A flusher can typically reach 100 to 150 meters into drains with standard equipment, but the range varies based on the diameter of the pipe, the number of bends, and the condition of the pipe system. Professional equipment with long hoses can reach further, while narrow pipes with many bends limit the range. This article answers the most common questions about the reach of a flusher and what affects how far the equipment can reach.
What is a car wash and how does it work?
A drain cleaning truck is a special vehicle equipped with high-pressure equipment that cleans drain pipes by spraying water at extremely high pressure. The truck has a large water tank, a powerful pump that creates high pressure, and long hoses with specialized nozzles that can be inserted into the pipe system. The water is sprayed out at such high pressure that it loosens grease, limescale, hair clumps and other things that have stuck to the pipe wall.
The system works by an operator inserting a flexible high-pressure hose into the drain pipe through an existing access point such as a sump or inspection hatch. The nozzle at the end of the hose has holes that spray water both forward and backward. The backward jets propel the hose forward into the pipe while cleaning the pipe wall. The forward water breaks up clogged clogs and pushes the debris further into the system.
The pressure varies from 100 to 300 bar depending on the condition of the pipe and the type of seal. Professional plumbers choose the right nozzle and pressure based on the pipe material to avoid damage. The method is effective for most types of clogged drains and provides a thorough cleaning that removes deposits that have built up over time.
How far does a flushing truck reach into the pipes?
Standard equipment on a flushing truck typically reaches 100 to 150 meters into drains under normal conditions. This range is for pipes of moderate diameter and without major obstructions. Professional equipment can have hoses up to 200 meters or more, but effective cleaning depends on several factors beyond just the length of the hose.
The diameter of the pipe plays an important role. In larger main sewer pipes of 150-200 millimeters, the flushing truck can reach further because the hose encounters less resistance. In narrower pipes of 50-75 millimeters, the range is significantly reduced. The number of bends and turns in the pipe system also limits how far the hose can be advanced. Each 90-degree bend creates friction and resistance that makes it more difficult to push the hose further.
Professional operators assess the design of the piping system before starting work. They may use cameras to inspect the pipes and identify problem areas. By choosing the right access point, they can often reach further into the system. Sometimes they must work from multiple points to cover the entire section that needs cleaning.
What affects how far the cleaning truck can reach?
Several factors limit how far the high-pressure washer can reach into the drain pipe. The diameter of the pipe is the most obvious factor. Small pipes create more resistance against the hose and reduce the reach compared to larger pipes. The material of the pipe also affects how easily the hose slides forward. Smooth plastic pipes provide less friction than rough concrete or cast iron pipes.
The number and angle of bends in the piping system is critical. Each bend or bend the hose must pass through significantly increases resistance. Sharp 90-degree bends are more difficult to pass than smooth bends. Older piping systems with many changes in direction can limit the range to only 50-70 meters even with professional equipment.
Existing seals and the condition of the pipes also play a role. A severe seal can stop the hose completely before it reaches its maximum length. Pipe breaks, jammed sections or heavy roots that have grown into the pipe create physical barriers. The thickness and flexibility of the hoses affect how easily they maneuver through the system. Thinner hoses reach further but can withstand less pressure.
Available water pressure from the vehicle also sets limits. When the hose becomes very long, the pressure at the nozzle drops. This reduces the cleaning effect even if the hose can physically be inserted further. Professional operators balance length against effective cleaning power.
What happens if the drain is further in than the flushing truck can reach?
When the problem is beyond the reach of the flushing truck, there are several alternative solutions. The most common approach is to find another access point closer to the problem area. Many properties have multiple manholes or inspection points along the drainage system. By working from a point further downstream or upstream, the plumber can reach areas that were inaccessible from the first point.
Special equipment with extra long hoses can be hired for situations that require a greater reach. Some professional plumbers have equipment that reaches 200-300 meters. Camera inspection is often used to pinpoint the exact location of the problem. This provides valuable information on whether flushing is the right solution or whether other methods are needed.
In some cases, digging is necessary to access the problem area. This is especially true for severe pipe breaks, stuck sections, or when roots have damaged the pipe. Digging allows the plumber to repair or replace the damaged section directly. Other times, mechanical cleaning with spirals can reach the problem when high-pressure flushing is not enough.
For very long stretches it may be necessary to work systematically from several points. The plumber flushes as far as possible from each access point until the entire system is covered. This takes more time but ensures thorough cleaning of the entire drainage system.
How do you know if you need a car wash or another solution?
High-pressure flushing with a flushing truck is the best solution when the drain is flowing slowly, smells bad or stops regularly. These symptoms indicate a build-up of grease, soap, hair and other organic material on the pipe wall. Flushing removes this effectively and provides long-lasting results compared to chemical agents that only provide temporary relief.
You probably need a drain cleaning service if water is standing in your drain or toilet, gurgling in your drain when you use water elsewhere, or if you have recurring problems even after trying simpler solutions. Older properties with pipes that haven't been cleaned for many years often benefit greatly from professional drain cleaning. This is especially true if several drains in the house are affected at the same time, indicating a problem in the main drain.
Other solutions may be better in certain situations. Simple seals near the surface can often be resolved with a manual coil or plunger. If the problem is caused by foreign objects such as toys or rags, mechanical removal may be necessary. In the case of pipe ruptures or severe structural damage, flushing will not help, and the pipes will need to be repaired or replaced.
Camera inspection can clarify which solution is best. This allows the plumber to see exactly what is causing the problem and choose the right method. Professional plumbers consider the symptoms, the age of the plumbing system, and past problems before recommending flushing or other measures.

Vanlige spørsmål
How much does it cost to rent a sewage cleaning truck?
The price for professional flushing typically ranges between 3000 and 8000 kroner depending on the scope of the job, the reach required and how long the work takes. Emergency calls at evenings and weekends usually cost more. Many plumbers offer a fixed price after an initial assessment, and it may be a good idea to ask if the price includes a camera inspection to identify the problem before flushing.
Can high-pressure washing damage my pipes?
When performed by professional operators with the right equipment and techniques, high-pressure flushing is safe for most pipe systems. Experienced plumbers adjust the pressure and select appropriate nozzles based on the pipe material and condition. Very old or already damaged pipes may be vulnerable, and a camera inspection will first reveal whether flushing is safe or whether the pipes should be repaired first.
How often should I have my drain pipes cleaned with a flushing truck?
For most homes, professional flushing every 3-5 years is sufficient to prevent buildup and clogs. Properties with older plumbing systems, high levels of grease buildup, or nearby large trees may benefit from more frequent cleaning every 1-2 years. Commercial buildings such as restaurants with high grease discharge should often have their drains cleaned annually or even more frequently to avoid problems.
Do I have to be at home while the car wash is working?
You usually don't need to be present for the entire job, but should be available at the start to show the plumber where the problem is and provide access to manholes or inspection points. If the work is only done outdoors from municipal manholes, many jobs can be done without you being at home. Discuss this with the plumber when you book, so you can agree on practical solutions.
What can I do myself to prevent the drain from clogging?
Avoid flushing grease, cooking oil and coffee grounds down the sink, use hair filters in drains and showers, and never flush wipes or hygiene products down the toilet. Regular flushing with hot water and a little dish soap can help keep your pipes clean. At the first sign of slow drainage, address the problem immediately before it develops into a full blockage that requires professional help.
Does a flushing truck work equally well on all types of drain pipes?
High pressure flushing works great on most modern pipe materials such as PVC, plastic and cast iron, as well as older concrete and ceramic pipes. The method is especially effective on smooth plastic pipes where the water can thoroughly clean the entire surface. Very old clay pipes or pipes with rough surfaces may be more difficult to get completely clean, but flushing will still remove most of the buildup and significantly improve drainage.
Can a water jet remove roots that have grown into the drain pipes?
High-pressure water jetting can cut through smaller roots and remove them from the pipe, but for extensive root ingrowth, mechanical root milling is often required first. After the roots have been mechanically removed, water jetting is used to clean away debris and deposits. If roots have damaged the pipe itself and created cracks, the pipes often need to be repaired or replaced to prevent the problem from recurring.
