Where does my dryer vent?

Hi all,

I am attempting to clean out my dryer vent. I don't think it is clogged or anything, just behind on maintenance. Bought the house 4 years ago and haven't done it yet. I put a vacuum cleaner on the hose and it did not compress like there was a clog.

I don't see what is obviously a dyer vent outside the house, on the roof, or anything. The only thing I see outside is a this vent on the outside of the chimney framing, but it is not the same diameter hose, and I feel no air when the dryer is on. There is no lint buildup on or around this. Sorry photo is sideways, not sure why it isn't rotating on its own.





The basement is all drywalled, and I hate it.

I put a speaker on the hose at the dryer and could faintly hear it through this outside vent, so I suppose it is possible it is disconnected.

One strange thing (please tell me if this is normal)... under the knockout for the fireplace, the inside floor joists are completely open. Under there, I cannot even see this flexible duct coming out or up from the basement, so I don't know how it is ran here.




This video shows where the fireplace is in relation to the dryer.

Any ideas would be great.

 

That looks like a 4" vent line and cap which is the same size the dryer is using. If that isn't for the dryer then it could be some type of fresh air intake for the fireplace.

Can't tell much from the video. Where is the dryer from that vent line ?
It could go under the floor and exit by the fireplace.

 

If you were standing in front of the dryer, the fireplace is about 8ft to the left and behind you.

 

That type of vent could be broken in wall. You will need to pull dryer out and see if that is the same kind of vent that goes into wall,

 

I'm still stuck on this. I'm not sure what to do next. Should I start opening up the ceiling of my basement to trace where this duct leads to? Wait till winter and look for steam outside when dryer is running?

 

Do your clothes dry in one cycle of dryer? If they do than wait till winter to see where the vent is. What you can do now is run dryer and see if you can feel the air flow at the vents. Dryers push a lot of air you should be able to feel a strong air flow.

 

Only another opinion, but I would not want flexible duct inside my walls anyway, rigid instead, so don't see anything to gain by waiting for colder weather. I would start opening things up and see exactly what is there, If you can't feel anything at that outside vent I would suspect that whatever is there is damaged or blocked, and you may be dumping all that moist air into a wall cavity.
