Bathroom Fan Venting Question
 
Hello everyone,

This is my first post and I'm new to this forum. I'm looking forward to learning from some of you in the future!

Any help someone could provide on properly venting my bathroom fan would be most appreciated. Currently my bathroom fan is vented straight to the attic. I've read a lot of opinions about venting to the soffit, but that's not really an option for me anyway because my attic is so small I can't get to them from the inside.

My question has to do with an old black boxed roof vent that is no longer in use. Please excuse my lack of knowledge with terminology as I am only a year into DIY projects. There is a larger black vent in my roof that has a metal tube coming down to the attic. The tube stops about two-three inches from the ceiling and drywall is under a hole where it appears to have been used in the past. I'm assuming that a refurb was completed and the vent was no longer required.

Would be it appropriate to assume that this vent would still work and could I simply buy duct to connect the fan to this vent? The metal tube is wider than the duct would be, what would be the best way to connect them? Are there any potential concerns with this type of connection? Also, I would need to cut the tube since it's so low to the ceiling... would using a rotary saw be a good tool for this?

Thanks ahead of time for your response!

Yes,you can certainly use that vent.
If you feel you need to cut some of the duct off,a pair of tin snips will do it.

Yes you can use it providing it is still in good shape. Just run your new duct to it and, if need be, attach with a reducer. I prefer solid duct and don't care much for the flex tubing but that's not my area of expertise.
A good pair of snips is all you need to cut it.

As far as your old one, if it's not leaking then leave it. it's not hurting anything.
