Yesterday I saw my cousin Andy the plumber at the store and he asked if the water leak seeping out on the concrete slab foundation of my house had stopped since he'd worked on it. Most of it has, but there's still something going on there. I hate to look.
Anyway, we got to talking about WHY houses are built with something as important as plumbing put under the slab, and a house built on top of it all? It makes much better sense that plumbing pipes be run through conduits in the wall or in a crawl space where plumbers could get to them to repair them.
If I ever had a house built from scratch, it would have easily accesible plumbing pipes and it would have metal bones instead of the typical wood framing. Metal infrastructure would be much stronger--I saw a home under construction in Mobile Alabama being built that way. I liked the way that looked. Oh well, when I win the lottery, I'll start building my perfect house right away, Ha Ha! Susil
