How is the flushing of pipelines and sewerage wells done?
Recently, various tips and recommendations for the care of sewer networks are often found. There are questions that interest me the most.
- How do I know if my main sewer line is clogged?
- Why does my main sewer line keep clogging up?
- How often should pipes be flushed?
- Can I flush the storm sewer myself?
- How do I get rid of roots in my sewer line?
The most effective way to flush storm sewer systems is the hydrodynamic method, the high pressure flushing method. Now hydrodynamic flushing of pipelines for various purposes is considered the most optimal and efficient. Thanks to her, the pipes will be completely cleared of blockages and will be able to perform their functions for a long time.
Small blockages can be eliminated with the help of available tools that are sold in specialized stores, but large ones can completely block the pipes and lead to an emergency. At the moment, hydrodynamic flushing is considered the best method for flushing the sewage system, since it removes blockages in the most gentle and effective way.
What is hydrodynamic pipe flushing
It is a mechanical treatment of the inner walls of the pipe using a jet of water supplied under high pressure (100-200 atmospheres). The walls of the pipes seem to be cleaned by a huge stiff brush. When the flushing is completed, all the sediment on the pipes will disappear.
The installation consists of a water compressor, a drive powered by electricity or a diesel engine, a hose and a handpiece equipped with a nozzle. The nozzles are equipped with direct and reverse acting nozzles.
At what diameter of the sewer pipe can hydrodynamic flushing be done?
Hydrodynamic flushing is equally effective for cleaning domestic and industrial pipelines with a diameter of 50 to 1000 mm. The strong pressure of water will relieve the pipeline of any blockages.
Using the hydrodynamic method, you can flush the risers in a house or apartment. But for domestic sewage, the mechanical method of cleaning pipes is more often used. This is due to the fact that the hydrodynamic equipment is large and it will not be convenient for them to flush inside the room. For internal sewerage, a mechanical cleaning method is more often used.
The hydrodynamic method of flushing pipes, one of the most effective methods that will help get rid of sewer blockages. This method is used for external sewage systems, it is considered an effective method for cleaning storm sewer systems. With this method, metal, plastic and ceramic pipes can be washed.
Diameter of pipes is 50-1000 mm, depending on the nozzle. The pipeline is supplied with a water pressure of 180-200 bar. Water consumption – 50-230 liters / min. The maximum working length is 100 meters.
Hydrodynamic flushing of a sewer pipe is one of the most effective methods for removing blockages in pipes.
There are many different nozzles that can be used to flush different pipe sizes. From the smallest 50 mm to large pipelines.
This method is an approach for flushing pipelines made of a wide variety of materials, including plastic.
For internal sewerage, no one uses hydrodynamic flushing, since the equipment is voluminous. This method is used for flushing outdoor and storm sewers. For the internal sewage system – electro mechanical drain cleaning.
We clean the sewage system in the house once every 3 years – I do the cleaning myself using a plumbing cable. As for the storm sewer system, we turn to a specialized service. They flush the pipeline with a hydrodynamic method, wash away any blockages under high pressure.
If you do not understand why your sewage system is constantly clogged, I recommend making a diagnosis using special equipment.
We, too, very often clogged the storm pipe – it was the diagnostics of the sewage system that helped to find the place of the blockage.
I have a similar question, but it concerns the sewage system in the apartment. The sewage system in the bathroom is constantly clogged, especially in the bathroom itself, when someone is washing in the bathroom, the water is drained with great difficulty. The sink is the same. I’m tired of cleaning, for the third time in a year I have been cleaning pipes. The pipe itself is 50 mm in diameter – it goes through the bathroom to the kitchen. All devices are directly connected with straight pipes, flexible hoses and flexible siphons are not used. The slope of the sewer is normal, I checked it with a laser level. I think the pipe diameter can change 75mm for example. What could be the reason for the clogging of the sewer? Hair is clogging, or maybe all the fats come from the kitchen and also clog the pipe?
I am planning to redo the sewerage system, as I don’t really want to clean it every month.
Pipes with a diameter of 50 mm, absolutely normal for apartment sewage!
You have several options for solving sewage problems:
Have you always had a problem with the sewerage pipeline or has it appeared recently?
Previously, there were no such problems with the sewerage system. A plumber has already come to us and cleaned the pipeline, but this did not help solve the problem. Water drains very slowly.
If your sewer was working properly before, most likely the problem is a blockage. You need to find a good specialist to flush all the pipelines.
The water flows down slowly as the pipe diameter has decreased. If you say that this problem has not been observed before. So you have a clogged sewer.
You should try mechanical cleaning of the pipes, or you can try using a plumbing cable.
Your riser may be clogged. And the plumbers who cleaned the pipes did not reach the very blockage.
Do your neighbors have similar problems with sewer blockages?
We have a very dirty sewer well and storm pipe in our country house. Can I somehow independently clean the storm sewer system?
Sewer wells get dirty and clogged, in order to prevent the entire sewer system from failing, it is important to carry out preventive work on time to remove accumulated debris from the drains.
In order to make high-quality flushing of the walls of the sewer well, you need to use special equipment. Which, under a high pressure of water, will wash away all impurities.
There are special nozzles for flushing collectors and sewer wells. In order to get the best effect, special chemicals are sometimes added.
Is it possible to flush plastic sewer pipes using the hydrodynamic method?
In our house, the risers are made oh plastic, they are already old, you need to clean them. But there are doubts that this can be done using the hydrodynamic method.
How safe is it for plastic pipelines?
How to remove roots from a sewer pipeline?
Small tree roots can also be cut out of the sewer network using a special mechanical auger, which includes a cable with a nozzle at the end for cutting small roots. The cable is fed down the drain and the blades at the end cut the roots. When you are done, you will need to wash the roots out of the line.
With the development of technology, another faster and more efficient mechanical method of removing tree roots from sewers has appeared. Many attachments appeared, such as, for example, a chain nozzle, hydrodynamic saws, “grenades”, “shoes”, etc. Each is designed for a certain type of blockage and effectively copes with its task.
The chain nozzle is most effective for removing roots. The attachment is a cylinder with chains attached to the end. The chains are sized to fit the pipe diameter so that they do not dangle and are taut as they rotate. This allows the blockage to be removed more efficiently.
The chain nozzle is made of hardened steel, which makes it very strong and durable.
The nozzle is installed on the hydrodynamic unit hose. When the high pressure machine supplies water to the hose, the chain nozzle starts spinning at a high speed. The chains at the end of the carousel are ripped out and literally grind the wood into dust
Previously, the storm sewer system was also clogged, we had to periodically call the foremen. But then I was advised to do a hydrodynamic flushing of the entire storm sewer system. We were very pleased with the result.
Now our storm sewers are working much more efficiently.
Unfortunately, it is impossible to do hydrodynamic flushing on your own, for this you need to have equipment.
