The root cleaning truck is an effective remedy for tree roots in drain pipes. When roots have penetrated the sewer system, the cleaning truck uses high-pressure water with specially designed nozzles that cut and wash away the root masses. The method works well against most root problems, but serious damage may require additional measures. TV inspection before and after treatment ensures that the job is thoroughly done.
What are roots in pipes and why is it a problem?
Tree roots enter drain pipes through small cracks, joints and loose connections. The roots actively seek out moisture and nutrients found in the wastewater. Once they have found their way in, they grow rapidly, filling the pipe from the inside.
The problem worsens over time because the roots trap grease, paper, and other materials that come with the wastewater. This creates clogged drains that can cause sewage to back up into the house. In the worst case, the root masses can cause structural damage to the pipe system itself, requiring costly replacement.
Root problems are especially common in older homes where the drain pipes are made of clay or concrete. These materials develop cracks with age, and the joints between the pipe sections become leaky. If you have large trees near your drain lines, the risk increases significantly. Poplar, willow, and ash are known for their aggressive root systems that actively seek out drain pipes.
How does a flushing truck work against roots in drain pipes?
The flushing truck uses high-pressure water with a pressure of 100-200 bar to remove roots from drain pipes. The water is forced through specially designed nozzles that both cut the roots and rinse away the root remains. The combination of high pressure and the right nozzle type means that even thick root systems can be removed effectively.
The process usually starts with a TV inspection of the pipe. This allows you to see exactly where the roots are, how extensive the damage is, and whether there are any structural problems. Based on the inspection, the plumber selects the correct nozzle type and adjusts the pressure to the condition of the pipe.
During the actual flushing, the hose is inserted into the pipe from an inspection point or sump. The nozzles spray water backwards with great force, which both propels the hose forward and loosens the roots. The root masses are flushed out of the system along with the water. After the treatment, a new TV inspection is often performed to confirm that all roots have been removed and that the pipe is clean.
What types of nozzles are used to remove roots from pipes?
Root cutting nozzles have sharp metal edges or blades that cut through the root mass. These nozzles are designed specifically to deal with dense root systems and act as a kind of rotating cutter inside the pipe. They are most effective against thick, dense root masses that have grown large over time.
The rotating head is another common type of nozzle that rotates under high pressure. The rotation combined with water jets causes the roots to both cut and tear loose from the pipe wall. This type is well suited when the roots have firmly attached themselves to the inside of the pipe.
Backward jets are standard on most flushing nozzles. The water jet shoots backwards with great force, which provides propulsion to the hose while loosening the material in front of the nozzle. Different nozzle sizes are adapted to the diameter of the pipe, from small 50 mm pipes to large 200 mm drain lines. Choosing the right nozzle depends on the root problem, the pipe size and the pipe material.
How effective is a car wash against major root damage?
Pipe flushing by a pipe cleaner effectively addresses most root problems, from small root fibers to medium-thick root systems. The method works best when the pipe itself is intact, and the roots have only grown inside the cavity. In such cases, the pipe cleaner can completely remove the root masses and restore normal water flow.
In very extensive root damage where the roots have broken through the pipe wall or deformed the pipe, the flushing truck has its limitations. If the pipe is crushed or collapsed due to root pressure, high-pressure root flushing will remove the root masses but will not repair the structural damage. In such situations, you must consider more extensive solutions.
Excavation and replacement of the damaged pipe section is necessary when the pipe is severely damaged. Relining is a less invasive option where a new pipe is pulled into the old one without digging. The TV inspection before treatment reveals the severity of the situation, so you get the right solution from the start. For moderate root damage drains, a flushing truck is usually completely sufficient.
Can roots grow back after car wash treatment?
Yes, the roots can grow back because the flushing truck removes the symptoms but not the cause of the problem. If there are still cracks, loose joints or holes in the pipe, new roots will find their way back in. The rate of regrowth depends on the type of wood, the season and the availability of moisture in the pipe.
Fast-growing trees like willow and poplar send out new root shoots quickly after the old ones are removed. During the growing season, you may find that the problem returns within one to two years. Slower trees give you more time before the roots become a problem again. The condition of the pipe also plays a role – the more entry points the roots have, the faster they will return.
Preventative measures reduce the risk of recurring root problems. Regular drain cleaning with a drain cleaning truck every two years keeps roots under control before they become a major problem. Root barriers can be installed around drain lines in areas with a lot of trees. The most permanent solution is pipe renewal with relining or replacement with tight, modern pipes that roots cannot penetrate.

Vanlige spørsmål
How much does it cost to remove roots from drain pipes with a flushing truck?
The price varies depending on the extent of the problem, pipe length and availability, but is typically between 5,000-15,000 NOK for a standard treatment. TV inspection usually costs 3,000-5,000 NOK extra, but is important to ensure proper treatment. In case of extensive root damage or the need for relining, the costs may be higher, while preventive annual flushing is often less expensive.
How long does it take to remove roots with a water jetting truck?
A standard flush truck treatment usually takes 2-4 hours including TV inspection before and after. Simple root problems can be solved more quickly, while extensive root masses in long pipe runs can take a full working day. The availability of inspection points and sumps also affects the time spent.
Can I prevent roots from penetrating the drain pipes myself?
Yes, there are several preventive measures you can take. Avoid planting trees with aggressive root systems (such as willow, poplar and ash) closer than 10 meters from sewer lines. Ensure regular inspection and maintenance of the pipe system, especially if you have older clay or concrete pipes. Consider installing root barriers along sewer lines in areas with a lot of vegetation, and schedule preventive flushing every 2-3 years if you have trees nearby.
Does high-pressure flushing damage the drain pipe itself?
Professional flushing with the right pressure and nozzle type does not normally damage the pipe. Experienced plumbers adjust the pressure according to the pipe material and condition – older clay and concrete pipes can withstand lower pressure than modern plastic pipes. TV inspection before treatment reveals any weak points, so the plumber can adjust the method. If the pipe is already severely damaged or cracked, there may be a risk, but then the inspection will reveal that other solutions are necessary.
What are the signs that I have roots in my drain pipes?
Common signs include slow drains that gradually get worse, repeated blockages in the same spot, and gurgling sounds from the drain. You may also experience unpleasant odors from the drain, sewage backflow from heavy water use, or the toilet not flushing properly. If you have large trees near your house and older drain pipes, you should pay extra attention to these symptoms and schedule a TV inspection if you suspect something is wrong.
Is it better to remove roots at a certain time of year?
Root problems should be addressed as soon as they are discovered regardless of the season, but the spring season is often favorable for preventative treatment. In winter, tree growth is minimal, allowing more time for regrowth to begin. Avoid waiting until the growing season is in full swing (late spring/summer) if you can, as roots grow fastest during this period and the problem can escalate quickly.
What is the difference between a flushing truck and mechanical root milling?
A water jet uses high-pressure water and special nozzles to cut and flush away roots, while mechanical root milling uses a rotating metal spiral with cutting blades. A water jet is less invasive, cleans the pipe more thoroughly, and reduces the risk of damaging the pipe. Mechanical milling may be necessary for extremely dense root masses, but often leaves root fibers that the water jet must remove afterwards. Many professional plumbers prefer a water jet as their first choice because of its efficiency and thorough cleaning.
