When original materials are unavailable, coastal exposure adds another reason to review replacements carefully. A visually similar part may have different compatibility or warranty implications. Repair selection should consider the complete assembly.
What to do next
Ask how the proposed replacement was evaluated and whether manufacturer input is needed. Document any differences from the original system. Keep those records available for future maintenance so later contractors understand the repair rather than assuming all components are original.
