Caught a hidden flue leak with a shop vac trick...

Had a job last week where smoke kept backing up into the living room no matter what I did. Tried sealing everything traditional but finally hooked a shop vac to the cleanout and pulled a bead of old mortar right out of a hairline crack in the liner. Anyone else use negative pressure to find sneaky leaks?

Yeah my shop vac found a leak once but it was just me forgetting to turn on the fan.

Ugh, been there, it's always the little things that get you.
