Hydropower renovation is the first step of the whole decoration construction. No matter how you save money, you should first take quality as the premise. It refers to the decoration process of replacing all or part of the waterways and circuits used by the original developers according to the decoration configuration, family population, living habits and aesthetic concepts. Hydropower transformation is divided into waterway transformation and circuit transformation. What are the precautions for hydropower transformation, and what work should the owner prepare during this period

the first step of decoration should be the renovation of waterways. Some houses have water and electricity routes when they are handed over, but not all the renovation can meet the needs of the owners, not to mention the material of the water pipes of the waterways open to business is not very ideal. The material of the water pipes of such concealed works is very important. If you want to have no problems in the process of use, you must choose a better water pipe material, Only in this way can we install a secure home. Today, let's take a look at the relevant knowledge of waterway reconstruction

meaning of waterway reconstruction:

hydropower reconstruction is the first step of the whole decoration construction. No matter how you save money, you should first take quality as the premise. It refers to the decoration process of replacing all or part of the waterways used by the original developers according to the decoration configuration, family population, living habits and aesthetic concepts. Generally, it is called hydropower transformation together with circuit transformation

waterway reconstruction process:

the construction personnel determine the positioning point &rarr with the owner according to the design drawings; Protection of finished products on the construction site → Snap the line according to the line trend → Fix the water clamp &rarr on the top surface according to the snapping line; Slot according to the direction of snapping line → Clean up muck → According to the size of the site → Fixing of water pipe on the top of wall → Check whether there is error in each circuit → Carry out pressure acceptance test on the waterway (belonging to the acceptance project, see the next chapter on hydropower acceptance for details) → Closed water tank

precautions for waterway reconstruction

1 The transformation of the secondary waterway of home decoration follows “ Water walks the sky ” In principle, it is easy to maintain in the later stage, and there is no need to significantly increase the ground height without affecting the floor height

2. Commonly used reference size data for domestic decoration waterway reconstruction (the size is subject to the rough untreated wall and ground data): the center distance between the cold and hot water pipes of the shower mixer is 150mm, and the distance from the ground is 1000-1200mm; The water inlet height of the upper flip washing machine is 1200mm; The height of the water supply outlet of the electric water heater is equal to the clear height of the floor - the distance from the fixed upper part of the electric water heater to the top - the diameter of the electric water heater -200mm; The height of water supply inlet of water basin and vegetable basin is 450-550mm; The water supply outlet of the toilet is 200mm from the ground and 250mm from the center of the toilet; The water supply outlet of the mop pool should be 200mm higher than the pool itself Other water supply and drainage dimensions are determined according to the product model

3. The waterway reconstruction shall be carried out in strict accordance with the direction and positioning of the design drawings. In the process of practical operation, it is necessary to contact the relevant product manufacturers through the owner to master the location and size of the water supply and drainage outlet required by different models of cupboards, water purifiers, washing machines, basins, bath mixers, water heaters and other models, so as to prevent the failure to install relevant equipment in the later stage due to operational errors

4. Generally speaking, it is facing the direction of the water supply outlet, cold on the right and hot on the left (except for the special requirements of individual equipment)

5. Pipe cutting: the pipe is cut with a special pipe shear. The bayonet of the pipe scissors should be adjusted to match the diameter of the pipe being cut. When rotating and cutting, the force should be even. The broken pipe should be vertical and flat without burrs

6. PPR pipe welding: PPR pipe adopts hot-melt connection, which is the most reliable, with high interface strength and higher safety performance. Before connecting, remove the dust and foreign matters on the pipes and accessories. After the connection is completed, the pipes and fittings must be held tightly and kept cool for enough time before they can be released
