What is toilet unclogging and why is it important?
When the toilet no longer flushes properly or the water rises to the rim, you know it's time to unclog the toilet. Toilet drains often become blocked by a buildup of toilet paper, wet wipes, grease residue, and even limescale. Large objects, such as cleaning wipes or toys, can also cause blockages. Clogs aren't limited to the toilet itself but can spread further into the sewer system. This causes an unpleasant odor, increases the risk of flooding, and can damage pipes. Ontstoppen.nl We use advanced techniques and high-quality tools such as a spring machine or high-pressure sewer cleaning to efficiently and safely resolve any blockage.
How does unclogging a toilet work step by step?
Unblocking toilets is always done according to a clear and proven process where safety is paramount. Below, you'll see how we work when you contact us for toilet unblocking:
- Inspect and determine cause The first step is to analyze the blockage. We use camera inspection to map the problem so we know exactly where the blockage is located.
- Mechanical unblocking We often clear minor blockages immediately with a drain snake or hand tools. This prevents damage to the ceramic and pipes.
- High pressure flushing For stubborn blockages, we use a pressure washer. The water powerfully flushes away the blockage, dirt deposits, and caked-on residue.
- Check drain After unclogging, we test the toilet bowl and the entire drain. This ensures lasting results without any residual debris.
- Advice and prevention Finally, we provide maintenance advice, so you can prevent future toilet blockages with simple steps and smart tips.

Common causes of a clogged toilet
Unblocking a toilet always starts with identifying the cause. Each blockage requires a different solution. The most common causes we encounter are:
- Toilet paper buildup: Too much or thick toilet paper blocks the toilet's valve and slows down the flow.
- Insoluble materials: Wet wipes, tampons, sanitary napkins, or paper towels should never be flushed down the toilet. These products don't dissolve and quickly cause a persistent blockage.
- Grease, oil and soap residue: Especially in older houses, grease and soap residue clump together in the drain and increase the risk of blockages.
- Limescale: Hard water causes limescale deposits in the pipes, making the passage narrower and causing dirt to build up more quickly.
- Problems further down the sewer: Sometimes the problem lies deeper, for example, in the main sewer. We detect these blockages with camera inspections and resolve them using powerful professional equipment.
Professional techniques for unclogging a toilet
Don't be fooled: cheaply unclogging your toilet with household products can make the situation worse or damage your plumbing. We always tackle toilet blockages thoroughly using certified methods, based on knowledge of NEN-EN 12056 (the standard for drainage systems in buildings) and guidelines from the Dutch Association of Sewerage Contractors. Years of experience in Amsterdam, Rotterdam, Utrecht, and other major cities have taught us exactly which technique works best at which time.
- Feather machine: This flexible tool penetrates deep into the pipe and breaks the blockage without damaging the pipe.
- High pressure sewer cleaning: With a powerful jet of water we remove grease, limescale, hair and other stubborn dirt from every pipe.
- Camera inspection: By pushing a small camera through the pipe, we can capture even the most difficult-to-reach blockage in crystal clear detail.
- Locating with smoke detection: Sometimes the blockage isn't visible, for example, with a leak under the floor. We use smoke to detect where the drain is blocked, without any demolition work.
Unclogging a toilet: types of blockages and unique solutions
The type of blockage determines the best approach. We distinguish between different types of blockages, each with its own characteristics and methods.
- The local blockage: This is a blockage near the toilet, often caused by too much paper or a foreign object. The solution is a spring or a manual pump.
- The main sewer blockage: This problem occurs deeper in the sewer system. Think of an ingrown tree root or a stubborn blockage, which can be remedied with high-pressure cleaning.
- Recurrent blockage: When a toilet repeatedly clogs, there's often a structural problem, such as an incorrectly installed pipe or drainpipe. We schedule specialized investigations and a lasting solution for this.
- Blockages due to limescale: A common problem in regions with hard water, such as Utrecht and Rotterdam. We have certified products to effectively remove this deposit without damaging the pipework.
Preventing toilet blockages and smart prevention tips
Prevention is always better than cure. With simple adjustments to your daily routine, your toilet will continue to flush smoothly for years to come.
- Only flush toilet paper: So no wet wipes or hygiene products.
- Limit the use of cleaning tablets: Some cleaning products cause build-up in the pipes and promote blockages.
- Prevent grease in the drain: Never pour grease or oil down the toilet.
- Minor maintenance: Clean the pot occasionally with soda and hot water to prevent dirt build-up.
- Check in time: If you are bothered by bubbling sounds or bad smells, have it inspected promptly to prevent bigger problems.

Frequently asked questions
What are the most common causes of a clogged toilet?
A toilet usually clogs due to an excess of toilet paper, wet wipes, or other objects accidentally flushed down the drain. A buildup of grease, limescale, or hair in the drain pipes can also cause a blockage over time. This is especially common in older homes where pipes are narrower or not properly drained.
We often see household products like paper towels or hygiene wipes being used instead of regular toilet paper. These dissolve much less quickly and accumulate in the drain. Want to know how to have your blockage professionally cleared? Then read on to learn more about our professional toilet blockage removal service.
What can you do yourself if your toilet is clogged before calling a professional?
You can first try using a traditional toilet plunger. Make sure you use a good suction cup and move the plunger firmly up and down to create a vacuum. Sometimes pouring hot water into the toilet (never boiling hot, to prevent damage to the porcelain) and waiting twenty minutes to allow any soft blockages to dissolve.
