I have some decent ideas as to why, I’m asking mainly as a hopefully fun contribution here, and to maybe learn some interesting plumbing info!

    I work in construction and will give you the common viewpoint (non-US).

    We use PVC pipes to drain used water and PPRC pipes to supply fresh water to flats in an apartment. These are all installed to be practically permanent. The concrete is put in place on top of these pipes.

    I imagine hoses can be used for the same purpose, but the price would be simply higher and no investor would prefer hoses over pipes for this reason. If there is a type of hose that is as effective as these pipes and as affordable, it’s not available in my region
