Is domestic tap water made of iron or plastic?

Plastics are good, and PPR pipes are used more now. Iron is more prone to rust, water quality is more easily affected and service life is shorter.

However, aluminum-plastic pipe is better than PPR in compression and corrosion resistance. However, the cost of aluminum-plastic pipes is relatively high, and the supporting accessories are all copper pipes or pressed parts, which is much higher than that of PPR. Moreover, after a long time of PPR, scale will be produced inside the water pipe, which will breed a large number of bacteria and affect human health.
