I watched his helper solder a couple of joints and realized that was no issue, so after the rough plumbing was completed I took over. Kitchen, upstairs bathroom, outside tap and water to the barn, which included a drain back to ensure the pipes were empty of water above the frost line.
It ain't rocket surgery.
The hardest job was extending the septic field about ten years ago. Getting the slope correct with my little tractor and loader, then getting the coarse rock in place before cutting into the existing field took some measuring, but everything came together as planned. Beginner's luck.

Getting the water to flow down hill isn't the trick in my view. The trick to plumbing, at least for me is to get consistent pressure and flow on the supply side by reducing pipe sizes and the opposite for proper ventilation on the sanitary side.
When I did my house it wasn't comfortable learning that math so I hired out the roughing and did the trims myself.
