Dryer Vent Size Mismatch
I just moved into a recently renovated apartment. The 3 inch dryer tube feeds into a main vent (4 inch) to the outside. When the contractors attached the tube from the dryer to vent, they just taped it together. Shortly after I moved in, the connection broke and my porch turned into a sauna. I tried to use a circular connector (you screw a screw on the side, and it tightens) but it didn't work.
Is there any way that I can make a solid connection?
