I have a tiny and dumpy house that is ripe for teardown. I'd like to build a house that will last 150 years. I'm all thumbs so I'd like something bulletproof that will last without any repair. What should I do about plumbing? Here are some of my ideas, please improve on them.
1. Use copper water lines. Most longevity? Anyone install grade L copper plumbing inside?
2. Should I use 1 1/2 inch in baths instead of 1 1/4?
3. Place hatches (?) on the walls with plumbing so you can access it without knocking a hole in the wall?
4. Limit plumbing to a small area of the house so pipes aren't everywhere?
5. Water heater ideas? Hot water recirculation pump? (We have one at work).
6. Place floor drain in the basement?
