Selection of hydropower pipeline and switch socket

Every local popular brand is different. Moreover, according to the different pricing of manufacturers in different regions, the price in each place will be different. I have run a store of water and electricity decoration materials, and I have been rushing to build it recently.

Water supply pipe: PVC water supply pipe is recommended for exterior wall, and PPR pipe is recommended for interior. An important reason for this choice is because of the economy! PVC water supply pipe is much cheaper than PPR pipe. It is suggested that pipes with pressure of 1.0mPA should be used uniformly. If you build your own house, there should be no problem of hot and cold water. So 1.0MPA should be enough. Of course, if there is consideration, you can choose 1.6mpa pipeline. PPR pipeline is not uv-proof and afraid of light, so it is better not to be an outer pipe. GB/T 10002. 1-2006 is the basis for selecting PVC water supply pipes. It can be seen on the outer wall of the pipeline, which is the only basis. As long as manufacturers stick this logo on their products, they should consider it.

PPR pipeline company. In fact, in my opinion, there is no difference in essence. If you consider it purely from the economic point of view, miscellaneous brands can also be used. If you can afford it, you can consider Wei Xing and Kinder. Actually, don't listen to PPR, the plumber. It's hard to tell the good from the bad. Problems after selecting qualified pipelines can only be caused by the construction level.

PVC drainage pipe: GB/T5836.2-2006 national standard pipe is enough, without considering anything else.

Wires: Is national inspection exemption enough?

Go to the market to see which is cheaper. And it is best to pay attention to copper prices. Buy when copper prices fall!

PVC embedded pipe: the cheaper my choice, the better!

Switch socket: Space God, if we have money, we will definitely use space. It's really beautiful. It's really attractive. This is the price of z ... you can use a miscellaneous brand if you don't require it. Anyway, all manufacturers will replace it in ten years. The low-voltage control switch is selected from Zheng Taihe and Delixi. Anyway, the price of this thing is transparent, and there is not much difference between a miscellaneous brand and a famous brand.

To tell the truth, if I had to choose, I would definitely choose a miscellaneous brand. But judging by the price and workmanship, I will almost buy it.

PS: I'll teach you a trick by the way. When you go shopping, take a scale. The heavier the same material, the better!
