A spot repair can make sense when one accessible fitting fails and the surrounding pipe is healthy. When an older under-slab run is corroding or has leaked more than once, another patch can leave the rest of that buried line ready to fail.
A re-route takes the damaged supply run out of service and places the replacement along a path that is easier to inspect and repair in the future. The right route depends on the home's layout and may use copper, PEX, or a combination approved for the connections involved.
Every new run should be properly sized, supported, protected where it passes through framing or concrete, and pressure-tested before the access areas are closed.
