Replacing water and sewer pipes is usually necessary when the system is partially or completely worn out. And if a decision is made to carry out engineering works without the participation of professionals, it is necessary to prepare in advance and know how to independently dismantle the sewer.
Do-it-yourself repair work is dangerous in that even when replacing a worn part, there is a possibility that the leak will reappear. As a result, if the sewer pipes are not credible, it is better to completely change the entire system. But before that, it is necessary to dismantle the sewage system.
By replacing pipes, it is possible to completely change the system of their arrangement, especially since today materials allow this to be done without any special problems. Modern materials, for example, metal-plastic pipes are more reliable, strong and durable than cast-iron pipes, and most importantly, sewer pipes are installed rather quickly and relatively easily.
When replacing the entire riser, it will be more expedient to change all plumbing and bends on the equipment. In addition, when you can change the entire route of the old collector run. In this case, it is necessary to strictly observe the correct slope and diameter of the pipes.
Tools and materials
When buying the required materials, you must mainly pay attention to their quality, not price (as many do). Unnecessary savings and the use of cheap, low-quality materials often turn out to be sideways in the future. It is necessary to make sure in advance that all purchased equipment is not subject to corrosion and is resistant to mechanical damage.
To remove worn-out sewer pipes, you will need:
- a pencil for marking;
- Bulgarian;
- hammer;
- chisel;
- sealant;
- cement mortar.
Materials that may come in handy:
- rubber cuffs for fastening pipes in sockets;
- pipes of the required diameter and required length;
- tees;
- expansion joints for joining sewer pipes;
- special plastic adapters;
- clamps for mounting pipes to the wall surface.
Sewer system
Using a grinder, the pipe, which is adjacent to the tee, is cut off at a distance of at least 10 cm from the socket of the riser.
Dismantling cast iron sewer pipes begins with dismantling the riser. When performing these works with your own hands, you should know that previously, cement-based solutions were used to perform sealing. Such formulations only get stronger over time. As a result, dismantling an old sewer system can be a lot of hassle.
Replacing the riser may be the most difficult. Indeed, in the good old days, masters performed the filling with sulfur. To liquefy such solutions, it is necessary gas-burner or blowtorch... When burning, sulfuric solutions emit harmful vapors into the atmosphere, so the use of a respirator by workers in such cases is simply a necessity.
When dismantling the riser in your apartment, it is forbidden to make strong blows and loosen parts.
This can lead to damage to the elements located in the apartments adjoining above and below.
From this it follows that it is better to change pipes to all neighbors in the riser at once.
Specialists carry out dismantling of sewer pipes in the following order:
- cast iron pipes are cut with a grinder;
- first, 2 cuts are made horizontally, and the distance between them should be about 10 cm;
- using a chisel, break out and remove pieces;
- the tee is dismantled;
- the rest of the pipe is being disassembled.
Other ways to dismantle
After the socket is dismantled, it must be thoroughly cleaned and the old grease removed.
There are several ways to dismantle the sewer system.
If the pipeline is not securely assembled, then you can loosen it at the connections. After that, the system is disassembled into separate parts. It is also possible to split cast iron pipes into small parts with a hammer. To do this, you first need to work with a grinder. This method is good in that it is possible to save the place of joining the sewer fittings with plastic pipes... But in any case, it will be necessary to cut off the sewage system from the docking unit. Finally, the pipe is cut off using a special steel wedge. It is hammered into a cutout, which is made by a grinder.
Very often, on old sewer risers, ready-made assemblies were used, which were assembled from individual parts in factories. All joints of such parts were sealed with sulfur, and dismantling of such a sewer system, as mentioned above, cannot be carried out without the use of open fire.
In any case (that is, it does not depend on the chosen method), all norms must be observed fire safety and other standard requirements.
Nuances and features
In order for the sewage system not to turn into an endless nightmare, you must adhere to simple rules:
- start laying pipes from the bottom;
- the location of all sockets should be towards the water flow;
- it is better to change the entire riser at once, and not its individual components;
- the riser is connected to the toilet using pipes with a diameter of 11-16 cm, the washbasin is joined by pipes with a diameter of 5-7 cm;
- before starting work, it is necessary to make a markup of the future system. If it is assumed that the pipes will hide, then it is necessary to groove not the depth of concealment, but taking into account the necessary slope;
- when assembling the system, it is better to lubricate all gaskets and joints with vegetable oil;
- when choosing sewer pipes, it is necessary to ensure that there are no cracks and all kinds of swelling on their surface. They can further cause leaks.
As you can see from the above, the sewerage system is easy to disassemble. And almost every man can cope with this task without any problems.
The level of comfort in a private house depends on the well-organized work of the whole complex technical systems: plumbing, heating, ventilation, sewerage, electrical. As soon as one of them fails, living in the building becomes problematic. Failure of communications that drain household wastewater is considered emergency and requires immediate repair. Let's try to figure out when a local replacement is necessary and how to properly dismantle the sewer pipes.
- current;
- capital;
- emergency.
Reasons guided when doing maintenance, lie in ensuring the smooth functioning of the network, that is, in the timely replacement of worn-out fragments (usually small in length or volume). These can be linear products, fittings, tees, water locks, etc. Sometimes it is required to change the direction of the line or add an additional branch when connecting another plumbing fixture.
Overhaul includes full replacement sewer equipment: riser, wiring, internal and external outlets. More ambitious changes are possible, for example, the installation of a new septic tank or the laying of a prefabricated structure from a separate building (for example, guest house) to a common highway. Major changes can affect the inner and outer segments separately or be carried out simultaneously.
The most common reason for the dismantling of sewer pipes is the deterioration of the system. Old-style parts inside the house - usually cast-iron vertical and horizontal highways - are replaced with plastic and metal-plastic counterparts. For outdoor furnishings, both popular PVC elements and products from traditional materials are used: ceramics, asbestos cement, steel. Possible and combined options... For example, with a partial replacement of the in-house network, a cast iron riser is left, and the pipework, including all fittings, is changed to plastic
Replacing cast iron with a polymer analog
If you do not take care of preventive work in time and delay with current problems, you can wait for the most unpleasant type of repair - emergency. Minor emergencies are resolved fairly quickly. For example, a blockage in the kitchen can be removed with a wire rope, cleaning fluid, or a plunger. A major accident destroys the entire system and is capable of upsetting the ecological balance in the adjacent area. So the depressurization of external equipment leads to contamination of the soil with household waste and groundwater which contradicts sanitary standards... It is necessary to establish the cause of the leak, isolate the emergency section or completely change the entire network.
Dismantling the external line
Changes in the design of external communications are made quite rarely, since the most suitable pipes are selected even during the design process. The cross-section of the products is calculated based on the actual amount of wastewater, and I arrange the structure so that household waste flows by gravity into the septic tank. If the calculations are performed correctly, and the installation is done according to all the rules, the system will function for a long period - from 10 to 50 years. In case of incorrect calculations, installation errors or the choice of a low-quality building material there is only one way to correct the situation - by completely replacing the outlet line, having previously dismantled the unsuccessful option.
Replacing pipes outdoor sewerage
Disassembly is carried out in the following order:
- using the diagrams of the initial installation, determine exactly where the underground external highway passes;
- perform excavation- remove the top layer of soil from the outlet in the area of the foundation of the house to the septic tank (if necessary, in the area between the two chambers treatment plant);
- when cleaning is done from all sides, depressurization is carried out: the insulation is removed, waterproofing material, remove the connecting elements (fittings, clamps, couplings);
- get out the old parts.
As a rule, worn-out pipes are not used in the future, therefore, a cutting tool is used to disassemble problem areas (for example, elements glued by a bell-shaped method) - an electric saw, a grinder, a perforator. In some areas (especially in the area of joints), it is enough to cut and then smash with a sledgehammer - this applies to cast iron and ceramic products. Plastic is also cut into more convenient for transportation, but larger pieces, since its weight is much less.
Renovation of the line leading to the septic tank
Simultaneously with the dismantling of the highway, the trench is being prepared for the installation of new communications. The assembly is carried out taking into account the errors of the original device, which may include the following:
- insufficient sealing of joints;
- absence correct angle tilt;
- selection of products with incorrect parameters (narrow section);
- violation of the installation technology (for example, the absence of revision wells at turning points or intersection points).
If you do not know how to properly dismantle sewer pipes, contact the specialists - for a small amount you will save both time and own strength... And most importantly, you will be able to avoid repeated repairs.
Dismantling the sewer network inside the house
Restoration of communications inside the house seems easier only at first glance. You do not have to get the soil, as when dismantling an external sewage system, but there is a number of equally laborious works. Let's figure out what nuances require special attention.
Dismantling of cast iron pipes and riser
If your sewage system is 30-50 years old, then most likely cast-iron parts were used during its construction (with the exception of the supply lines to plumbing equipment). Disassembling metal wiring is a laborious process that requires certain skills, since you will have to wield a metal-cutting tool and use special techniques for removing cast-iron fragments.
Sewerage layout in multi-storey building
It is easier to change equipment in a private house or in the country, since no approval is required either with the neighbors or with the house management. If you are the owner of a city apartment, before starting work, you will have to notify all neighbors in whose apartments a common highway passes. You also need to negotiate with representatives of the HOA or a housing company, and it is better to conclude a repair and maintenance contract with them - then you, in addition to a professional replacement, will receive warranty obligations.
When all organizational issues have been resolved, you can begin to dismantle the vertical and horizontal pipes of the intra-apartment system (or the sewage system of a private house).
Stages of work:
- Shut off the water supply (to the apartment - if we are only updating the wiring, on the whole riser - if we are replacing it).
- Disconnect the connecting devices of plumbing and electrical equipment (toilet, bidet, washing machine, shells).
- Disconnect all plumbing fixtures and clean the technical area.
- Dismantle horizontally located elements - it is better to do it in fragments, cutting into parts with an electric cutting tool or grinder.
- Remove the central vertical.
The thick, vertical piece - the cast iron riser - must be carefully removed in small pieces. Here is one of the popular techniques: they make alternately deep cuts at half-meter intervals, and then knock down the remaining jumper with a sledgehammer or a hammer and chisel. Do not forget that cast iron is heavy, so we try to divide it into small parts. Be aware that splinters of cast iron falling into lower part(on the first floors) can create an emergency blockage, and then the sewer equipment on all floors will have to be changed.
Hardened deposits on the walls of the cast iron riser
Socket joints and welds are the most difficult to disassemble. Usually they are not broken, but cut out and taken out entirely. If you want to replace only the wiring, and keep the cast-iron riser, first try to swing the horizontal element, and then get it out with a chisel, chisel and hammer. We take out the disassembled metal parts for removal to a landfill and prepare a room for the installation of new parts.
Video example: dismantling a fan sewer tee
Replacing the plastic system
V sewer structures from PVC and polypropylene installed in newly built houses, replacement options have been thought out, therefore, most often it is not necessary to dismantle the entire network, it is enough to remove one fragment. Plastic parts differ in strength and durability, however, they also deteriorate over time. There may be several reasons: a chip, a crack, a factory defect that was not noticed during installation, or incorrect welding. separate parts... Sometimes the depressurization of the communications leading to the riser from the kitchen or bathroom occurs due to mechanical damage caused by the installation of new furniture and plumbing equipment.
Plastic elements are much easier to remove than cast iron counterparts, since they weigh less and are easier to cut. You should start with the connections to the external equipment: it is necessary to turn off all devices and clean the repair area. Then manually or with cutting tool disassemble the pipeline one by one along the entire length. Sometimes, in order to save money, the emergency section is removed, replacing it with a new part - the functionality of the system as a whole will not change from this. Unlike cast iron counterparts, plastic products have a perfectly smooth surface inside therefore do not build up hard deposits and can be reused.
When disassembling, pay attention to rubber seals at the joints - it is possible that the leak was not due to pipe wear, but due to sealing errors.
Possible errors and ways of preventing
When dismantling old equipment and re-arranging sewer lines, try not to repeat the mistakes that may cause the next repair.
Possible pipe layout
Here are some important points:
- when changing a riser in a multi-storey building, try to agree on replacing it in all apartments - this will simplify further maintenance;
- follow the location of the socket - it should be directed towards the movement of drains;
- if you change the system on two or more floors of a private house, start repairs from the bottom, from the first floor (or basement);
- take into account the dimensions of the products: for external sewerage - at least 110 mm, for a riser - at least 100 mm, for outlets of the internal network - 50 mm;
- for the device of joints and connections of elements of different diameters, use adapters and tees;
- take a little time for preliminary layout and calculations - this way you will save time and money.
An analysis of practical shortcomings in the following video:
Dismantle sewerage system easier than installing a new one, nevertheless, here, too, special knowledge is required and work experience is desirable. If you want to quickly get rid of old pipes and install new communications, contact an engineering and construction company, which will quickly and efficiently carry out all dismantling work, and also organize the removal of used parts.
Outdoor networks are designed to supply living quarters different kinds communications: supply of gas, heat, water, etc. In addition, they carry out the drainage of sewage.
Internal networks meet human needs by creating comfortable conditions residence. Often, when dismantling systems, a number of related works are performed, such as removing asphalt, disassembling the foundation base, demolishing wells, land works and etc.
Quickly. Just. Conveniently.

Dismantling of electrical wiring.
Failed electrical wiring is a great danger to human life. Therefore, it simply needs to be replaced. Before proceeding with this kind work, you must remember the safety rules.
The old electrical network is de-energized, so there is no need to remove the old wires from the wall. But sockets, boxes and old switches are usually removed. This is done with a puncher. It makes no sense to leave old sockets in the walls, not only because they spoil appearance premises, but also because for all new electrical appliances it is the new sockets that fit. When dismantling the interior walls, it is also necessary to get rid of the electrics.
Dismantling of the sewer system.
Old sewer pipes can cause you a lot of trouble, including a foul smell. It should be noted that the smell is not so bad, since it occurs as a result of the multiplication of microbes that can harm human health. Pipes made of cast iron, as a result of long-term operation, often leak. It is advisable to replace them with plastic ones.
Use a chisel and hammer drill to remove the pipe from the concrete. When working with these tools, you should be careful and be extremely careful not to damage the socket, which will remain in concrete floor.
You can connect used pipes using cement mortar or minting.
Dismantling the heating system. In this process, there is something in common with the dismantling of the sewerage system.
Pipes should be knocked out of the wall, as well as from the ceiling. This should be done with a puncher, being careful. Heating pipes smaller in diameter than sewer pipes, so no difficulties will arise.
With help circular saw it is necessary to cut off individual pieces of pipes. Install plastic pipes instead of old pipes, since they are not subject to corrosion and will serve you for more than one year.
Dismantling the water supply.
The procedure for dismantling the water supply system is similar to dismantling heating system... It is worth paying attention here that the whole process should take place when the water is turned off, so as not to flood the neighbors and not to find unnecessary problems.
Dismantling ventilation.
If you need to install new ventilation equipment or adjust air circulation, you must dismantle the old ventilation. In high-rise buildings, with large quantity apartments, the ventilation duct is common for all residents of the building, therefore, interfere with this system undesirable.
If ventilation is poor, there is an expansion option ventilation duct... For this we need a puncher. Clean the channel or mount it there special fan, which will forcibly circulate air. There is one drawback here - if the fan breaks down, the ventilation will stop working. But at the same time, forced ventilation greatly improves traction.
All the works mentioned above require a decent level of qualification from the performer, therefore, it would be more expedient to entrust this matter to specialists who will help save not only your precious time, but also your budget!
