I discovered last night that our dryer vent has come loose from the dryer. It was just blowing linty steam into the pantry.
There’s a crimped pipe that comes out of the back of the dryer (visible in photo 2), a small elbow (Photo 1) that fits neatly over that, a flexible tube from the elbow down to a solid tube at the floor, and then it heads into the crawl space and out to a vent from there.
The point where the elbow connects to the dryer had no foil tape and no hose clamp. It was apparently just held on with friction.
I fitted the elbow back on, but when I start the dryer, the elbow joint shown in the photo just flies off, which makes sense since there is a lot of hot air blowing straight at it. I added a hose clamp, and tightened it down but after about 15 minutes of drying it also flew off.
I can try to tighten the hose clamp more, but I feel like I’m missing something.
The elbow fits on so snugly that there’s nothing to use the foil tape on. Should I be doing more than just tightening the hose clamp to get the elbow connected to the dryer?
