove it quickly. You can also use a manual or electric drain snake. To do this, simply insert the head of the device into the pipe and gently turn it until you reach the clog. Then, make several back-and-forth movements to eliminate all impurities.

What are the signs of a clogged pipe?
Several signs can alert you to the condition of your pipes and warn you of the presence of a clog inside them. Here are what they are.
Difficult water drainage
After using your shower, sink, or washbasin, is the water slow to drain? Does a certain volume of water remain stagnant at the bottom of your fixtures? This is undoubtedly a sign that debris or impurities are blocking your pipes and preventing water from draining properly.
A foul odor
Strong foul odors are coming back into your apartment or house? This is a sign that your wastewater is stagnating in the pipes and cannot be properly evacuated. Besides being very unpleasant for the occupants, it also promotes the proliferation of bacteria and increases the risk of disease development within the home.
Noises in the Pipes
The presence of a clog in the pipes can also cause plumbing noises. If you frequently hear gurgling inside your pipes, you need to act quickly before the blockage becomes too severe.
