I just moved my dryer (gas) a couple feet to a better location in the basement. It is actually now closer to the existing dryer vent to the outside of the house. The previous owner has it connected with about 15 feet of 4" flex tubing. Now I don't need that much so I was going to remove some of the existing flex tube.
It was hooked up with 2 or 3 sections of flex tube. With the dryer in a new location I can run the vent pretty straight up and then over to the hole in the wall. I bought some 4" rigid aluminum tube to come out of the dryer and then I connected that to a 4 foot long piece of the old flex tube. I used the metal strap with a screw that tightens around the tube (not sure what it is called).
Is this the correct way to connect the flex to the rigid one and the actual vent in the wall? Do I also need to tape over this connection, if so what type of tape? I seem to recall that duct tape should not be used on ducts, though I am not sure if it is OK on a dryer vent.
Do I also need to tape around where the rigid tube meets a rigid "elbow" that comes out of the dryer?
