Waterway reconstruction of decorative literacy

The first step of decoration should be waterway reconstruction. Some houses have water and electricity lines when they are handed over, but not all the decoration can meet the needs of the owners, not to mention the water pipe material of the waterway taken by the developers is not ideal. The material of water pipes is very important in this concealed project. If there is no problem in the use process, you must choose a better water pipe material. Only in this way can we install a safe home. Today, let's take a look at the relevant knowledge of waterway regulation.

Significance of waterway reconstruction:

Hydropower transformation is the first step of the whole decoration construction. No matter how to save money, quality should be the first premise. It refers to the renovation process of replacing all or part of the waterway used by the original developer 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:

According to the design drawings, the construction personnel shall determine the anchor point with the owner → protect the finished product on the construction site → stretch the line along the line direction → fix the water card on the top surface along the stretch line direction → open the slot along the stretch line direction → clean up the muck → press the water pipe on site → check whether there are any errors in each loop → conduct suppression acceptance test on the waterway (which belongs to the acceptance project, see the relevant knowledge of hydropower acceptance in the next section) → close the water tank.

Problems needing attention in waterway reconstruction

1. The renovation of the secondary waterway for home improvement follows the principle of "following the course", which is convenient for later maintenance, does not affect the height of the floor and does not greatly increase the ground height.

2. The commonly used reference size data for waterway renovation in home decoration (the size is based on the data of damaged and untreated wall surface): the center distance of cold and hot water pipes of shower mixer 150MM, the distance from the ground 1000- 1200 mm: the nozzle height of the upper flip washing machine1200mm; The height of the water inlet of the electric water heater is equal to the clear height of the floor-the distance from the top of the fixed electric water heater-the diameter of the electric water heater-200mm; The height of the water inlet of the basin is 450-550 mm; The water inlet of the toilet is 200MM away from the ground, and generally 250MM away from the center of the toilet. The water inlet 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 orientation of the design drawings. In the actual operation process, it is necessary to contact the relevant product manufacturers through the owner, and master the positions and sizes of different types of cabinets, water purifiers, washing machines, basins, bath mixers, water heaters and other models, so as to prevent the related equipment from being unable to be installed due to operational errors in the later period.

4. Generally speaking, the right side is cold and the left side is hot (unless individual equipment has special requirements).

5. Pipe cutting: use a special pipe cutting machine to cut the pipe, and the bayonet of the pipe cutting machine should be adjusted to be consistent with the cut pipe diameter. When rotary cutting, the force should be even, and the broken pipe should be vertical and flat without burr.

6.PPR pipe welding: PPR pipe adopts hot melt connection mode, which is the most reliable, with high interface strength and higher safety performance. Before connection, dust and foreign matter on pipes and accessories should be removed. After the connection is completed, you must hold the pipes and fittings tightly and keep enough cooling time before letting go.

7. When the hot-melt pipe is made of different materials, such as 7. PPR, PB and PE must be connected with each other by special adapters or mechanical connections, and direct welding is not allowed.

8. The top surface of the water supply pipe should be fixed by metal elevator, and the distance between straight-line fixing clips is generally ≤ 600 mm ..

9. Pay attention to the special treatment of the joint between the original metal pipe and PVC pipe in the reconstruction of the second-hand house drainage pipe to prevent the leakage of the sewer pipe due to improper treatment.

10. If indoor conditions permit, the main control valve of water supply pipeline should be installed as far as possible to facilitate future maintenance; If there is any water meter modification, it is necessary to reserve maintenance space and maintain the water level of the modified water meter.

1 1. Detailed drawings shall be issued for the record after waterway reconstruction.

The problem of Mr. Liu in Impression Spring City Community

What should the owner do for this step:

1, waterway design should first consider all water-related equipment, such as water purifier, water heater, kitchen treasure, toilet, washbasin, etc. Their locations, installation methods and whether hot water is needed; It is necessary to make good use of gas or electric water heaters in advance to avoid temporary replacement of water heaters, which will lead to repeated reconstruction of waterways; In addition to the washbasin, toilet, washing machine and other outlets, it is best to bring one out to facilitate the later water mop;

2. It is the first time for a cabinet manufacturer to come to the door. It is best to bring the construction master who changed the water together and communicate face to face. Before construction, the upstairs should be waterproof to ensure that there is no water seepage downstairs before construction.

3. After waterway reconstruction, suppression experiments should be done. The fireman reminded me to press 6 to 8 atmospheres with a press to keep it from leaking for 30 minutes. It is best to have a property on the scene to suppress the test, which can play a supervisory role; Because some decoration teams will cheat the owners in this link.

4. After the kitchen and bathroom floor tiles are laid, check whether the floor drain is unobstructed (the drainage speed after removing the floor drain cover shall prevail, because most deep-water sealed floor drains have the problem of slow drainage); If you want to close the redundant floor drain, you must block the gap between the drain pipe and the floor drain to prevent water from overflowing;

5. It is best not to use deep-water sealed floor drain for washing machine floor drain, because deep-water sealed floor drain has a common feature of slow launching, which is used for deep-water sealed floor drain in shower room and other positions. Floor drain can basically meet the drainage demand because of the small amount of water; However, the drainage speed of washing machine is very fast, which can not reach the drainage speed of deep-water floor drain at all, which directly leads to water overflow.

Summary: After reading so much knowledge about waterway reconstruction, everyone has a certain understanding of waterway reconstruction. If you want to carry out waterway reconstruction, you must pay attention to the matters needing attention in waterway reconstruction, whether it is toilet or kitchen waterway, you must be foolproof.
