Sewer repair using KANKOSEI technology

Repairing sewer pipes is an urgent task because if a sewer pipe is defective, the runoff poisons the soil and can contaminate groundwater, which is sometimes sucked into the drinking water transportation system.

To carry out repairs of sewerage systems, a pneumatic punch is used with a pipe destroyer and a pipe expander, which, under the action of a winch, move along the axis of the existing pipeline, destroying it, while at the same time a new pipeline is pulled into the resulting well. The pipeline is built up directly in the well with short pipes on a threaded connection. Thus, sewer pipe repairs are carried out quickly, efficiently and unnoticed by others. They also carry out this “pipe-to-pipe” repair, where existing cast iron, ceramic or asbestos-cement pipes that need repair are tightened, and new polyethylene pipes are pulled up.

Among the main reasons for sewer repair, experts identify:

• periodic clogging of individual sections of the pipeline, which can occur in the event of line subsidence due to laying on soft soils, incorrect installation, and also if the well tray is faulty (it can be broken or have significant roughness);
• leaks at the junctions of network elements or in pipelines are eliminated by replacing worn elements, eliminating cracks by welding;
• freezing of drains due to insufficient insulation of the line;

release of gases from the network (this situation may arise if the exhaust pipe ceases to perform its functions).

How to repair it yourself

You can take some measures yourself, but this does not always end in success: with an unprofessional eye it is rarely possible to correctly determine the cause of a breakdown. It’s better to contact our company right away, so you will save time and nerves.

Before the specialists arrive, you can partially correct the situation by:

1. Clear clogs with a plunger or chemicals;
2. It is worth checking the siphon and removing waste accumulations from there by unscrewing the valve and cleaning them with a cable. After this, it is better to replace the seal, tighten the pipe tightly and make sure that it does not leak. You can clean the toilet in a similar way.
3. If the problem is leaks, find the leaking area and place a bucket or other container under it. You can seal the damage yourself using special means: sealant, cold welding or aluminum tape.

Even if you manage to fix the problem, you may encounter it again - so at least consult with specialists, or better yet, order sewer pipe repair.

How does professional work work?

Depending on the nature of the problem, methods for solving it are selected.

Hydrodynamic cleaning

Theoretically, the sewer system should be built so that it can clean itself. But blockages still occur for various reasons:

• due to irregularities in pipe slopes;
• ingress of large insoluble objects that are not amenable to water flows;
• failures in hydraulic mode;
• long service life without preventive cleaning.

To get rid of build-up and contaminants, a water flow is connected to the pipeline under high pressure (up to two hundred atmospheres). The diameter of the cleaning hose must correspond to the cross-section of the pipe. It is inserted into the pipe 50-70 centimeters deep and, turning on the pressure, is moved forward through the holes located in the nozzle. An internal household network requires no more than 20 liters of water for this, and an external one - up to 30; for an industrial system, much more will be needed.

Elimination of cracks

Most often, leaks occur at pipe connections. While the sewerage system is being repaired, its use will have to be suspended. First, the joints are dried with a rag and cleared of cement, then plumbing linen windings are laid. After this, prepare a polymer cement solution (with water and glue) and coat the leakage areas; instead, a regular sealant will do; it will dry in 5 hours.

After completing the repair work, wait a day for the sealed area to dry, and only then begin to use the sewer system for its intended purpose.

Pipe replacement

Sometimes they are used for so long that they wear out and become damaged. In this case, you need to dismantle:

1. Turn off the water and disconnect the hose connecting the toilet flush barrel using an adjustable wrench.
2. Unscrew the toilet from the floor and, if possible, remove all plumbing fixtures.
3. Disassemble the old sewer; you can break a cast iron pipe with a hammer; this can be done quickly due to the fragility of the material. Remove those that are attached to the tee on the riser very carefully; it is better to cut them off using a grinder, stepping back 10 centimeters from the socket. Then, gently rocking, try to remove the residue; if this does not work, make small cuts in a circle at intervals of 2 cm.

Repair of plastic pipes

If a small crack has formed in them, it can be eliminated by ordinary soldering. If the holes are large, this cannot be done; other measures must be taken:

1. You will need equipment for propylene welding, it is available in any hardware store. Turn it on and let it warm up, during which time you can dry the area of ​​the breakdown.
2. Take the bread pulp and stuff it into the space that needs repair, and start soldering with a hot machine with a special nozzle, this will take 10-15 seconds. If you have to deal with a large breakdown, then purchase propylene rods.

External sewerage repair

Faults can occur not only inside, but also outside the network, then trenchless repair technology is used. To do this, either remove the old pipe and replace it with a new one, or lay an additional one in it, but of a smaller size. This is a very difficult process, it is better not to undertake it yourself. If you are dealing with a well, it is difficult to organize the process so as not to damage its walls, otherwise they will have to be concreted or the masonry completely restored.

Repair of internal sewerage

Before it is carried out, it is not necessary to vacate the residents; the main thing is to organize the work in such a way as not to interfere with their livelihoods. Before you start repairing, make sure that:

• there are partitions between floors;
• the walls where the pipes are laid are plastered and contain slots to allow them to pass through;
• the house is insulated (during winter repairs of sewer pipes);
• wiring has been installed to ensure connection of power devices;
• there are the necessary materials and instruments to check sanitary conditions.

Many people try to fix problems on their own, wanting to save money, but this often results in the emergence of new problems. In any case, you will have to spend not only money on materials and equipment, but also time and nerves. It is better to immediately order a professional repair service. Workers will diagnose the system and select the appropriate technology.

What is internal sewerage?

Internal sewerage is a system for disposing of wastewater resulting from household work or sanitary and hygienic measures. The components of these communications are:

• pipelines;
• ventilation devices;
• wastewater receivers;
• pumping equipment.

The drainage system can be connected to centralized communications for the disposal of household waste, or it can be autonomous. Based on this, the specifics of repairing internal sewerage are determined.

Storm drain maintenance

Maintenance of storm sewer networks involves cleaning the receiving tanks from sand, debris and other foreign objects. In addition, work is being carried out to replace worn out trays, underground pipes, and other elements. Technical work is carried out on the pressure sections of the system - repair of pumps, replacement of filters. An inspection is carried out to check the condition of metal parts prone to corrosion.

The specific operation of stormwater systems is seasonal. This means that the internal cavity of the pipes is empty for some time. Rodents and birds can live there, and garbage can accumulate there. Checking the condition of channels or rainwater collectors allows you to detect unwanted elements in time and immediately remove them from the system. This work is carried out in the fall, after the end of the rainy season. The second check is carried out in the spring, before active snow melting begins.

Eliminating leaks in cast iron pipes

Scheme of the sewer riser.

What are the reasons for the need for urgent repair of a sewer riser?

The inspection shows that it is necessary to carry out work without dismantling the equipment in the following cases:

• if leaks have formed at the junction of pipes;
• if there are cracks in the riser body.

The first step in the job is to determine the cause of the leak in the cast iron pipe. If a defect has formed at the entrance to the riser, it may be necessary to create a seal. It should be taken into account that the defect at the pipe junction must be eliminated in a short time. To carry out work without dismantling the equipment, you should purchase tools and materials:

• chisel;
• hammer;
• seal;
• cement;
• container for mixing the solution;
• water;
• lead cones;
• liquid glass;
• medical bandage;
• paint.

When eliminating leaks at pipe junctions, it is necessary to perform the following operations:

• remove old cement;
• remove the remaining stuffing from the cracks;
• prepare a fresh layer of sealant;
• eliminate the defect using cement mortar.

Tools for sewer repair.

To create a high-quality connection, a mixture of asbestos, cement and water is prepared.

When removing smudges, the joints are cleaned, and then lead cones are hammered into the gap. Unfortunately, the home craftsman may not have a sealant.

This means that he must use ordinary cement to eliminate defects. At this stage of work, the old coating should be removed from the surface of the pipe.

Prepare a working solution. The bandage is moistened and laid in a dense layer at the joint. After 2 hours, fix the coating by applying a layer of paint on top.
