Modern technologies are developed at such a high level that even a person without special education and knowledge can easily build his own house. The main thing is to observe the most important rules when performing these works. For example, choose suitable diameters for steel pipes. Then everything will be in order with the water supply.
Water supply installation. Features
PVC pipes and galvanized steel pipes are the most common designs that are most often used for installation of pipelines in homes. If installation is to be carried out outside the building, bituminized steel pipes are most suitable. The diameters of steel pipes in this case can be completely different. Glue is usually used to connect PVC pipes , steel pipes are connected using a fitting.
First, the water main is broken. In addition, holes in the walls and ceiling are marked, fasteners are installed. The number of turns and bends along the entire pipeline should be minimal. But it is permissible to make a slight horizontal slope, this allows, if necessary, to drain water from the system. The diameters of steel pipes can be changed to some extent so that the system meets all the requirements.
After this, fasteners are installed, holes in building structures are pre-punched. Then the pipes can be prepared for laying, preparatory work is completed.
Next steps
First of all, it is necessary to measure the distance to the branch or the middle of the first turn of the pipe from the existing connection to the device. Only after performing this action can you prepare a section of pipeline with a suitable length. The diameters of the steel pipes must also match the rest of the elements.
In order to screw a piece of pipe into a particular section, use a pipe wrench, it is placed on the pipe, trying to get as close to the connection as possible. The pipe is secured with a bracket after the connection is completed. If there are any excess elements, then they are removed using the most ordinary hacksaw. So all sections are laid, sequentially.
When the work is completed, the pipeline should be tested under high pressure. It should be 1.3 times higher than the normal working. Pipes must withstand it for ten minutes. Only after the tests are carried out, the holes in the walls and ceiling are sealed with a special solution. This rule applies to any pipe equally, even a steel pipe "diameter of 20 centimeters" is no exception.
How is sewage installed?
If an open gasket is used, then polyvinyl chloride and polyethylene pipes are most suitable. But when it is necessary to organize a system underground, it is better to use ceramic products. If we talk about risers, then they are mounted from the bottom up.
The installed part of the water supply must face upwards with the coupling . Laying pipelines in the basement is the first step from which installation of sewage systems always begins. Plots need to be firmly connected to each other, then lift up.
After that, the coupling is sealed, part of the pipelines are fixed by means of brackets or clamps. It is necessary to fix all laid lines, a steel pipe "diameter 50 centimeters ”also requires additional verification. In addition, you can now first install the pipeline and then install the finished unit. This method is especially relevant when it comes to the horizontal location of the pipeline itself. Open ends are closed with corks of wood so that they do not clog.
