Can anyone tell me what issues should be paid attention to in home improvement and plumbing projects?

Hello, water and electricity decoration is an important part of home decoration. Everyone knows that water and electricity decoration is a hidden project. If it is not installed well, it will be difficult to maintain later, so you must pay a lot of attention during installation. Don’t try to save money to buy bad pipe fittings and wires. It is recommended to choose branded ones. Let’s take a look at what issues you should pay attention to in home improvement and plumbing projects. 1. Regarding the wires used in home decoration, some owners and friends pay special attention to them and think that they must buy the best ones, but I don’t think it is necessary, as long as the quality is passable. According to my home decoration experience, there are very few cases where warranty is required due to wire problems, because according to current construction standards, the safety redundancy of wires is very high. Generally, a 1.5-horsepower air conditioner uses 2.5 square meters of wires. In fact, 1.5 square meters of wires are used. There will be absolutely no problem with the wires. Therefore, there is no need for the owner friends to spend too much money on wires. The home decoration habit in Hangzhou is to use Zhongce wires. If the owner friends use wires from other regular manufacturers, there will definitely be no problem. 2. The network cable must be used well, because the copper wire in the poor network cable is too thin, which will lead to poor contact between the crystal head and the possibility of network disconnection. Sometimes it is mistakenly thought to be the cause of routing and other network equipment. But good network cables are not necessarily more expensive, especially shielded network cables, which are not necessary at all. Our general civilian networks are insensitive to interference and can almost be ignored. What owners really need is unshielded quality. Better network cables, never buy shielded but poor quality network cables. 3. You can just buy ordinary cables for cable TV, telephone and audio cables, unless the owner’s friend is an audiophile. 4. For water pipes, I think Weixing’s green pipes are fine, but don’t differentiate between hot and cold water, just use hot water pipes. It’s best not to use Piersa, there are so many types of Piersa who knows which one is real. If the owner friends are rich, I suggest the owner friends use copper pipes. Copper pipes are recognized by professionals as the best water pipes, especially for hot water. All five-star hotels use copper pipes 100% of the time. Civilian water supply pipes in Western developed countries are basically used. All use copper pipes. The reason why China's domestic water pipes do not use copper pipes is because we cannot afford them. In foreign countries, PPR pipes are generally only used in agricultural fields and temporary water pipes. If we cut open a PPR water pipe that has been used for a year, you will find a layer of greasy black dirt attached to the wall of the pipe inside, which is disgusting to see. Unfortunately, the price of copper pipes is too high for ordinary people, so we can only make do with PPR water pipes. 5. I don’t think it’s a big problem whether the water pipes should be routed from the roof or from the ground. The cost of going from the roof is higher, and the construction will be more troublesome if there is no suspended ceiling. The advantage is that in case of water leakage, it can be discovered in time to reduce losses, but the probability of water pipe leakage is high. Not high, unless broken manually. If you want to walk on the ground, you must pay extra attention when drilling. 6. The triangular valve and hose must be used in good condition. If they burst, the consequences will be disastrous. 7. The direction and position of the drainage pipe and floor drain are very important, otherwise the water from the washbasin and washing machine will easily overflow from other floor drains. The floor drain must be anti-overflow type. 8. The outlet of the water pipe must be installed flat and of suitable depth. The outlet must be kept perpendicular to the wall. A standard distance of 15cm between hot and cold water must be maintained. Otherwise, it will affect the installation of the faucet, and in serious cases, the decorative cover of the faucet will not be covered. The water outlet at the back affects the appearance. 9. The wire box of the switch panel must be installed flat and of appropriate depth, and two adjacent wire boxes must be kept at an accurate distance, otherwise it will affect the installation and appearance of the switch panel. 10. It is right that strong and weak currents should be wired in different conduits, but it is absolutely unnecessary to separate strong and weak currents by 40cm. Doing so will increase the cost a lot, and it has no meaning for actual use. The main purpose of separating strong and weak electricity is to reduce the interference of strong electricity on weak points. In fact, it is completely negligible for ordinary households. The separation of strong and weak electricity is only meaningful for those military and scientific research tasks that require extremely high requirements. What can really interfere with weak current is only at the interface. The arc generated by the switch and plug-in of strong current will interfere with weak current. The interference of the wire itself is very little. Strangely, many times the switch socket of strong and weak current does not interfere with weak current. They can be installed side by side. The strong and weak current interfaces on our computers are often close to each other, which means that there is no problem in installing the strong and weak current ports together, and there is no problem in sticking the wires together. I really don’t know how the current home decoration construction regulations were developed. They are so inconsistent with the reality of home decoration. 11. The load of strong current lines must be distributed reasonably.

12. Weak current must be concentrated in a fixed, concealed place with good power and heat dissipation, and then uniformly distributed from here. In this way, routing, switches, modems, telephone switchboards, and cable TV distributors can be installed together, which is both convenient for installation and debugging. Easy to maintain and adjust. It is recommended that owner friends not buy so-called smart information boxes, which are not only expensive but also impractical. You can buy routers, switches, modems, telephone switchboards, and cable TV distributors separately, which are cheaper, more powerful, and have very good scalability in the future. . 13. It is completely unnecessary to separate red and white tubes for strong and weak currents. This is a typical image project of a home improvement company. 14. It is best to use under-counter basins for kitchen and laundry sinks, which are convenient and hygienic to use. 15. There should be more sockets rather than less, especially don’t leave them out. It is very troublesome to add sockets after the tiles are laid. 16. If possible, it is recommended that the owner should install a urinal in the bathroom. Men standing next to the toilet to urinate will inevitably make the toilet dirty, especially men with poor prostates. Therefore, if you want to keep the toilet clean, you must install a urinal. . 17. If it is a circulating hot water system, all hot water pipes must be insulated. If not, there is no need to insulate. And for the vast majority of ordinary home improvement owners, it is impossible to use a circulating hot water system, so there is no need to insulate. Now I find that many home improvement projects insulate hot water pipes, which is really unnecessary. The above introduces the home decoration and water and electricity engineering matters in detail. I personally recommend that you choose better materials when purchasing this material, so that the quality can be guaranteed. Don’t do it just to save a little money. You know what you save now will be better in the future. Maintenance costs more. I hope my answer is helpful to you. If you think it is helpful, give me a thumbs up. I will answer more carefully in the future. I wish you a happy life.
