A professional drain cleaner typically uses between 100 and 200 bar of pressure (1450-2900 PSI) to effectively clean drains. This high pressure is necessary to remove stubborn blockages, grease and other deposits that block the pipes. The pressure is adjusted according to the pipe material and the extent of the problem, and is far more powerful than normal household water pressure, which is around 3-5 bar.
What is a car wash and how does it work?
A drain cleaning truck is a specialized vehicle equipped with a high-pressure pump, large water tank, and special hoses to clean drain systems. It works by sending extremely high-pressure water through the pipes, which loosens and flushes away deposits, grease, and other materials that block the drain.
The flushing truck consists of several components that work together. The large water tank can hold several thousand liters of water, while the high-pressure pump creates the powerful pressure needed. Special hoses with rotating nozzles are inserted into the drain pipe, and these nozzles spray water in all directions as they move forward in the pipe. This loosens deposits and flushes them out of the system.
Many modern drain cleaning trucks also have camera equipment that allows the pipes to be inspected both before and after cleaning. This helps the technician identify the problem and confirm that the job has been completed. The combination of high pressure and the right equipment makes drain cleaning trucks extremely effective for both acute blockages and preventative maintenance of drain systems.
How much pressure does a professional car wash actually use?
Professional drain cleaners typically operate at pressures between 100 and 200 bar , which is equivalent to 1450 to 2900 PSI. This level of pressure is necessary to break up stubborn deposits, remove grease residue, and clear out roots that have penetrated drain pipes.
The pressure is adjusted based on several factors. Older ceramic or cast iron pipes can handle high pressure well, while newer plastic pipes require more careful handling to avoid damage. The technician adjusts the pressure based on the pipe material, the condition of the pipe, and the severity of the problem. For regular household drains, 100-150 bar is often used, while heavier commercial installations may require up to 200 bar.
To put this into perspective: typical water pressure in a home is around 3-5 bar. A car wash uses 20-40 times more pressure than what comes out of your tap. This huge pressure difference is why professional equipment can clear blockages that regular methods can't.
The amount of water is also important. A water jetting truck delivers not only high pressure, but also a large amount of water, often 50-100 liters per minute. The combination of high pressure and large amount of water provides effective cleaning that both loosens deposits and flushes them completely out of the system.
What is the difference between a pressure washer and a regular high-pressure washer?
A professional pressure washer has higher pressure, larger water flow and specialized nozzles compared to regular home pressure washers. While a regular pressure washer delivers 80-150 bar, pressure washers operate at 100-200 bar and have equipment specifically designed for drain cleaning.
The main difference lies in the nozzle technology . Pressure washers use rotating nozzles that spray water backwards and to the sides while being pulled forward in the pipe. This creates a self-cleaning effect that both loosens deposits and rinses them out. Conventional high-pressure washers only have forward-facing nozzles, which are not suitable for drain cleaning.
Pressure washers also have much longer hoses, often 50-100 meters or more, which reach deep into the sewer system. A standard pressure washer rarely has more than 10-15 meters of hose. The water flow is also significantly higher on professional equipment, which is necessary to flush away large amounts of waste and deposits.
Using a regular pressure washer on drains is actually risky. Without the right nozzle and technique, you can push deposits further into the system instead of removing them. You can also damage pipe seals or cause leaks if the pressure is directed incorrectly. Professional technicians know how to match the pressure and equipment to each individual drain system.
When should you call a plumber for sewer problems?
You should contact a professional drain cleaning service when your drain is draining slowly, stopping completely, has a foul odor, or is making gurgling sounds from the drains. These signs indicate that the problem is too serious to be solved with common home methods like drain cleaners or plungers.
Slow drains that don't improve after simple cleaning are a clear sign. If the water sits in the sink, shower or bathroom for a long time, it indicates blockages deeper in the system. Recurring problems even after you've tried to solve them indicate a more extensive blockage in the pipes.
Bad smells from the drain can mean that grease, soap scum or organic matter has accumulated in the pipes. Gurgling sounds when you flush water indicate that air is not being able to move freely in the drain system, which is often caused by partial blockages. If several drains in the house are affected at the same time, the problem usually lies in the main drain and requires professional treatment.
Preventative maintenance is also important. Many property managers have their drains professionally cleaned every 2-3 years to avoid acute problems. This is especially relevant for older buildings, restaurants and businesses with a lot of greasy waste. Regular high-pressure cleaning extends the life of the drain system and reduces the risk of costly emergency drains.

Vanlige spørsmål
Can high pressure from the water jetting damage my drain pipes?
When the job is done by a professional technician, the risk of damage is minimal. Experienced technicians adjust the pressure based on the pipe material, age and condition of the pipe. Modern plastic pipes are treated with lower pressures (100-120 bar), while older cast iron or ceramic pipes can withstand higher pressures. Damage usually only occurs if the pipes are already in poor condition or if inexperienced people use the equipment incorrectly.
How long does it take to flush a sewage system?
For a typical household drain, the job usually takes 1-2 hours, depending on the extent of the problem and the accessibility of the drain system. Simple blockages can be cleared in 30-45 minutes, while more extensive cleaning of the entire drain system can take up to 3-4 hours. If the technician uses pre- and post-inspection cameras, additional time is added for thorough documentation.
How much does it cost to rent a sewage cleaning truck?
The price varies from 3000 to 8000 kroner depending on the complexity, time and location of the job. Emergency calls in the evening, night or weekend cost more than scheduled daytime assignments. Simple blockages are in the lower price range, while extensive system cleaning with camera inspection costs more. Always ask for a quote before the work starts, and check whether the price includes any additional costs.
How often should I have my sewage system flushed preventively?
For regular homes, preventive flushing is recommended every 3-5 years, while older buildings and properties with known problems should be flushed every 2-3 years. Restaurants, canteens and businesses with a lot of greasy waste should flush their drains annually or more often. Regular maintenance prevents costly acute blockages, extends the life of the pipes and ensures that the drainage system functions optimally.
What should I do to prepare before the cleaning truck arrives?
Make sure the technician has free access to all relevant drains, sumps and inspection points in the drainage system. Remove any objects around the work area and inform the technician of any known problems or previous repairs. It is also a good idea to avoid using the drain in the hours before flushing so that the technician has a clear picture of the problem. Knowing where the main drain or sump is located will make the job go faster.
Can I flush the drain myself with rented equipment instead of calling in professional help?
It is strongly discouraged to rent professional flushing equipment without experience and training. Improper use can cause serious damage to pipes, seals, and sumps, and you may push deposits deeper into the system instead of removing them. Professional technicians are trained to select the correct nozzle, adjust pressure, and identify the condition of the pipe. For simple problems, you can try common home methods first, but leave high-pressure flushing to the professionals.
Will flushing solve all types of drain problems?
High-pressure flushing will solve most blockages caused by grease, soap scum, hair and organic matter, but not all problems. If the pipe is collapsed, broken or has serious structural damage, repair or replacement is required. Roots that have penetrated through cracks can often be removed with flushing, but the cracks themselves must be sealed afterwards. Camera inspection reveals whether the problem can be solved with flushing or whether other measures are required.
