I repaired my dryer exhaust, the shitty aluminum foil hose was sheared. Whoever installed the stuff before buried the vent in the wall so I couldn't connect new duct to it.

I ended up replacing the solid duct and the foil hose with semi rigid stuff.

Was I supposed to seal the snap lock duct in the wall? It's only like a 3' run to outside but I'm worried that it'll like... Pop open or leak air or whatever?
