Most high-rise buildings and private houses built several decades ago have cast iron sewer pipes. Many systems still work fine, but sooner or later they have to be changed. In addition to normal wear and tear, the question of appearance is also relevant. Cast iron is too massive, ugly and requires constant maintenance. Replacing cast-iron sewer pipes with plastic at the same time solves both problems.
Cast iron products are extremely durable, so it rarely happens that pipes installed even 40-50 years ago collapse. However, they often become clogged and require cleaning. The work of the sewerage system is disrupted due to a thick layer of deposits on the inner walls of the pipeline, and the owners of the premises decide on a major overhaul of the network. As an alternative to cast iron, plastic is most often chosen.
Why plastic is considered the best option
There are several options for replacing a cast iron sewer pipe, including the same good old cast iron. Modern cast iron products are more technological, easy to install and almost as durable as those that were produced half a century ago. But in most cases, home and apartment owners choose plastic. There are several reasons:
- Smooth inner walls. This is the most valuable property for sewer pipesof wire transfers. No deposits form on smooth surfaces, the permeability of the pipes is high, and their diameter hardly decreases over time. Replacing cast-iron sewer pipes with plastic solves the problem of frequent blockages. If the pipeline is clogged, it is easier to clean it.
- The lightness of the material. Plastic is ten times lighter than cast iron, so any products made from it are easier to transport, carry, climb stairs, and mount. Often he is chosen precisely for these reasons.
- Ease of assembly and disassembly. To install a plastic pipeline, you do not have to buy complex expensive equipment. It is much easier to mount than cast iron. If necessary, the structure is also easily disassembled. If you need to replace the damaged section, there will be no problems, everything can be done by hand.
- Tightness. Homeowners who have had to install cast iron pipes on their own are well aware of how difficult it is to achieve tight connections. There are no such difficulties with plastic products. Manufacturers produce not only the pipes themselves, but also additional elementsfacilitating installation.

A few words about the shortcomings of the material
Whatever the merits of the plastic, it is not perfect. To make an informed decision, it is worthwhile to understand its shortcomings well. The main one is poor resistance to high temperatures.
In many ways, the operating temperature range depends on the quality of the material and manufacturing technology. Polymers with good performance are not cheap, so when choosing, you should focus not only on prices, but also on technical indicators.
Plastic sewerage may not withstand prolonged exposure to hot liquid. So, at a temperature of 60 degrees, the pipeline is sometimes deformed. A temperature of 90 degrees can seriously disrupt the operation of the system; repairs will be required.
Manufacturers of plastic sewer pipes are well aware of the problems faced by consumers, therefore they offer products with special coatingsreducing risks. They cost a little more than traditional ones, but they tolerate better high temperatures, soundproofed, have a high throughput.
What is needed to replace cast iron sewer pipes
The best option for residents of apartment buildings is to negotiate with neighbors and change the sewage system throughout the riser. This will help ensure efficient operation of the entire system. In addition, all residents will calmly accept the temporary restrictions on the use of the sewage system.
Before starting work, calculations should be made. If the new system exactly repeats the scheme of the existing one, there will be no problems. If you plan to install new plumbing fixtures or change the pipe laying scheme, then it is imperative to make calculations and double-check them several times.
After making sure that the drawing and calculations are correct, you can buy the right amount of materials, components, shaped elements, as well as prepare tools. You will need a hammer, chisel, measuring instruments, and a marker. Additionally, you should buy sanitary silicone sealant, cement, liquid soap.
It is highly desirable to provide for an inspection hatch, even if it was not there before. This gives the home owner free access to inspect and repair the system. The choice is huge. You can purchase a decorative structure or find an invisible hatch and finish it with the same materials as the walls.
Important: materials and tools
To simplify the dismantling of the cast-iron sewage system, it is necessary to prepare a large hammer or sledgehammer, a grinder. Sometimes a gas burner is required to disassemble the system. A decent alternative is a blowtorch. The number and type of tools depends on how the old pipeline was assembled.
Old sewerage systems were collected using cement-based compounds. Over time, they only become harder, which makes dismantling very difficult. Sulfur filling was used when installing the riser. It is strong and durable, and can only be destroyed with a blowtorch or gas torch. In order not to be poisoned by toxic vapors, you have to use gas masks.
Dismantling of sewer pipes and riser
If it was not possible to agree with the neighbors and you have to change the sewer pipes in only one apartment, they need to be disassembled very carefully, trying not to damage the elements of the system in other apartments. Too active actions during dismantling can lead to the destruction of part of the common riser, and then you will have to pay for its repair.
Features of disassembling the sewage system
First of all, the sections of the sewer pipes coming from the bathtub, toilet and washbasin are disconnected. It is important not to break the plumbing. If you can do it without problems with the sink and the bathroom, then sometimes you have to say goodbye to the toilet. Older models were often installed on a strong cement mortar, so dismantling is difficult. Most often, the bowl of the toilet can be saved, but part of the leg can break off.
If you initially plan to replace the toilet, you can not take care of it and just break it with a sledgehammer. Then it remains only to get the device in parts. The main thing is to remember that sharp fragments are scattered in all directions, and to take care of the safety of people in advance. After dismantling the toilet, the remaining parts of the system are disassembled, completely removing the putty and, if necessary, cutting the pipes.

Things to remember when dismantling a riser
One of the most crucial stages of replacing cast-iron sewer pipes with plastic ones is dismantling the riser. Here are a few useful recommendations from specialists:
- To cut metal, you will need a grinder or pipe cutter. The pipes are cut horizontally by making two cuts. The distance between them should not exceed 10 cm. Do not cut through the metal, otherwise you can damage the tool disc. It can get jammed between parts of the pipe if it sags under its own weight.
- When the cuts are ready, a chisel is inserted into them and pieces of pipes are broken off with a hammer or small sledgehammer. It is important to choose a tool made of wood or with a special rubber nozzle and do not hit with force, so that metal fragments do not fall into the pipeline. Cast iron is fragile and shock-resistant, so a little effort is enough and it will burst itself.
- To make it convenient to work and not damage the riser to the neighbors, it is cut off about 1 m from the tee and 8 cm from the ceiling. To do this, use either a grinder or a hand hacksaw. In the second case, you will have to come to terms with the long dismantling process, because Sawing cast iron takes a lot of time and effort.
- Dismantling the sewer system requires caution and adherence to safety measures. In addition to work gloves and overalls, it is highly desirable to use personal protective equipment - glasses and respirators, because metal dust can enter the eyes or respiratory system.

Installation of plastic pipes - the main nuances
How to replace cast iron sewer pipes with plastic ones? There are several important points:
- The system is assembled from bottom to top, installing sockets against the flow.
- For additional protection of the joints, a silicone sealant is used. A possible option is a linen roll.
- Rubber cuffs are installed at the joints of old and new pipes. To make them easier to mount, use liquid soap.
Sequence of installation work
A plumbing collar is connected to the cut pipe, and a tee is connected to it. The joint is carefully sealed. The expansion pipe is inserted into the pipe as far as it will go. Make sure that the distance to the edge is at least 5 mm. After that, you can assemble the system without sealing the joints.
If the fitting went well and there were no unforeseen difficulties, then proceed to the final assembly of the system. Start by installing wall mountings. Then the pipes are assembled according to the scheme and sealed.
When the work is completed, the operation of the system is checked by pouring a large amount of water into the sewer. It is necessary to check whether the joints are wet. If everything is normal, the system is ready to be put into operation.
Replacing cast-iron sewer pipes with plastic ones requires skills. If the system is assembled incorrectly, blockages may occur, problems with the discharge of wastewater. Therefore, it is worth doing the work on your own only when the owner is 100% confident in his abilities. If there is no such confidence, it is better to hire a team of plumbers.
Most of the houses in Moscow, which were built during the Soviet Union, still have a sewer system, assembled from cast iron pipes. Today, plastic is much more practical. Products from it are easily assembled without the use of additional devices. Replacing sewer pipes in an apartment is a fairly popular service offered by many companies at various prices and prices. At the same time, the entire range of work is completed in just a few days. This concerns the dismantling of the old cast-iron sewage system and the laying of a new plastic system. This material does not corrode and when correct installation can be operated for more than a dozen years. In this case, you can also replace the water supply in the apartment.

Pipes made of plastic are used to create pipelines different types due to many advantages - corrosion resistance, low weight, easy installation. Therefore, replacing a cast-iron sewage system with a plastic one is an excellent solution, but dismantling old pipes is not so easy. This job requires experience with power tools. When replacing, you must follow the safety rules. You can see how plastic products look like in the photo. The advantages of plastic pipes:
- low price compared to other types of similar products;
- durability (serve for several decades);
- do not rust;
- light weight, which facilitates the installation process and allows you to do it yourself.
Preparing to replace the cast-iron sewer with a plastic one
Dismantling a cast-iron sewer with your own hands begins with the preparation of tools.The work is done using:
- chisels;
- a hammer with a nozzle (rubber or wooden);
- puncher;
- chisels;
- 2 adjustable wrenches, knives, screwdrivers, scrap, steel wedge for parsing pipe parts;
- grinder, grinding disc and 3-4 pieces of 125 mm discs.
Before dismantling, it is determined how the cast-iron parts (in particular crosses and tees) were connected to the shaped section, for which it is required to find the connection point - usually it is located higher than the level flooring... If tiles are laid on the floor or there is a screed, then a puncher or chisel is required to search. You need to work with them carefully - you cannot damage the bell that remains in the overlap.
The connection between tees, crosses and pipes can be done in three ways:
- filled with gray;
- polymer-cement mixture;
- caulking with a solution. You can use cement-sand or cement.
Dismantling the old cast iron sewage system
As for how to dismantle a cast-iron sewer, this work takes place in stages:- The vertical pipe is cut with a pipe cutter. If not, then this work can be done with a grinder by making two cuts with an interval of 10-15 centimeters from one another. They need to be placed at a slight angle relative to each other, and converge near the wall, where the pipe is not cut, so that its top does not sink. The product is cut 3/4 in relation to the perimeter. Using a wedge driven in on both sides, the cut out area is broken off with a chisel, and the remainder is knocked out with a hammer. Pieces are removed carefully so that they do not fall into the drain and thus clog the system.
- Subsequently, the upper edge is cut off at a specific height. In order to easily connect the cast-iron sewer with the plastic one in the future, a section of the pipe coming from the ceiling is left at the top. Its height must correspond to the parameters of the molded product, pressed during the installation of plastic products. The cut is performed relative to a horizontal line, therefore, the place of the cut is pre-marked with masking tape. Applying a sharp blow directed towards the wall, the pipe is destroyed in the place where the cut was made. Cast iron products are fragile, and problems with this cannot arise.
- Usually, the lower part of the riser has several components. They can be revisions, couplings and other elements. To check the strength of the connection, you need to carefully, trying not to damage the lower socket, swing the rest of the pipe. If possible, they begin to pull it out in parts, helping with a crowbar.
Dismantling can be difficult if the seam is practically absent, and the solution glued the elements together too tightly. In this case, an old metal sheet is used to expand the joint. If in the end it was not possible to disassemble the connection, then the fittings should be cut off 2-3 centimeters above the joint.
The piece of pipe that remains in the socket is cut with a grinder, while the protection is removed, at different angles of inclination of the disc. Fragments of fittings remaining inside the pipes are removed using a special wedge.
There is nothing difficult in how to disassemble an old cast iron sewer. You just need to be patient.
Preparing for the installation of plastic pipes with your own hands
Replacement materials will be required:- trumpet plastic diameter 50 millimeters;
- mountings for the riser;
- rubber cuff (sewer transition from cast iron to plastic);
- shaped elements made of plastic (crosspiece, tee, compensating branch pipe, sometimes revision).
The pipes are cut to the calculated length, the end should be chamfered or sanded with sandpaper. In order to accurately determine the length of the product, an expansion pipe is placed into it until it stops. Then the resulting structure is also inserted to the limit into the remainder of the cast-iron pipe located in the upper ceiling. Minimum size the gap that should remain between the tee or cross and the resulting assembly cannot be less than half a centimeter. Pre-assembly is performed without using rubber pads and cuffs.
Regarding how to dock a cast-iron sewer with a plastic one, it makes no sense to use pipes instead of sliding couplings for this purpose.
Several fixings are placed in the wall. If ceilings have standard height, then three pieces are enough, if they are high - then 4.
To complete the final assembly, mount all the required cuffs and gaskets, apply soap to the ends of the products, connect the pipes. After the final installation of the riser and the completion of the clamping of the fastening clamps, the operability of the sewage system is checked by passing a large volume of water through it. The replacement can be considered finally completed only after the successful completion of the tests.
There is nothing difficult in how to change a cast-iron sewer to a plastic one. You just need to follow the instructions exactly. If you have doubts that it will be possible to do this work correctly, you should contact a specialist. Plastic sewer provided correct execution work, will last for decades without requiring repair. For this reason, if the cast iron pipes are leaking, it is better to immediately change them to plastic ones.
Replacing a sewer riser in an apartment is a very messy and difficult process.
Usually the replacement of sewer risers in apartment building is performed centrally and simultaneously, immediately along the entire riser.
In this case, the work is carried out faster, there is no need to preserve one or another element during de installation worksoh.
The cost of replacing risers in an apartment is also lower, per tenant, and the team's earnings are higher. therefore construction companies and the teams are happy to take on such contracts. It's hard, dirty, but well-paid work.
Replacing the sewer riser is usually formalized through the house management, it is more convenient than arranging for the work to be carried out privately. In this case, there are legal guarantees of the quality of work.
It would seem that cast iron is a metal and, by definition, should inspire more confidence than plastic. This is not always the case for sewerage systems. Cast iron has a porous and bumpy structure, and therefore, pollution builds up rather quickly inside the cast iron sewer pipes.
Cast iron sewer riser - joint with plastic pipe
Its inner diameter decreases, permeability decreases, and the likelihood of blockages increases many times.
Cast iron pipes that have served for more than 20 years can be completely overgrown from the inside by plaque.
During dismantling, there were cases when, under the blows of a sledgehammer, cast-iron risers broke into pieces, and the petrified pillar from the plaque remained in place.
Plastic sewer pipes are smooth and, with proper installation, significantly surpass cast iron ones in terms of throughput parameters. The positive effect of replacing with plastic will be obvious immediately.
Sewer plastic riser
The reason for replacement may also be the presence of cracks, fistulas, faults in the existing sewer system or its general deterioration. The replacement of the cast-iron pipes of the riser in the apartment must be made after 25 years of operation.
It makes sense to change the sewer risers at the same time throughout the riser. Replacing a sewer riser in one apartment will cause a number of inconveniences to neighbors, but absolutely will not increase the efficiency of wastewater flow.
Rather, there will be an additional cause of blockage at the joints connecting cast iron and plastic.
Preparation for work and tools
For dismantling, you will need sledgehammers, hammers, grinders, a hammer drill. It may take several discs for a grinder, the work is quite exhausting.
In some cases, a gas torch or blowtorch may be required.
Chisels, special hammer - chisel, screwdrivers, metal wedge, silicone sealants. You will also need ladders or goats.
It is highly undesirable to carry out work on dismantling cast-iron sewer pipes alone.
Materials for work
- Rubber cuffs - seals to ensure the tightness of joints with a cast iron pipe, if any;
- 11 cm plastic tee or cross;
- Sewer plastic pipe 110 mm. Be sure to make sure by marking that this is exactly the sewer option. This moment important because sewage has a high level of aggressiveness. In addition, the pipe must be resistant to acidic or alkaline-based cleaning agents;
- Compensators for pipe diameters;
- Plastic adapters with cuffs;
- Pipe clamps and fasteners;
- Plastic bends for possible alignment of the riser.
Plastic pipe for internal sewerage 110 mm
Don't forget about personal protection. Thick construction gloves and mittens, safety glasses are required. You will also need a respirator with a fresh filter or a gas mask. Working clothes with tight and soft knee protection will help you prevent the development of joint diseases.
The water supply must be shut off throughout the entire riser. Notices must be placed in the entrance in advance in order to warn the tenants.
It is also advisable to go around all the apartments and inform additionally about the time of work.
Dismantling the old riser
Dismantling work should be done with extreme caution, since cast iron is a very brittle material.
If suddenly the riser is not replaced in all apartments, the likelihood of damage, chips, pipe breaks from neighbors who do not want to change the cast-iron sewer riser to a plastic one is very high.
Leaving pieces of old cast iron pipe inside the floors is wrong and dangerous.
Even if visible cracks and chips can be avoided, micro-cracks and cavities in cast iron residues are almost certain to appear. And you will be responsible for the fragrant sewerage leaks.
To resolve the issue with neighbors who do not want to pay an additional fee for changing risers, you can negotiate with the management company. Payments for major and current repairs must be paid to the rent invoices.
When making a contract through a management company, payment will be made from the funds that have already been paid by the tenants.
Cast iron pipes for sewage have their drawbacks, so it is recommended to choose a cheaper, but at the same time reliable option - plastic. - pros and cons, installation features.

Removal scheme
Having stepped back about 10 cm from above, an incision is made in the old pipe.
At a height of about one meter, a second circular incision is made using a grinder.
Dismantling scheme of a sewer riser
The incision should not be completely round, but go a little in a spiral. This is necessary to avoid pinching the grinder disc and corresponding, often serious, injuries.
A chisel is inserted into the incision and several strong blows are made with a hammer.
After you have tapped the cuts with a chisel in a circle at the top and bottom, the cast iron pipe should burst. In accordance with the instructions, the pipe should burst exactly along the cut. But since it is a cast iron pipe, porous and old, it can burst as you please.
Sewerage scheme in the apartment
therefore experienced craftsmen cut the pipe into small pieces and break off in parts, approaching the joints with extreme caution.
The old riser must be removed. It is advisable to immediately remove the fragments of old sewer pipes from living quarters.
Embossing cast-iron pipe
A cast iron riser can be fixed in a socket in two main ways:
- Stamping the riser with carbolic acid and impregnated rope.
- Caulking with sulfuric filling.
Sealing pipe joints with gray
To find out, you need to try to loosen the pipe by tapping on it with a rubber sledgehammer. If the pipe moved almost immediately, then carbolic acid was used. Continue to gently rock the pipe and pull out the impregnated rope with pliers.
If sulfur has been used, strong impacts can damage the riser. Using a blowtorch or gas torch, the pipe is heated at the junction in a circle.
Sulfur fumes are poisonous. It is imperative to wear gas masks and provide ventilation.
Warm up the pipe, softening the sulfur mass that has sealed it, and continue rocking. It is convenient to hold the pipe with pliers or an adjustable plumbing wrench.
After the pipe has been removed, clean the socket seat of sulfur or carbolic residues. When using a chisel or chisel, be careful not to break the socket.
All this many hours of vigil with pipe loosening can be avoided by simultaneously replacing the riser. Old pipes are broken, taken out and taken out. Together with sulfur, carbolic acid and sockets. In their place, new ones are installed. The space between the floors is filled with polyurethane foam. Even the soundproofing is improved.
Pipes made of polyvinyl chloride are increasingly used for laying outdoor sewerage systems, since they do not form plaque and rust, and they have a low cost. Read carefully -: features of installation and laying in the ground.
How to solder correctly different kinds read plastic pipes.
Installing a new
- A rubber cuff is put on the upper piece of the cast-iron pipe. The connection is carefully coated with sealant.
- A plastic adapter is installed on top of the cuff.
- At the bottom, a second rubber adapter is inserted into the socket.
- The compensator is installed in a tee, each connection is carefully coated with a sealant.
- The pipe is firmly fixed to the wall with clamps to avoid displacement.
It is important to accurately calculate your strengths and capabilities when carrying out such work of increased complexity. Replacing a sewer riser is a job for an experienced team of plumbers.
In the event of an error and a drain, the cost of the error can be very high.
