Water and electricity renovation is a crucial step in the renovation, and it is essential that the foundations be laid. No matter how beautiful the late renovations may be, the water and electricity retrofits have failed to do everything in their entirety. So there's a rumor in the water and electricity retrofit that it's “unstoppable, unstoppable”. How can we choose between the top, the top and the wall for water and electricity? Then we'll tell each other what's better for waterways and circuits
Part 1: is the retrofitting of water tops, floors or walls
The retrofitting of waterways is generally top or ground, and very few are walled because of the irregularity of the horizontal openings。
The top of the waterway is not to open a sink on the roof, but to follow the corner of the wall and the top, with the advantage of facilitating maintenance and replacement at a later stage, with problems of maintenance not permeating the floor, with the disadvantage that the top of the roof is a waste of water pipes, and usually a sling to hide the pipes to ensure beauty, with a consequent increase in costs。
Waterways go to the ground: the overall cost is much cheaper and the safety of water pipes on the ground is high. However, in the event of water pipeline problems, the floor is to be ripped open and later maintenance is more problematic. The choice of the field must ensure that the water pipes are too hard。
In summary, the recommendations for the retrofitting of the waterways, especially the bathrooms and kitchens, do not damage the waterproof zone and do not affect the neighbours in case of infiltration。
Part 2: will the circuit be on top, floor or wall
For the top of the circuit, for the minor make-up, it is possible, in terms of value and utility, to support the path, the purchase of water and electricity materials, and the construction of hard items, usually with 50 or 70-year agreements, until the water and electricity route is completed, and it is important to take photographs and keep them for later periods in order to find them. It's best to be self-suited, and it's a waste of money and material that the authors feel they're leaving。
It is important, however, to ensure that the material needed to be wired, to seek out the full name of the company, to sign a post-sale agreement and to ensure that the guerrillas who seek to save money are not found on the road。
Part 3: hydroelectric retrofit sixs
1. All-house circuit designs with designers。
2. The master enters the field to use the design drawings for the opening of the wall and the floor。
Installation of pipes, pre-burial pipes and dark boxes。
4. Electric and waterway test voltage, with pressure of 6 to 8 voltage, maintained at 30 for leakage。
5. Sew and block the opening with concrete sand or sequestering。
6. Inspections and comprehensive inspections of adapted circuits to ensure safety。
Part 4: elements for the construction of utilities
1. All cold and hot water to the water pipe shall be calibrated with a 200 mm single-snailed zinc-coated straight tubing, including horizontality, verticality and spacing. Cement slurry can be fixed only after correction. (recommended for plywood fixation)
2. When it is cold, hot and parallel, it cannot be less than 100 mm apart, and the hot pipe should be above the cold pipe, and when a mixed tap is installed, the hot water should face the left. The distance between the centre of the cold and hot water convection bathing in mixed taps is 150-160 mm。
3. Cold and hot water pipes are not allowed to mix, and the cold and hot water pipes leave the end of the water bend and dent 2-5 mm from the wall to completion。
4. Cold and hot water pipes are embedded in walls, not less than 10 mm from the wall, and not less than 15 mm from the wall; (note: preventing hot water temperatures from visualizing cement and ceramics) cold and hot water pipes are not less than 100 mm in parallel; cold and hot water pipes must be separated by insulated materials at the intersection。
5. Aqueous pipe is a ppr or pvc pipe。
6 the in-house plumbing supervisor is required to have six points and the bronchial four points。
7. The construction of circulatory water is carried out according to the following pattern: hot water pipes are collusive (i. E. Non-division). The chain goes to each hot water exit and the last hot water exit is accompanied by a circulatory tube to the water heater point of contact, where it is installed to recycle the pump。
8. Laundry machines shall be reasonably equipped with faucets and water, and drainage shall ensure that discharges are smooth and do not return。
9. When the gas pipeline and direct drinking water need to be retrofitted, the owner must be warned in advance to contact the relevant department and submit a plan to the owner。
10. Water valves to and from which water heaters are installed must be located in accordance with the requirements of the product instructions and with the owner's approval of the location of the installation, and the company's reservation of gas pipelines。
11. Cold and hot water valves in the kitchen wash basin are installed at an altitude of 450 mm。
12, cold and hot water horn valves in the basin are at an altitude of 500-550 mm, and the wash-basket pipe should be placed in a wall and treated with deodorant。
13. The mixed tap of the ordinary tub shall be placed in the middle of the tub (first determining the size of the tub), at a height of 150 - 200 mm above the surface of the tub, and the tap shall be discharged 100 mm from the side of the tub。
14. Cold and hot water pipes shall be laid along the wall, hot and cold, at a height of 300-400 mm。
All sewers and drainage pipes must be checked for access, with appropriate protective measures. All cleaning materials are thoroughly checked before installation。
Summarizing the above article, the editor-in-chief suggested that the waterways should go to the top and the electricity should go to the ground. Of course, there is a great deal of debate on the internet as to whether to go to the top or to the floor or to the wall, and it is important that you learn to distinguish yourself in the renovation。
