Have a house with a 6 foot double wall vent exhaust vent pipe in the attic, but the bottom stops about a foot above the floor. There is NO heater etc to connect it to. The pipe penetrates the roof and exist fortnuately to a vented cap, not just open hole.
Aside from bugs and drafting, is there a problem here? The insulation below it wasn’t espiecally dusty or showing signs of damp but is this an issue just being open?
whats the name of the type of cap?
