You need a flush truck when sewage problems affect several drains at once, water flows slowly or comes up in other drains, or when you hear bubbling sounds from toilets and floor drains. Flush trucks are used to clear blockages in mains and larger sewer systems where conventional methods are not enough. We'll go through the main signs that show when you need professional flushing and how the process works.
What are the signs that I might need a vacuum cleaner?
Recurring blockages in several drains at the same time are the clearest sign that you need a flushing truck. When water flows slowly in the kitchen, bathroom and laundry room at the same time, or when water comes up in floor drains when you flush the toilet, it indicates problems in the main line. Bubbling sounds from the drains and persistent bad odors are also warning signs that should not be ignored.
Problems that require a flushing truck differ from ordinary blockages in that they affect several points in the property. A blockage in a single sink or drain can often be solved with simple methods. But when water starts to back up into lower drains when you're using higher ones, it's a blockage in the main.
Slow drainage throughout the property is another sign. If all the drains are emptying more slowly than usual, even after you've tried to clear them, there are probably build-ups in the main line that require high-pressure flushing. Grease, soap scum, hair and other deposits build up over time and create blockages that ordinary methods cannot reach.
You may also notice that problems come back shortly after clearing a drain. This shows that the root cause is further into the system. Roots from trees that have penetrated pipes, large accumulations of grease or collapsed pipes require professional assessment and flushing with a flushing truck.
What is the difference between regular sewer cleaning and a flushing truck?
Ordinary sewer cleaning uses manual spirals and tools to remove blockages in individual drains near the interior points of the property. High-pressure flushing is used for more extensive blockages in pipes, while flushing trucks are needed for blockages in mains and larger sewer systems that are further away from the property. Each method is suitable for different types of sewer problems depending on the location and severity of the blockage.
When a plumber comes to assess sewer problems, they often start by inspecting where the water is running slowly or stopping. For stoppages in an individual sink, basin or shower, a spiral fed into the drain is usually enough to break up the blockage. This works well for hair, soap scum and smaller accumulations near the surface.
High-pressure flushing is used when the blockage is deeper in the pipes or when several drains are affected. The equipment pumps water at high pressure through the pipes, breaking up grease, deposits and small roots. This method reaches further than manual tools while cleaning the inside of the pipes.
The flushing truck comes in when the problem is in the main line between the property and the municipal sewer system, or in larger properties with extensive sewer systems. The flush truck has more powerful equipment that can handle longer distances, larger pipes and more extensive blockages. It can also clear pipes up to several decimeters in diameter and reach hundreds of meters into the system.
Plumbers assess what approach is needed by asking questions about where the problems are occurring, how long they have been going on and whether multiple drains are affected. Sometimes camera inspection is used to pinpoint the exact location of the blockage before deciding on a course of action.
How does flushing with a flushing truck actually work?
Flushing with a flushing truck starts with technicians locating the problem by inspecting, and often camera scanning, the sewer lines. The high-pressure equipment of the flushing truck is then connected to the sewer system via an inspection hatch or suitable connection point. Special nozzles spray high-pressure water that breaks up and flushes away accumulations of grease, roots, deposits and other blockages while the water carries the material away.
The process starts with technicians identifying the location of the blockage. Camera inspection shows not only where the blockage is but also what caused it. Roots, collapsed pipes, grease build-up and other problems are clearly visible on camera, helping technicians choose the right nozzle and pressure for the job.
Once the flushing truck is in place, the high-pressure equipment is connected to the sewer system. A heavy-duty hose with a special nozzle is fed into the line. The nozzle has backward spray jets that propel the hose forward while flushing the inside of the line. The pressure can be adjusted depending on the material and condition of the line to avoid damage.
The high pressure water breaks up blockages and washes away material that then follows the water flow out through the system. For grease accumulations, the pressure dissolves the layer from the walls of the pipe. For roots, the water jet cuts through and flushes the material away. The process continues until the entire section is clean and the water flows freely.
The process varies depending on the type of property and sewerage system. In apartment buildings with complex systems, flushing may take longer and require access to multiple inspection points. In single-family neighborhoods, the system is often simpler but the lines may be longer. After flushing, technicians check that the water flows freely and that the problem is solved.
Can I solve the problem myself or do I need professional help?
You can handle simple sewer problems yourself with plungers, drain cleaners or manual spirals when the blockage is in a single drain near the surface. But mainline blockages, recurring problems or blockages affecting multiple drains always require professional help from plumbers with the right equipment. Attempting to resolve more serious problems yourself can worsen the blockage, damage pipes or cause flooding.
A plunger works well for simple blockages in toilets, sinks and drains where the blockage is close to the surface. Chemical drain cleaners can dissolve smaller accumulations of hair and grease, but use them carefully as they can damage old pipes and are dangerous to handle. Manual spirals that you buy in DIY stores reach a little deeper and can remove blockages in individual drains.
When to contact a plumber depends on the extent of the problem. If the same drain repeatedly clogs even though you've cleared it, the root cause is deeper in the system. If water comes up in other drains when you use one, the blockage is in a common pipe that you cannot reach with simple tools.
The risks of trying to solve serious sewer problems yourself are significant. You can push the blockage further into the pipe and make it harder to remove. Improper use of tools can damage the pipes and cause leaks in walls or under floors. Strong chemicals can react with materials in the pipes and create dangerous situations.
Problems that always require professional help include blockages that affect the entire property's drains, water backing up from floor drains, persistent bad odors despite cleaning, and situations where you suspect roots in the pipes. We have the equipment to locate and resolve these problems safely without damaging your sewer system. Call us on 08 40 24 240 when you are unsure if you can handle the problem yourself.
