Is it better to go on the roof, on the ground, or on the wall for water and electricity renovation? After reading this, you don’t have to worry anymore!

Water and electricity renovation is so important for decoration, and a good foundation must be laid. No matter how beautiful and high-end your later decoration is, if you don’t do everything right in the water and electricity renovation, it will be in vain. There is a saying in the hydropower transformation: "Go to the top, not to the ground, go vertically, not horizontally." Regarding the direction of hydropower, whether it is to go to the top, go along the ground, or go along the wall.

Water and electricity renovation is a crucial step in decoration, and a good foundation must be laid. No matter how beautiful and high-quality the later decoration is, if the water and electricity renovation is not done well, everything will be in vain. So there is a popular saying in the hydropower transformation: "Go to the top, not the ground, go vertically, not horizontally." Regarding the direction of hydropower, how should we choose between the three options of roof-mounted, roof-mounted and wall-mounted? Next, let’s talk about which one is better for waterway or circuit renovation?

Part1: Should the waterway reconstruction be carried out on the roof, on the ground or on the wall?

Waterway reconstruction is usually carried out on the roof or on the ground, and rarely on the wall, because the horizontal grooves along the wall are very irregular.

Roofing by water: Roofing does not mean making grooves in the roof, but walking along the angle between the wall and the roof. The advantage is that it is convenient for later maintenance and replacement, and it is easy to repair if there is a problem. The disadvantage of penetrating downstairs is that it wastes water pipes when going to the top. Generally, a suspended ceiling is needed to hide the water pipes to ensure the aesthetics. The cost increases a lot.

Waterway on the ground: Compared with the roof construction, which saves materials, the overall cost is much cheaper, and burying water pipes on the ground is also safer. However, if there is a problem with the water pipe, the floor will need to be pried open, which will be troublesome to repair later. When choosing to go underground, you must ensure that the quality of the water pipes is excellent.

I conclude: It is recommended to move the waterway to the roof, especially the bathroom and kitchen, as this will not damage the waterproof layer and will not affect the neighbors if water seepage occurs.

Part2: Should the circuit transformation be carried out on the top, on the ground or on the wall?

Years of agreement, remember to take photos and save them when the water and electricity route is completed so that problems can be found later. The one that suits you is the best choice. I think going to the top is a complete waste of labor and materials.

However, when walking, you must pay attention to the quality of the wire material. Try to find a regular big brand decoration company, and be sure to sign a good after-sales agreement to guarantee it. Never go to the guerrillas on the roadside just to save money.

Part 3: Six steps of water and electricity renovation

1. The whole house electrical and waterway design is completed by a designer.

2. The master comes in and grooves the walls and floors according to the design drawings.

3. Install pipelines, embed pipelines and cassettes.

4. Test the electrical circuit and water circuit pressure. Press the pressure at 6 to 8 and keep it at 30 to see if there is any leakage.

5. Fill the gaps and block the openings with cement mortar or caulking agent.

6. Inspection: Conduct a comprehensive inspection of the modified circuits and waterways to ensure that nothing goes wrong.

Part 4: Main points of hydropower renovation construction

1. The outlet elbows of all hot and cold water supply pipes must be corrected with 200mm long single-threaded galvanized straight pipes, including horizontal Degree, verticality, spacing. Only after correction can it be fixed with cement mortar. (It is recommended to use the splint fixation method)

2. When the cold and hot are arranged in parallel, the distance should not be less than 100mm. The hot water pipe should be above the cold water pipe. When installing the mixing faucet, the hot water should face the to the left. The center distance between the hot and cold water elbows of the shower mixer faucet is 150-160mm.

3. Hot and cold water pipes are not allowed to be mixed. The end face of the outlet elbow of the hot and cold water pipes is recessed 2-5mm from the finished surface of the wall.

4. The hot and cold water pipes are laid embedded in the wall. The distance between the cold water pipe and the wall is not less than 10mm, and the distance between the hot water pipe and the wall is not less than 15mm; (Note: To prevent the temperature of hot water from affecting the cement and porcelain tiles to create images) the parallel distance between cold and hot water pipes shall not be less than 100mm; the intersection of hot and cold water pipes must be separated by insulating materials.

5. Air conditioning sewer pipes are PPR pipes or PVC water supply pipes.

6. Indoor water supply pipes require 6 points for the main pipe and 4 points for the branch pipe.

7. Construction principles for circulating water: hot water pipes are of the serial type (that is, not branched). Go to each hot water outlet in series, add a circulation pipe to the last hot water outlet to the water heater contact port, and connect it to the circulation pump during installation.

8. The faucets and sewers of the washing machine should be reasonably arranged, and the drainage of the sewer pipes should ensure smooth drainage and no water return.

9. When gas pipelines and direct drinking water need to be relocated and renovated, the owner must be reminded in advance to contact the relevant departments and submit a plan to the owner.

10. The installation of the water heater's inlet and outlet valve positions must be based on the requirements of the product manual, the installation position approved by the owner, and the gas pipeline installation position reserved with the gas company.

11. The installation height of the hot and cold water angle valve for the kitchen sink is 450mm above the ground.

12. The height of the hot and cold water angle valve of the basin is 500-550mm from the ground. The water pipe of the wash basin should be buried in the wall and treated with deodorization.

13. The mixing faucet of an ordinary bathtub should be installed in the middle of the bathtub (first determine the size of the bathtub), with a height of 150 to 200mm above the bathtub surface, and the water outlet of the faucet should be in the bathtub away from the edge of the bathtub. Water comes out at 100㎜.

14. Hot and cold water pipes must be laid along the wall, hot at the top and cold at the bottom, with a height of 300-400mm.

15. All sewage pipes and drainage pipes must be checked to see if they are smooth when entering the site, and corresponding protective measures must be taken. All sanitary ware must be thoroughly inspected before installation.

To sum up the above article, I suggest that the waterway should be taken from the top and the circuit should be taken from the ground. Of course, there are various debates on the Internet about whether to go on the roof or on the ground or on the wall. Everyone must learn to distinguish it during decoration.
