Prevention
Prevention starts with a log, not a product name.
Boards ask how to stop the next pinhole. The honest first step is to know how many you already had, on which temperature, and in which stacks.
Count before you shop.
Date, suite, hot or cold, and whether it was a fitting or a pipe wall. That table is the start of an assessment.
Repipe versus treatment versus sensors.
Those are different capital conversations. Mixing them in one motion confuses owners. LEaC Shield assessment is for recurring domestic pinholes on suitable systems, not a universal substitute for repipe.
Keep repairing the hole in front of you.
Prevention talk does not pause an active spray. Isolate, repair, then put the incident on the log.
Questions people ask
Can vinegar or a filter end pinholes?
Do not treat a building with household chemicals. Water treatment belongs to a designed program.
When is assessment worth discussing?
When the same building is opening new holes, especially on domestic hot and cold copper, and the board wants a building-specific look.
