A blockage in the sewer pipe is a nuisance that can happen unexpectedly. Draining in an apartment or a cottage can clog at any time. And it’s not always possible to clean it with household chemicals or a plunger.
Agree, calling plumbers expensive and long. It is easier to take a cable to clean the sewer and get rid of the problem yourself manually. This tool is simple to use and will not require specialized skills from a home master.
We will tell you how to choose the right simple device, what rules should be followed when cleaning the sewer. And also give an example of self-manufacturing a simple cable.
What is a plumbing cable and why is it needed?
There are many technical means based on chemistry and methods for cleaning sewer pipes. But the plumbing cable (aka flexible shaft) among them is the simplest, cheapest and most effective option.
With its help in the pipeline it is possible to destroy even old traffic jams from garbage or mud deposits. With this hand tool, risers, drains, toilets and other plumbing are easily cleaned.
A plumbing cable is a tool for cleaning the sewer in the form of a bending spring, which has a handle on one end and a nozzle or just a hook attached
Now everywhere, cast-iron sewer pipes in apartments are being replaced by analogs of plastic. Thanks to the smooth walls inside, plastic drains are less likely to clog than old pipelines made of cast iron. But even in them, blockages still form.
Rags and plastic bags thrown into the toilet bowl turn into tubes in a tube, which can only be destroyed mechanically.

A plumbing cable allows you to break through a solid cork in pipes created by mineral and organic sediment. If there is a cable in the household, you can much less often turn to plumbers
They resort to the use of a sanitary cable if removing a blockage with a plunger or pouring chemicals does not bring the expected results
The cable, as it were, is “drilled” into the plug clogging the pipe and destroys it, after which the destroyed sediments are washed off into the sewer
If the blockage in the sewer pipeline is not timely removed, connections, gaskets may burst and even metal pipes may leak
To clean the sewer pipes, cables of different lengths and cross-sectional areas are released. Imported plumbing is served with thin cables that can pass into the drain holes without removing the grate.
A thick cable with a heavy steel tip will help break the congestion in the sewer riser
For punching a cork from fat and food residues, you do not need a powerful long cable with a large cross section, it is enough relative to a miniature device made in the form of a spring
It should be remembered that the mechanical way of influencing the blockage is not always safe. During cleaning, pipes can be damaged, so before using the cable, it is better to try safer products

How to choose the right option
The principle of using a plumbing cable is extremely simple. First, the tool is pushed into the sewer pipe until it stops, so that it ends up against a blockage.
Then, by means of rotational and reciprocating movements, the handle of the tool picks up the cork with the tip of this end to pull it out or destroy it in place inside the pipeline.
Due to the flexibility of the cable for cleaning the sewage system, they can get a blockage far in the depth of the pipe without disassembling the latter and without removing plumbing for cleaning work
The specifics of the application and the efficiency of use depends on the cable device, the correct choice of tool size.
Consideration of design features of different models
There are four types of plumbing cables in hardware stores:
- cable cars - classic thin rope (rod) of several wires;
- spring - hollow spring, twisted from wire;
- spring-wound - a flexible core with a spiral wound from the outside;
- tape (flat) - tape 1–4 cm wide.
All types of plumbing cable work items (handles, nozzles, tapes, wires) are usually made of durable steel.
There are models in which the spiral is externally covered with a rubberized shell that protects the inner walls of the pipes from mechanical damage by metal. But in most cases, a plumbing cable is just a steel spring without any braid.
On the one hand, the spiral allows the cable to bend around any turns in the sewer, and on the other, due to the torque, it enhances the mechanical effect on the blockage
Cable. A small cable rope 1.5–3 meters long belongs to the household category of tools. It is ideally suited for cleaning sinks, eliminating blockages in the toilet and on horizontal sections of pipelines to a common riser.
Trying to "break" the cork in the depths of the sewer is meaningless. Such a plumbing cable will either not reach the blockage, or it will not simply be able to destroy it.
Spring loaded. The cable is small and ideal for cleaning in-house risers and sewer pipes suitable for them from plumbing fixtures.
Core cable. This is a professional tool that can be used to push the weed plug. It is difficult to do something like this with an ordinary spiral because of its greater softness and compressibility.
Tape. Such a tool is not flexible enough and is not able to go to all corners of the sewer. It, unlike a spring, bends in only one plane. But the ribbon cable has smaller dimensions in a twisted state.
Most often it is used to clean long trunk pipes of large diameter, which have an order of magnitude less bends than in house buildings.
Determination of the optimum working diameter
When buying a cable for cleaning sewer pipes, you must correctly select its cross section. Too thick a tool to clean the sink or urinal is unlikely to succeed. He simply will not enter the drain hole. Such a flexible shaft is designed for cleaning risers and wide pipes of large diameter.
A flexible plumbing shaft is available with a section of 3–32 mm and a length from half a meter to 90 meters, for household needs a tool with a diameter of up to 10 mm and a length of 2-3 m is quite enough
Corresponding diameters of pipes and plumbing:
- pipe D <50 mm - the flexible shaft should be selected with a cross section of up to 10 mm;
- pipelines in 50-110 mm - you need a cable with a diameter of 11-15 mm;
- vertical risers more than 100 mm - you need to choose a tool with a thickness of 16 mm.
An excessively thin 3-4 mm cable can break when the cork is pulled out of the pipe. Such a device is more suitable for cleaning siphons and removing plums from hair.
Punching them a thick pipe with a blockage in the form of a rag is not worth it. A more solid option is required here.
Comparison of a hand tool with an electric
A cable for cleaning sewer pipes has a lot of advantages:
- high torque;
- ideal balance of elasticity and flexibility;
- safety of use;
- simplicity and ease of use;
- high cleaning efficiency;
- the ability to use different purpose nozzles.
With active use for the intended purpose, the spiral of the cable loses its elasticity over time (opens up) and simply breaks. But with proper care, cleaning and oiling after work, this device will last more than one year.
All plumbing cable is good. It is easy to use and cheap. However, this is still a manual tool for which a person needs to make certain efforts. But you can modify it a bit or purchase a professional electrical appliance.
The easiest way to make it easier for yourself to clean the sewer pipes is to supplement the cable with an electric drive in the form of a drill or screwdriver, only you need to turn them on at low speeds
Professional plumbers prefer to use special tools to facilitate work. It can be either a handle on a rigid and stable stand, or a full-fledged power tool with a motor. Plus there are various nozzles for different types of blockages.
A manual version of a conventional plumbing cable is cheaper and smaller in size than an electric counterpart. However, the latter greatly simplifies the cleaning of sewer pipes. If the tool is needed for one-time work, then there is no reason to spend much on it.
However, if you have to clean the sewers constantly on a professional basis in the role of a plumber, then you should seriously think about purchasing a power tool.
Types of nozzles used
Typically, a plumbing cable for sewage has a hook at the working end to pry off a debris plug in the pipe. But a professional tool is instead equipped with a threaded connection for winding a wide variety of nozzles. They can be included with the flexible shaft or sold separately from it.
A brush in the form of a ruff, an expander for wide pipes, a pear-shaped nozzle and much more can be attached to the cable for cleaning pipelines
As a replacement nozzle, the end of a flexible plumbing shaft can be worn:
- «screw"- to remove non-solid deposits from the pipe walls;
- «hook"- for winding and picking up soft knitwear, etc. of things;
- «scraper"- for use in wide pipes and disposal of sediment from fats;
- «harpoon"- for the possibility of impact on the cork with the aim of its engagement and stretching;
- «sliding knife"- for more thorough cleaning of the pipe walls;
- «pick"- for breaking down fatty growths.
There are also spiral, serrated and other knives. Each of them is designed for its own kind of blockage. They can even remove roots and dense calcareous deposits from piping systems.
The plumbing cable is designed to clean not only the domestic sewage system, but also the pipes of the street storm system, chimneys and internal pipes of the septic tank (+)
To enhance the capabilities of a conventional flexible shaft without nozzles and connectors for them, experienced plumbers recommend fluffing the end of the cable.
Rigid wires sticking out in different directions while in the pipe will more reliably catch rags and other debris. This will simplify and speed up cleaning. But to apply such modernization is possible only in metal pipelines. Plastic walls will quickly be damaged by hard hooks.
The nuances of cleaning pipes with a cable
Before cleaning the sewer with a metal cable, the nature of the blockage and the degree of clogging should be assessed. If this is just a rag or a lump of thick cardboard, then a flexible plumbing shaft is an ideal tool for such a cleaning.
However, if a technological blockage has formed in the pipe, which is directly related to the wear of the pipes and their narrowing due to rusting, then only a complete relocation of the sewer system will help.
The handle of the plumbing cable should be turned clockwise only when it is inserted into the sewer. So the spiral, when resting on the garbage plug, begins to gradually compress, increasing pressure and torque.
If the blockage is complex and large, then the process of pushing the cable with the meshing of the cork and pulling out the garbage will have to be done several times.
A pistol-type tool with a cable screwed onto the drum allows you to remove blockages of any complexity, but costs a lot of money - for use in everyday life a simpler flexible shaft in the form of a spiral is enough
If the sewer pipelines are made of plastic, then the cable is best taken with a rubberized braid for cleaning. It will less scrape the plastic walls of the pipes, inevitably damaging them. So the sewer will last much longer.
Before starting work, the spiral should be carefully inspected for possible damage. If during cleaning it breaks inside the pipeline, then it will be problematic to get it. To pull out a scrap later, you will need to disassemble the sewer.
When the cable is jammed in the pipe, it must be carefully and leisurely started to rotate in different directions to release it. You can not pull the tool. And in general, when working, do not make excessive efforts.
After breaking the plug in the pipe with a cable, the sewer should then be washed additionally with boiling water. It does not hurt to pour in a drain and a solution of vinegar with baking soda or another version of a fat-dissolving chemistry. Prevention here will not hurt, but only contribute to the stable operation of the sewage system.
After each use, the flexible shaft must be cleaned of adhering dirt. At the same time, in addition to hot water, it is necessary to use cleaning and fat-breaking agents. For storage, the cable is folded up after wiping with a dry cloth. It is made of galvanized steel, but to leave a drop of water on it is still not worth it.
Subtleties of manufacturing a similar tool
Instead of a factory product, you can also use a homemade plumbing cable to clean the sewer. It is quite possible to make it from improvised materials.
The simplest analogue is a piece of flexible wire with a bent end. However, such a device will be able to clean only a shallow blockage. The thick wire is not so flexible as to push it too far into a curved pipe.
The basis of the plumbing flexible shaft can be made from a conventional steel cable, taking a fragment of the latter for this and attaching a handle to it
The procedure for manufacturing a hand tool for mechanical cleaning of sewers:
- Cut a piece of 1-3 meters long from a metal cable.
- Fluff one end to form a brush.
- Twist the other end into a ring and attach a handle to it for convenience.
- Treat steel with an anti-corrosion compound.
A plumbing cable made in this way can be used for cleaning toilets, bathtubs and sewer pipes.
It is not as versatile as a professional device for cleaning, but it is quite suitable for independent use in everyday life.
Several interesting videos will help you in choosing a tool and tell you how to make a cable with your own hands.

A detailed briefing will help to make a homemade cable:
The mechanical method of cleaning the sewage system is used only as a last resort, when household chemicals and plungers are no longer able to help.
Working with a plumbing cable is not the most pleasant pastime. Specific sewage mud is poorly washed and extremely aggressive. But with a serious blockage, this flexible shaft cannot be dispensed with. And you don’t even have to call the plumbers, you can clean the clogged pipe yourself.
