Is it better to use stainless steel water pipes for home improvement or ppr?

I suggest you use ppr tube. The construction is simple, only one hot melting machine is needed, and the labor force is cheap. Compared with stainless steel, labor and materials are doubled.

2.ppr shelf life factory, 10 years is no problem. Although stainless steel does not rust, it may be oxidized and rusted in the supermarket environment in Chongqing.
