I always thought traditional copper runs were the only way to go for reliability... until a client's basement flooded and we had to re-pipe everything. Watching the pipefitters install a PEX manifold system was eye-opening; the flexibility and ease of repairs were incredible. Now I see how it can save time and reduce future headaches, especially in tight spaces. Honestly, I was stubborn about the old methods, but this experience totally shifted my perspective. It's made me appreciate how trade innovations can really improve outcomes.
