A visible split identifies the release point but not whether impact, movement, pressure, corrosion, installation, or another condition contributed.
Once flow is stopped, keep the broken area undisturbed enough for diagnosis. A temporary clamp, broad repipe, or insurance claim may each be discussed, but none should be assumed before the pipe material, failed joint, pressure, exposure, and extent are known.
Keep this boundary: A burst location is not proof that every similar pipe is failing. Broader replacement needs condition evidence and an explicit boundary.
