What are the causes of blockages in the home?
Blockages often cause great frustration and can severely disrupt daily life. Drains such as those in the kitchen, bathroom, and toilet have to deal with everything you flush, from food scraps to hair and grease. According to the National Institute for Public Health and the Environment (RIVM), many problems arise because people do not fully understand what does and does not belong in their wastewater. As a result, sewer managers in municipalities such as Utrecht and Amsterdam are seeing an increase in blockages. By understanding where the risks lie, you can prevent a lot of misery and costs.
- Do not flush grease and food residue: Liquid fat solidifies as soon as it cools and adheres to the inside of pipes. Over time, a thick layer forms that obstructs the flow.
- Preventing hair in the shower and sink: Hair, combined with soap residue, forms a stubborn plug. As a result, the drain becomes increasingly narrow, leading to a blockage.

Keep kitchen drain clean: Minimize risk of blockage
One of the places where blockages occur quickly is the kitchen. Dishwasher capsules, oil, coffee grounds, and food residue, in particular, cause problems with the drain. Waternet notes that small daily habits have a major impact.
- Prevent coffee grounds in the sink: Coffee grounds easily collect in bends of the pipe, causing blockages to occur more quickly.
- Use a sieve: A strainer in the sink catches food scraps. This prevents them from entering the drainage system.
- Collect fat separately: Always pour used frying oil or cooking fat into a sealed bottle. Hand it in at special collection points of your municipality or supermarket.
- Do not rinse with cold water: Grease remains liquid if you rinse with hot water. This prevents buildup in your pipes.
Bathroom rules: Keep other rooms clog-free
Wastewater in the bathroom contains hair, skin oils, soap residue, and sometimes even toys or toiletries. By taking a few simple measures, the risk of blockages is greatly reduced.
- Place a grate over the drain: This is how you prevent hair and larger particles from ending up in the sewer.
- Use only toilet paper: Never flush wet wipes, tampons, or sanitary pads down the toilet. They do not break down and easily get stuck in pipes.
- Check the siphon regularly: Clean siphons (Swan neck under the sink) monthly so that accumulated residue does not have a chance to form a blockage.
- Rinse regularly with hot water: Hot water dissolves grease, soap, and dirt residues so that they reach the main sewer more easily.
Regular maintenance prevents clogging
Prevention is always better than cure. By regularly cleaning your pipes and sewer, you ensure that everything continues to flow smoothly. Incorporate these steps into your household routine at least every quarter.
- Check all drains in the house for flow: If you notice that water is not draining properly somewhere, address it immediately.
- Thoroughly clean the shower drain and grate: Remove hair and soap residue with every cleaning.
- Use natural-based cleansers: Soda and hot water help dissolve residue without damaging your pipes or the environment.
- Have the sewer system inspected preventively every year: A specialized company like Ontstoppen.nl detects emerging problems in time.
- Check downspouts and gutters: Leaves and debris can clog the rainwater drain and cause flooding in the basement or crawl space.

10 practical tips to prevent blockages and protect your home
Through conscious choices and habits, you make your home less vulnerable to clogged pipes step by step. Expert Pierre Faure from the University of Lyon advocates for an integrated approach to both maintenance and behavior to combat blockages sustainably.

Frequently asked questions
1. What are the main causes of blockages in the home and how can you prevent them?
One of the most common causes of blockages in the home is flushing the wrong materials down the drain, such as wet wipes, grease, and food scraps. By being mindful of what you flush down the toilet, sink, or shower drain, you can prevent many problems. For example, use strainers in the sink and shower drain to trap hair and larger debris, and always throw grease and oil in the trash can instead of flushing them down the sink.
Regular maintenance of your pipes is also essential. For example, flush hot water through your drains once a week so that grease and soap residue build up less quickly. Do you notice that you are dealing with blockages more frequently? Then consider seeking professional advice.

2. Which 10 practical tips make my house less vulnerable to blockages?
To make your home less vulnerable to blockages step by step, you can easily integrate daily and periodic habits into your routine. Consider: regularly checking your siphons and drains, using strainers in the kitchen and bathroom, not flushing food scraps and grease down the sink, removing hair and soap residue from shower drains, flushing with hot water occasionally, and being mindful of what you flush down the toilet and drain. Additionally, it is smart to install water-saving toilets and taps and to have the drain pipes inspected preventively by an expert.
By following these steps, you not only reduce clogging problems but also extend the lifespan of your pipes. Would you like to learn in detail how to easily apply these tips and what the benefits are? Then take a look at drain protection tips for more background information.
3. What is the best way to maintain my toilet myself to prevent blockages?
Prevention is better than cure, especially when it comes to the toilet! Only flush toilet paper and human waste, and be sparing with the use of wet wipes, sanitary pads, or tampons, as these often lead to blockages. Regularly check that the water drains properly, clean the siphon housing, and give your toilet a maintenance clean with hot water once a month – this helps limit limescale and grease buildup.
Is your toilet draining slowly or making gurgling noises? Then take action before the blockage gets worse. Do you need professional help immediately, or are you curious about methods for unclogging a toilet without damaging the pipes? Check out the options at professional toilet maintenance.
4. Why does periodic drain maintenance help prevent blockages and how do you go about it?
Because grease, soap, and hair slowly accumulate in drainpipes, blockages usually do not occur suddenly but build up over weeks to months. By regularly flushing your drains periodically with hot water or eco-friendly cleaners, you prevent dirt from sticking. Be sure to also check the siphons and expose them regularly to remove caked-on residue.
Implementing preventive maintenance such as camera inspection or professional flushing ensures that pipes remain structurally clear, especially in older homes or those with heavy use. Do you want to know how we Ontstoppen.nl Perform such an inspection and what it brings you? Discover the details of professional maintenance at preventing stubborn drainage problems.
5. What signs indicate an impending blockage and how do you act quickly?
Pay close attention to signals such as slow-draining water, gurgling sounds in the pipes, or an unpleasant sewer smell, as these are often the first signs of a developing blockage. Acting quickly by cleaning siphons, flushing with hot water or baking soda, and using a plunger can prevent a lot of trouble at this stage.
If these measures do not help, or if multiple drains are slow at the same time, there is often a deeper blockage. Do not wait until the water stops draining completely, but call in a specialist quickly in that case to prevent greater damage. Hopefully, with these insights, you can keep your home in top condition! Do you want to know how a professional drain cleaner intervenes quickly and effectively for clogged drains?
