What is the consequence of not removing rust from pipes before repairs?

Neglecting to remove rust from pipes before undertaking repairs can lead to significant issues. Rust acts as a corrosive layer that weakens the integrity of the pipe material. When repairs are attempted over rusted areas, the compromised structural integrity can lead to poor adhesion of repair materials, resulting in failed repairs. Additionally, rust can create pockets of moisture and facilitate further corrosion, which compromises the strength of the joints and connections. This situation not only makes future repairs more difficult but also poses safety hazards and inefficiencies in the distribution system. Thus, addressing rust prior to repairs is essential for ensuring the durability and reliability of the repair work.
