Pipe corrosion: what stains and repeat leaks can tell you
Separate visible pipe damage from assumptions about water quality. Know what to record before requesting a pipe inspection in San Diego County.
John Ciampoli Plumbing · Updated
A stain does not identify the cause
Corrosion involves a reaction between metal and its surroundings. Pipe material, water chemistry and installation conditions matter; being near the coast does not establish why an indoor pipe failed. Blue-green or rusty deposits, damp joints and repeated pinhole leaks deserve inspection. A photograph alone cannot establish the condition inside a pipe or the safety of drinking water.
Record the pattern before a repair
Note the affected fixture, whether discoloration occurs with hot or cold water, when it began and any earlier repairs. Photograph only accessible piping without disturbing deposits or opening a wall. Report active leaking promptly. If water quality has changed, contact your water supplier as well; testing and an inspection answer different questions.
Choose a repair from evidence
Ask what evidence supports a local repair versus replacing a longer section, how matching materials will be selected and what access or finish restoration is involved. Keep a record of repair locations. If lead is a concern, use your utility's guidance and appropriate water testing rather than judging by color.
