To flow into the sewage pipe is a very unpleasant situation that can happen with any system. The appearance of holes occurs from normal wear and tear of pipes or improper use. The same seal the crack in a cast iron sewer pipe, if the problem is caught off guard, there is no time and money on service calls.
Simple ways to eliminate leaks improvised means
Most often there are problems with cast iron pipes, which are made from water in the apartment during the Soviet era. The best way to eliminate the problem of a large system wear - complete replacement of the pipeline and sewage in the toilet. When the money for this is not enough, you can use a variety of ways to temporarily eliminate the cracks.
Before starting any repair work should be carried out preparatory steps:
- Shut off the water in the water pipe and the riser.
- Inspect the scene of a breakthrough education. To do this, carefully review the place pipes connection. These places are the most vulnerable of cast-iron pipes. The cause of the leakage in the joints can become negligent plumbing when installing the entire drainage system or in consequence of impulse actions (water hammer).
After installing the spill area is followed by corrective action. The problem of what and how to seal the cast iron sewer pipe, is solved in various ways, thus can be used as assistants, and advanced materials for repairing cracks. Here it is necessary to clarify that the repair of the old cast iron system is possible if the problem is minor and the hole is small. Or the problem is in the joints.
The flow on the surface of the pipes can be eliminated by the following methods using available tools.
1) Install the clamp in place leaks, using rubber gaskets. This method to close a crack requires access to the pipeline at a distance of not less than 50 mm. This condition in small spaces is not performed, especially at corner placement bathrooms. Before installing the clamp surface should be cleaned with metal brushes dirt and old paint.
2) Overlay gauze impregnated with cement mortar or a waterproof adhesive, in places of longitudinal cracks. This method is effective only for the low-pressure pipe. Work is carried out as follows:
- The surface is cleaned thoroughly before formation of pure metal.
- Next, prepare the cement slurry in the ratio 1: 1.
- Fold gauze of several layers, pre-measurement of the size of the crack in accordance with the parameters. Take it with a margin of 2-3 cm.
- Immerse into the prepared solution and wait until it is not well saturated.
- Further, the resulting material is applied on the cement leaking place and secured with a rubber plait or wire.

3) Another common way - to set a stub. To do this you need a wooden wedge small size, so it does not become a cause of clogging the sewage system. Place the cover in place of the holes and secure it by wrapping conventional gauze bandage. Material before it should be soaked in the epoxy resin solution.
4) If a crack is large, it is possible to cover a special tool prepared from phosphoric acid and copper oxide. To do this you must do the following:
- Place leaking cleaned of rust and old paint residues.
- Crack deepens and degreased coating around it.
- Prepare a solution of 3 parts copper and 2 parts acid.
- Seal the crack will get to make the necessary preparations as soon as the mixture hardens quickly.
Note! Associated with crack large, this method can only temporarily fix the problem. Completely avoid the problems will only complete replacement of the entire sewer system.
5) Epoxy resin. It is made on the basis of the adhesive. The advantages of this material include long service life, which is 50 years. But she does not tolerate exposure to chemicals. Therefore, to eliminate blockages, if necessary, can not be used dissolving chemicals.
Technical sulfur. To use it, you need a burner which heats the material. Then pour over the crack. To work with him to be careful with the use of special means of protection.
Embedding using a sealant
To eliminate fistula and small cracks in the cast iron pipes can take advantage of new materials. These include sealants. When using this tool, you must take into account the recommendations given on the label, the hydraulic pressure in the system and to comply with the technical regulations.
The sealant is selected considering the diameter and length of the sewer system pipes and gutters. To address issues related to leakage in the joints should be treated seriously. Classify several types of insulation material:
- Self-adhesive tape. With their help conduct sealing adhesions between the tubes, insulation sleeves, nodes waste guttering structure. Anticorrosion tape produced from bitumen-rubber mixture is applied from above the protective film. The advantages of this material include high strength and chemical stability of the composition of any reagents. She is able to securely hold the leak, allowing the tube to remain in operation for a long time.
- Sealant based on silicone. There are two types: neutral and acid medium. Solving the problem areas with neutral agents will be more expensive than the sealing gaps by acid sealant. The material is produced on the basis of silicone, which has excellent adhesion properties.
Self-adhesive tape - modern insulation means that you can easily use in emergency situations involving leaking pipes. To use it correctly and to carry out quality repairs, you need to take the following steps:
- Prepare a metal surface near the leak, preliminarily cleaning it from dirt and rust.
- Tear tip of the whole tape coil and attach it to the side of the crack be sealed.
- Then an insulating tape is wound movements is placed on the problem area. At work, make sure that the material was tightly stretched and overlapped in a spiral.
- Ultimately, the cracks should be place under a double sealant layer.
Silicone sealant - a panacea for sealing holes not only iron, but also plastic. For work with this material, you need to perform a few simple steps:
- Before you start, check the surface of the pipe and make sure that it is clean and dry.
- Hold the tip of the tube with the gel and carefully spread it across the fracture surface, including areas associated with it.
- Apply 2-3 coats should be no smearing on the sides of the joint, but only slightly stepping beyond the boundaries of the problem area.
Experts advise extrude sealant using specially pistol device. If it's not, you can use an ordinary hammer.
Eventually
When, do not despair you have problems in the cast-iron sewage system. There are many tools to help you troubleshoot a break and avoid a lot of trouble. Observing all the rules of work with the material, you will be able to conduct high-quality sealing of leaks by hand.
