What can clog a drain?
A clogged drain has several causes. The most common causes are:
The number one cause of a clogged drain is an excess of waste residue that enters the drain with the sewage. Grease and food scraps get stuck to the inside of the sewer over time, which at some point clogs the drain.
Another way the drain can get clogged is by objects that accidentally get into the drain. This can include rubber bands, pins, cotton swabs, papers or other objects. These blockages are easily prevented by being extra vigilant about objects close to the drain. If the blockage is already in the drain, we are happy to help you unblock drains.
While showering, you lose hair. Over time, these hairs will accumulate in the drain, which can lead to a clog. This type of clogging is also easy to prevent by regularly removing hair from the drain.
Also, like sewage, soap scum sticks to the inside of the drain, which can lead to a clog. This can be the clogging cause in several drains.
Finally, the lime that water contains can also cause a drain blockage. Running water can leave lime residue in the sewer system, leading to an accumulation and blockage.
Are you suffering from a clogged drain? Choose a professional approach and have your drain unclogged by the certified technicians at RBNL. We assure you of 24/7 service, worry-free warranty and no unexpected additional costs!
When to choose to have your drain unclogged?
You can unclog the drain with a superficial clog yourself in several ways. You can use a plopper or buy a drain unblocker. It is often best to call in a specialist immediately for clogs.
Our professionals have the right knowledge and resources to solve various drain unclogs. In fact, unclogging the drain yourself can often make the situation worse. Usually the clog is too deep and there is a good chance of making the problem worse.
For example, it often happens that by taking the wrong approach or using the wrong tools, the clog is only maneuvered further down the drain. You can also cause damage and wear and tear to the drain. Therefore, have your drain unclogged by a specialist. We are happy to come and help you to ensure that the drain is professionally cleared and the water flushes properly again.

Tips to unclog small clogs yourself
Want to unclog your drain? Small blockages such as a shower drain with hair or a sink with soap residue can be solved by yourself. This is because these clogs are often located shortly behind the siphon. Below we have listed some ways you can solve small clogs:
First, you can try pouring buckets of water down the drain. When you see a whirlpool forming in the water, this is often the sign that the sewer connection is no longer clogged.
If not, you can try flushing the drain with boiling water and baking soda. Baking soda is a natural tool that can loosen and dissolve dirt in the drain. This is how you can unclog the drain.
Do you have a clogged drain due to grease residue? Like baking soda, dish soap works well against grease residue in a drain. Try unclogging the drain by flushing away grease residue. You can do this by pouring a bucket of hot water and dish soap down your drain. Let this soak in for half a day. Once the soaking time has passed, you can open the faucet to see if the water is flushing away again properly.
When these ways don't help, you can try unclogging the drain with materials such as a plopper or a plunger spring. Using this method unclogs most drains. However, wear and tear on the drain can occur if this method is used too often.
For unclogs located just behind the trap, you can also choose to disconnect the trap and clean it with water and baking soda. When unclogging, don't forget to place a bucket under the siphon to catch water and debris. This method of drain unclogging can be used for both sink and sink unclogging. With the sink, be careful not to use boiling water. This can crack the porcelain.

Tips to prevent a clogged drain
There are several ways you can prevent the drain from getting clogged with food particles, hair and other objects. We offer a few tips:
- You can put a strainer in front of each drain where the largest food particles remain. You can empty the sieve into the trash in due time. This prevents food particles from clogging the drain.
- You can also be careful that items such as pins and cotton swabs do not accidentally end up in the drain, which can lead to blockages.
- Shower drains and sinks can be cleaned regularly by removing stuck hairs and rinsing the drains clean with water and baking soda, reducing the chances of a clog.
- By preventing large amounts of food or toilet paper from ending up in the drain, you can also prevent a drain clog.
