Dryer venting freely into attic


While crawling through my attic to run ethernet cable, I found the vent from my dryer freely blowing into the space. 40 years of lint not caught in the trap is all over.At first I thought the duct must have just come loose but, upon further inspection, there is no ducting for the dryer exhaust. From the dryer is a 4”x 3” rectangular duct running up the wall behind the drywall . Then multiple 2” holes are cut through the what I think would be called the top plate. The 4”x3” ducting looks to just be slammed into the hole. Looking down from the attic the lip of the ducting is bent, further restricting ventilation. Luckily, there is a 3” duct about a foot or so away . It is connected to an exhaust fan that is over my pantry which is rarely turned on.My initial thoughts are to cut the 4”x3” rectangular duct and fit a 3” round flange which I could then hopefully fit a connection through the 2x4’s. I could then either use the 3” duct from the exhaust fan or, if it was safe/okay to do so, split the duct so I could still have a functioning exhaust fan.As a side note, my washer and dryer are in the garage. I cut open the drywall to access the vent after I found it.Is this common or did the builder just get lazy? Thanks for any advice or help you can provide.https://imgur.com/gallery/S41SLnt[pictures ](https://ift.tt/2og8IA7)
