Carrier tactic
“Pre-existing wear.” The pipe was corroded or past its service life.
Our rebuttal
Carriers love a “this was already worn” denial on copper and galvanized. We rebut with date-stamped pre-loss photos, the licensed plumber’s source report pegging the failure to a single event date, and the pipe-spec / install date pulled from the Pennsylvania UCC permit record. If the system carried for decades without failing, “pre-existing wear” is a stretch the contract did not write.
