In most of the buildings constructed during the Soviet era, the sewerage system is made of cast-iron pipes. This is due to the fact that such products are not only a long service life, but also do not lend themselves to a variety of influences. However, pipes made of iron require proper installation and appropriate use.
Compared with other types of communications, aqueducts dwellings often need to be replaced (every few years). In addition, installation of plumbing fixtures and repair of the house, may require changes to the system design. To perform a caulking iron pipes in the apartment with his hands, not necessarily undergo special training. It is possible to make, having only the skills to work with standard tools. How to carry out the dismantling of the old pipe and install a new one, you will learn in this article.
The algorithm of work
Depressurization of the cast-iron elements is one of the most difficult tasks in self sewer repair. To do the work quickly and efficiently, it is recommended to prepare in advance all the necessary tools.
To carry out the work needed:
- bolgarka (with the help of the tube can be cut);
- wheels for grinding;
- goggles, gloves and mask;
- soldering (useful for heating compounds);
- hammer;
- Screwdriver different sizes and configurations;
- pipe wrench;
- chisel.
Note! To prevent the spread of odors around the room and getting into the pipeline of various waste, close the drain plug with a cloth.
The sequence of this work:
- The first step, before the cast-iron sewer raschekanit trubuyavlyaetsya tapping joint place with a hammer. It should do so with caution. Otherwise, you may damage the structure, leading to a complete replacement of the riser. It is also possible to carry out such manipulations are often used tools made of wood.
- Once done tapping, you should pay attention to the condition of fasteners. If the pipe goes from side to side, and it is possible to detach it, you must do the following. You need to shake the product, hooking it with a screwdriver. Rope should catch the pliers and gently pull.
Tip! During the procedure should be more swing pipe.
- If even after frequent and prolonged sound of hammers, the tube has not changed its position, it can be concluded that the attachment was carried out using a sulfur solution. should first burn the dried mixture to remove fasteners. This can be achieved in several stages. The first step is the heating of the junction with a soldering iron. This should be done in a circle. Next, we need to continue hammering, trying not to disturb the integrity of the product. If the design of the elements stagger the start, you can also try to dismantle the item using the key.
- Successfully dismantled units should carry out a thorough cleaning of joints with a chisel. Emphasis needs to be done to clean the edges, because in this place will be installed rubber sealant.
- Before setting, the material for the seal, lubricate special substance.
- The final step is the installation of a new product in the prepared area.
By the combustion of sulfur necessary to compulsorily wear a protective mask and goggles. They will not let harmful fumes to seep into the body.
Prevent the emergence of problems
It must be remembered that the technical characteristics of the cast iron are not perfect. Products made of this material is quite fragile. Poor quality cast iron is subject to deformation when exposed to fluid, and the processes that take place therein. Changing temperature conditions may also adversely affect the resistance of such pipes, which reduces their ability to transfer the strong pressures.
The process of minting iron drain pipes, as can be seen from the article is quite simple. As for the installation, there would be need a little work.
Mounted element is necessary to qualitatively strengthen the junction by applying a resin layer. Tighter fixation can be achieved with the help of special tools. they are sold in DIY stores.
Tip! Before zachekanit iron drain pipes, the first thing to do - is to calculate the space for installation of the new pipe and, if necessary appliances.
If your plumbing system needs a part replaced, then put off this process is not necessary. This is due to the fact that even the smallest crack is capable of a relatively short time increase when would entail large costs.
Compound sewer pipes
During installation of sewer pipes in the pipeline, empty spaces may appear in the joints. Often it affects the proper operation of the system. For high-quality connection with the removal of all the gaps and voids, special materials must be used. The most popular option is the use of cement and asbestos.
Application solutions of cement
First must install a sealing material. To do this, use a rope, which is pre-impregnated with resin. Then the prepared sealant is required to wrap around the edge of the pipe from the outside. This will prevent the rope to enter the pipe depth.
Important! Using special tools on third increase speed.
To prepare the solution needed follows. The ratio of water and cement must be 9: 1. In cold weather, use well-heated liquid. Allowing the mixture to cool, it should be applied at the fixing portions. Compacted inside seams can be dissolved with a hammer. In order to ensure better fastening to the surface of cement and other materials, should be covered with a wet cloth ready portion.
A compound of cement and asbestos
the use of a solution-based method of asbestos is similar to the previous method. It's suitable for the installation of pipes made of cast iron and other materials.
The algorithm is:
- Mix in a bowl with the dry asbestos cement in ratio 1: 2;
- Next, add a small amount of water and let the mixture stand for a while. Then mix composition until uniform.
To say what the best way to fix pipes, it is impossible. When used properly, any of the fixing methods, you can achieve good results.
In order to qualitatively carry out works on dismantling and strengthening elements, you should know all the details and rules of procedure. Only then can you be sure that your system will last for many years and will not have an effect. The process consists of many complex operations. Therefore, in order to fix the connection quality cast-iron sewer pipes with your hands, you must adhere to the advice and recommendations.
