Clogged toilet: Causes and how to flush quickly
Everyone has experienced it at some point: the toilet suddenly won't flush anymore and stress immediately arises. Ontstoppen.nl We're ready to provide expert assistance if your toilet is clogged. We provide solution-oriented service thanks to years of experience with toilet blockages, sewer problems, and plumbing systems that comply with the latest NEN standards and the Dutch Building Decree.
A clogged toilet at home or in a business can have several causes, such as backed-up toilet paper, wet wipes that don't dissolve, or limescale buildup. Sometimes the problem is more serious: a blockage further down the sewer system, tree roots in the main sewer, or a faulty drainage system installation. As specialists in sanitary cleaning, we immediately identify the root of the problem and resolve toilet blockages quickly and professionally.
Reasons Why Your Toilet Gets Clogged
The causes of a clogged toilet vary enormously. Based on our knowledge of plumbing and experience in thousands of homes and businesses, we know exactly what to look for. Key causes include:
- Using too much toilet paperExcessive paper causes a blockage just past the toilet bowl, especially if you choose extra thick or moist toilet paper.
- Flushing insoluble materialsCotton swabs, tampons, sanitary towels, diapers and hygiene wipes absolutely do not belong in the toilet and often remain there.
- Blockages further down the sewer: Grease, food residues and limescale can build up to a stubborn blockage deep in the drain pipes.
- Tree roots in the pipeIn older city districts such as Rotterdam and Amsterdam, tree roots sometimes grow straight through stoneware pipes into the main sewer.
- Incorrect installation or sagging pipesIf pipes do not have sufficient slope, wastewater can easily accumulate and waste can quickly build up.
Toilets also clog more quickly in buildings where many people use the restrooms in a short period of time, such as restaurants, educational institutions, or businesses.

Different types of toilet blockages
Not every blockage is the same. The location and severity of the blockage require different unblocking techniques. We distinguish:
- Local toilet blockage: Paper, tissues or playing pieces immediately block the bottom of the pot.
- Drain pipe blockage: The blockage is between the toilet and the standpipe/collection sewer, which is recognizable by slow emptying and a gurgling sound.
- Main sewer blockage: Water is rising in multiple drains in the house, such as the toilet and sink. This is often a blockage at a greater depth.
- Limescale and urinary stones: Long-term use or hard water causes a narrowed pipe.
We work exclusively with professional drain cleaning equipment such as spring machines, camera inspections, and pressure washers, enabling us to tackle any type of blockage. Our approach is safe for pipes and prevents damage to ceramic and PVC pipes.
How does the process of unclogging a toilet work?
If your toilet is clogged, we always handle it in a structured manner, following the protocols that apply within the Dutch professional sector:
- Problem detection: Determine the nature and location of the blockage using a mechanical method or camera inspection.
- Choosing a drain cleaning strategy: Depending on the type of blockage, we opt for springs, pumps, or high-pressure cleaning. In critical cases, a chemical cleaning agent can be used temporarily, always within the legal framework for environmentally friendly applications.
- Resolving the blockage: We resolve the blockage on-site. This may involve removing paper wads, milling out stubborn limescale, or flushing out grease deposits.
- Functional test: After unblocking, we immediately test whether the toilet is flowing properly again.
- Advice and reporting: You'll receive preventative advice to prevent future problems. If necessary, we'll provide a quote for structural repairs to old or damaged sewers.

Frequently asked questions
How do you know if your toilet is clogged and what usually causes it?
You can recognize a clogged toilet by water that doesn't drain properly, gurgling sounds, or even flooding after flushing. The problem is often caused by too much toilet paper, wet wipes, sanitary towels, grease residue, or even toys. Inadequate drainage or limescale in the sewer can also be the cause.
Frequent blockages sometimes indicate a deeper problem, such as tree roots in the main sewer or a subsidence of the drainpipe. If the problem persists, it's wise to have your toilet professionally inspected and unclogged by experienced plumbers to prevent major damage. See our tips on unclog toilet without chemicals for more information about tackling the problem safely yourself.
What can you try yourself if your toilet is clogged?
If you notice the water level rising in the bowl or it's not draining, you can first use an old-fashioned toilet plunger. Make sure there's enough water in the bowl, place the plunger firmly over the drain hole, and pull firmly. If the blockage is more serious, a special flexible spring or tension spring can help you manually pry it loose.
Never try harsh drain cleaners; they can damage pipes and are often counterproductive. Sometimes, hot water with a little dish soap helps with a minor blockage caused by grease or paper. Don't succeed with these tricks? Our professionals can safely and quickly clear the entire drain using specialized equipment, without damaging your toilet.

What risks do you run if you ignore a toilet blockage or don't resolve it (properly) yourself?
Allowing a clogged toilet to persist can lead to flooding and significant water damage in your bathroom or home. Sewage can back up, causing unpleasant odors, mold growth, and even health problems due to the presence of bacteria from the sewer system. Besides the immediate inconvenience, ignoring the problem can also cause structural problems such as leaks, pipe subsidence, or even ruptures in the sewer system.
If you handle the drain yourself unprofessionally with sharp objects or aggressive agents, you could damage the bowl, drain pipe, or trap. Such damage will lead to even higher repair and unblocking costs later. If in doubt, prevent this by consulting a qualified specialist.
