Have the drain cleaned - what to do when nothing drains?
A pipe blockage rarely occurs suddenly. It usually announces itself over a longer period of time. It often begins quite harmlessly: the water drains more slowly. A slight odor rises. You may not think anything of it at first. But before you know it, the drain is completely blocked. Now what?
This guide shows you how to recognize blocked pipes at an early stage, gives a realistic assessment of popular household remedies and explains when professional help is needed.
Causes of a pipe blockage: Why do drains actually block?
A blocked drain often has simple causes, which can usually be traced back to everyday household use. It is not always immediately obvious where the problem is coming from. In the kitchen, grease builds up and mixes with leftover food. In the bathroom, it is hair, soap residue and cosmetic products that clog the drains. And sometimes it is simply unfavorable pipe routing that encourages the whole thing. The most common reasons for blocked pipes are
- Grease and oil deposits: Food residues and grease solidify during cooling and stick to the pipe walls.
- Hair and soap or cream residue: They form tough deposits and stubborn lumps, especially in the bathroom.
- Solid residues: Food residues, coffee grounds or sand collect in arches and bottlenecks.
- Foreign body: Wet wipes, hygiene products or cat litter swell up and block the pipes.
Some of these risk factors can be influenced by correct behavior in everyday life, others (especially structural problems) cannot. You can find an overview of the most important tips for preventing blocked drains in our article «Drain blocked? - Causes, prevention and home remedies».
If you have the feeling that there is already a problem, you should not hesitate to have your drain professionally cleaned. As a general rule, it is better to react too early than too late to avoid the costly consequences of a blocked pipe, such as water damage or mold growth.
How can you recognize a blocked drain? Recognize early warning signs
The earlier a pipe blockage is detected, the easier it is to avoid consequential damage. You should therefore look out for the following warning signals:
- The water drains more slowly than usual. This problem indicates deposits or blockages in the pipe.
- The drain gurgles. Even if the water is still draining, gurgling noises indicate an incipient blockage. It occurs when air bubbles are forced upwards in the pipe due to a blocked water flow.
- The drain smells unpleasant. Organic residues and dirt accumulations that lead to clogged pipes also cause bad odors.
If these warning signs appear, you can first resort to home remedies for pipe cleaning and try to loosen light deposits. If there is no improvement or the problems are recurring, the pipes need to be cleaned by a specialist company.
Background information on professional pipe cleaning: What types of blockages are there?
Depending on the cause, location and severity, blockages differ significantly - and so do the appropriate measures to eliminate them. A rough distinction can be made:
- Superficial constipation:Â Usually easily accessible, often in the siphon. Can often be solved with household remedies or a coil.
- Deeper pipe blockage:Â Located deeper in the pipe system. Only professional means such as high pressure or motorized spirals can usually help here.
- Incrustations or deposits:Â These build up over years, mainly due to limescale, grease and soap residue. You often only notice them when almost nothing works anymore.
- Foreign body: Toys, rags or jewelry that (often accidentally) end up in the drain. In these cases, the only thing that usually helps is a Camera inspection.
Cleaning the drain: What can you do yourself?
You can counteract minor blockages that are not too deep in the pipe system with household remedies. Please note that not every popular household remedy is equally effective or helps in every case:
- Clean the siphon:Â With sinks or washbasins, you can often unscrew and clean the siphon yourself. Be sure to place a towel and a bowl underneath.
- Use a suction cup: A plunger can help to loosen blockages in the pipe. The up and down movement of the wooden stick and the suction effect of the bell create alternating negative and positive pressure, which can loosen small pipe blockages.  Â
- Home remedies (e.g. baking powder/soda and vinegar):Â These common household remedies help with light or fresh deposits, but not with solid blockages or deep-seated blockages.
- Drain cleaner:Â Numerous chemical drain cleaners are available on the market. But be careful: these cleaners can deform or damage metal and plastic pipes. They are also not environmentally friendly due to their ingredients.
Especially with stubborn deposits and deep-seated blockages, household remedies can do more harm than good. If nothing helps, you should stop trying and call in a specialist company at an early stage. This will prevent major damage and save you money.

When is it necessary to have the drain professionally cleaned?
Professional pipe and sewer cleaning is required at the latest when there are recurring or persistent problems with blocked drains and pipes. Even if you are unsure where the cause of a blockage lies, a camera inspection can be helpful.
Specialist companies for pipe and sewer cleaning offer quick help with:
- blocked drains (kitchen, bathroom, WC)
- Overflowing washbasins or shower trays
- unpleasant odors from the drain
- Regular maintenance to avoid emergencies
As soon as there are visible or noticeable restrictions in the drainage of water, professional cleaning is the most sensible solution to prevent consequential damage, reduce costs in the long term and restore the functionality of the entire drainage system.Â
As a rule, private households should schedule professional pipe cleaning approximately every 2 to 3 years. This is especially true for houses with old pipes and repeated problems with poorly draining water or odors. For apartment buildings and commercial buildings, an annual inspection is advisable.

How does professional pipe cleaning work?
Specialist pipe and drain cleaning companies use modern techniques and processes that are not available to end users. One example of a targeted cleaning technique is high-pressure flushing: a special hose is fed through the drain pipe at high water pressure to loosen stubborn deposits such as grease, limescale or embedded residues and flush them out of the pipe network. This largely restores the original pipe cross-section and future blockages have less surface area to build up.
A cleaning spiral is used for localized blockages (such as in the siphon or at narrow pipe bends). This is inserted into the drain pipe and picks up obstructions, breaks them up and pulls them out. This technique is particularly useful if the blockage cannot be removed using household remedies.Â
Camera inspection is also becoming increasingly important. A tiny camera system is inserted into the pipe and transmits live images of the inside of the pipe network. This makes it possible to locate damage, such as cracks, pipe displacement or root ingrowth, and the exact position of the blockage can also be seen. This method is particularly important for recurring problems where simple cleaning is not enough, or if there is suspicion of major damage to the pipe.
Frequently asked questions
Having drains cleaned in apartment buildings: Who pays for drain cleaning - the tenant or the landlord?
Who is responsible for a blocked pipe and therefore the cost of pipe cleaning? This question comes up again and again, especially in apartment buildings. The basic rule is:Â
- If the blockage is within the tenant's own four walls, i.e. in the area of the siphon or the apartment drain, the tenants are usually responsible themselves.
- If the cause lies deeper (i.e. in the downpipes or in the main drain of the building), the landlord or the management is usually called upon.
Who bears the costs for drain cleaning depends on the individual case. If there is a structural defect, the landlord usually bears the costs. In the event of improper use (e.g. by dumping wet wipes down the drain), the tenant is liable. A camera inspection helps to clearly identify the cause of the blocked drain.
What does professional drain cleaning cost?
The cost of professional drain cleaning depends on the location, the effort involved and the technology used. Smaller jobs are usually done quickly and are correspondingly inexpensive. For deeper-seated problems or heavy incrustations, it can be a little more time-consuming. As a rule, the cost of pipe cleaning is between CHF 180 and 350 per job. In the case of deep-seated blockages or limescale deposits in the drain, additional costs may be incurred for special technology or camera inspections.
With Kanalhelden, you benefit from transparent prices with no hidden fees. There is a clear assessment before every job and no hidden costs. In an emergency, we are available around the clock.
"A blocked drain is more than just a nuisance - it's a warning signal. If you wait too long, you often pay twice."
- Kanalhelden AG
When is a camera inspection useful?
If the blockage cannot be localized, if the same spot keeps causing problems or if it is an old pipe system, a camera inspection is an important tool for identifying the problem. A camera-supported analysis can not only save time, but also prevent unnecessary chiselling.

Frequently asked questions
What to do if the drain is blocked?
If the drain is blocked, simple household remedies often help. Pour hot water down the drain and try using a plunger. Slight drain blockages can also be cleared with vinegar and baking soda. In the case of heavy deposits, it is advisable not to use strong pipe cleaners, as these can make plastic pipes brittle and corrode metal pipes. Instead, contact a specialist company.
How do hard deposits form in the drain pipe?
Hard deposits in the drain are caused by a combination of grease, oil, soap residue, limescale and food residue that build up in the pipes over the years. Old drains with a rough inner surface are particularly affected. These deposits harden over time and cause the drain pipe to become completely blocked. Only professional pipe cleaning can remove them permanently.
Who pays for pipe cleaning - the tenant or the landlord?
Who bears the costs for drain cleaning depends on the individual case. If there is a structural defect, the landlord usually bears the costs. In the event of improper use - for example, if wet wipes have been discharged into the drain - the tenant is liable. A camera inspection helps to clearly identify the causes of the blocked drain.

How can I prevent future blockages in the drain?
To prevent a blocked drain. Avoid disposing of grease, leftover food, toiletries or wet wipes down the drain or toilet, as they often lead to stubborn deposits. Flush your drains regularly with hot water to loosen fresh residues in the pipes. Initial blockages can often be cleared with a plunger. We also recommend professional maintenance every two to three years to prevent major problems at an early stage.
