What does a clogged drain mean and why does it happen?
A clogged drain immediately causes problems in your home or business. You quickly notice it: water no longer drains, unpleasant odors spread, and plumbing fixtures are barely usable. The drain, along with the sewer system, forms the main infrastructure for removing wastewater from toilets, kitchens, bathrooms, and laundry rooms, according to the specifications of NEN-EN 12056 (drainage systems for the built environment). In the Netherlands, daily drainage problems are common, partly due to overused pipes, dirt accumulation, and improper use.
Drains can become clogged for a variety of reasons. These include grease and food residue in the sink, hair and soap scum in the shower, limescale buildup, and even small objects that disappear into the pipes. Roots from trees around the house also cause damaging blockages in the external sewer system. Water boards like Waternet and Vitens advise against flushing grease and solid debris down the drain to prevent blockages permanently.
- Grease and food residues: Residue in the kitchen drain will build up against the pipe wall and eventually cause a complete blockage. Always use a strainer in the sink.
- Hair and soap residue: Especially in the shower and sink, hair and soap form a solid clump that prevents water from passing through. Regular cleaning is essential.
- Limescale deposits: In areas with hard water, limescale builds up in pipes. A descaler or regular rinsing can help prevent this.
- Foreign objects: Many blockages are caused by flushed wipes, sanitary waste, or children's items. These can only be removed mechanically.
How do we professionally solve a clogged drain?
The unblocking process of Ontstoppen.nl starts with diagnosis. Our experts use techniques like camera inspection, developed according to the latest technology standards, such as the RIDGID SeeSnake camera and Bosch Moisture Meter. This way, we pinpoint the exact location of the blockage in your drain. We then address the root cause, always without damaging your pipes.
The steps for professionally unclogging a drain:
- Locating the blockage: Using the latest inspection equipment, we accurately map out the problem.
- Determining the correct unblocking method: Depending on the type of blockage, we opt for mechanical springs, high-pressure cleaning or chemical-free unblocking.
- Carrying out the unblocking: Our technicians remove all blockages thoroughly and safely, without damaging the drain.
- Drain testing and final inspection: After unblocking, we check for leaks and ensure the water flows away properly again.
- Advice and prevention: You will receive maintenance tips and we will advise you on any structural improvements.

The most common types of drainage problems in the home
Blockages occur in every room. In the Netherlands, we primarily encounter problems with shower drains, sinks, toilets, kitchen sinks, and outdoor sewers. Each type requires its own unblocking approach, in accordance with the protocols of the RIONED knowledge center.
- Toilet clogged: It's very annoying when you can no longer flush. In many cases, the cause is too much paper or non-biodegradable products.
- Sink clogged: Kitchen grease and food residue combine to form a tough plug. A spring or plunger helps, but professional flushing is often necessary.
- Shower or sink fills up: Hair, soap, and limescale buildup accumulates at the bottom of the siphon. Regular maintenance prevents most blockages.
- Outside sewer clogged: Subsidence, root growth, or downpours that carry debris cause problems, especially in the fall. Our pressure washer offers a solution.
What do you do when water flows back from the drain?
Backflowing water or overflowing drains almost always indicate a serious blockage downstream in your plumbing system. These kinds of problems are impossible to solve yourself. Acting quickly prevents damage and high costs. Water that can't drain away causes leaks all the way into the crawl space and can promote mold growth.
- Signal of sewer problem: Water backing up from the drain or toilet is a sign of a blockage in the main sewer line.
- Multiple drains clogged: If the kitchen, toilet and bathroom are experiencing problems at the same time, this is a reason to immediately call in a professional for an inspection.
- Odor nuisance: Persistent odors from drains not only indicate local blockages but can also point to cracks in the pipes or fractures in the ground.
- Urgently needed: In the event of an emergency flood, our emergency service provides solutions day and night, regardless of the time.

Techniques and products for drain unblocking
We work exclusively with certified methods and high-quality equipment. Mechanical spring machines, pumps, pressure washers, and endoscopic cameras are essential in the arsenal of every sewer specialist. Products like spring brushes, RIDGID pump kits, and biodegradable cleaning agents ensure a future-proof solution without damaging the environment or your pipes.
- Mechanical spring: Specially designed for stubborn indoor blockages. The spring is manually or mechanically guided through the pipe to loosen blockages.
- High-pressure cleaning: Using water pressure up to 200 bar, we flush dirt and grease from the system. Effective for major blockages in the main sewer.
- Camera inspection: This allows us to not only detect blockages but also any fractures or subsidence.
- Preventive measures: Biological enzymes or special siphon granules help keep pipes clean and odorless.
Preventing drainage problems: tips and maintenance
Daily maintenance of your drain significantly reduces the risk of future blockages. Follow these preventative steps to avoid problems:
- Use sieves: This will catch most of the dirt and hair immediately.
- Flush pipes thoroughly monthly: Run hot water with a little baking soda through it to rinse away grease and soap residue.
- Avoid chemical drain cleaners: These can damage existing pipes and are bad for the environment. Professional repair always yields better results.
- Have an inspection done annually: We offer maintenance contracts for recurring checks and rapid intervention in the event of problems.

Frequently asked questions
What are the most common causes of a clogged drain?
A clogged drain is usually caused by accumulated residue such as grease, hair, soap, or food particles that settle inside the pipes. In the kitchen, food scraps and grease are common blockages, while in the bathroom, hair and soap scum are the biggest culprits. Construction debris, excessive toilet paper, or limescale buildup can also cause blockages.
To prevent blockages, it's wise to regularly use a strainer in your sink or shower and not to pour grease down the drain. If you notice water draining more slowly, it's wise to address it immediately to prevent bigger problems. Want to learn more about effective solutions? Then check out our handy tips for clearing a sink blockage right away.
What is the best way to unclog a clogged drain yourself?
You can unclog a clogged drain yourself by using a plunger, pouring boiling water and baking soda into the drain, or using a snake. Always start by removing any visible debris and then try flushing the pipe with warm water and dish soap. Be careful with chemical drain cleaners; they can corrode pipes and are often harmful to the environment.
If this doesn't help or if the problem returns quickly, the blockage is either deeper or persistent, caused by grease or limescale, for example. Do you have a complex or recurring blockage? Then it's best to seek professional help. Our specialists at Ontstoppen.nl Address the root cause thoroughly with professional equipment and prevent permanent damage. Read more about professional help with clogged drains at home for more peace of mind.
When should you call a drain cleaning service for a clogged drain?
You should call a drain cleaning service if the problem persists after your own attempts, or if there's a complete blockage. If the water stops draining completely, multiple drains in your home become blocked simultaneously, or you notice a foul odor, you often have a serious blockage in the main sewer or deep within the pipes. Prompt intervention prevents water damage and unnecessary costs.
At Ontstoppen.nl Get immediate help within 24 hours, with fixed prices and an 8-week warranty. We use modern techniques like high-pressure jetting or spring machines.

What can you do to prevent a clogged drain in the future?
To prevent future clogged drains, regular maintenance is crucial. Flush your pipes occasionally with hot water and a natural mixture of baking soda and vinegar. Also, install drain filters in sinks and showers to catch hair, soap scum, or food scraps. Never flush grease, oil, or large food particles down the drain, as these easily accumulate in bends and traps.

This will prevent unpleasant surprises and keep your sewer system healthy. For smart prevention tips and maintenance, visit our page on unclogging drains without demolition.
