Venting

I purchased a new (well old) home (actually it’s a townhouse) several months back and finally have moved into the one and only bathroom. I made sure that when the electrician came in he wired 2 switches on the wall and left a wip in the rafters so I could install an exhaust fan. I finally cut the hole and it fits very nicely into it. I connected the power and boy does it work well. I the attic is directly above the bathroom and is currently unfinished and will remain that way. It looks like there is blown insulation up there currently.

Here is my issue:

I have the switch taped off now because I am concerned that I obviously need to vent the air outside. I know that just venting into the attic could over time create some really nasty mold. There are currently 2 air vents opening to the outside and I was wondering if I were to use some flexible dryer hose to run from the fan into some elaborate PVC contraption that will utilize one of the existing vents. Again, I do not want to be cutting holes into the roof.

Thanks for the help.

Have you read the vent's installation instructions to see if 4" duct is Ok to use with it? Regardless, you'll have to check local building codes and find out what those other ducts are for, but I very much doubt such an installation would be up to code or even advisable at all.

The two vents I was speaking about are just open vents in the roof cooling the attic I guess. They are providing no other purpose other than that.

I would actually need to use a 3 to 4 inch PVC adapter to make it work, as the feed from the bathroom is 3 inch.

If you're going to block one of them off with the fan's exhaust, I would assume it would not longer work for the attic? I can't see that being a good thing if they were needed in the first place.

Have you read the vent's installation instructions to see if 4" duct is Ok to use with it? Corrugated vinyl dryer duct is not ideal for any venting. The corrugated design can trap moisture (or lint in the case of dryers) in the folds which can build up and cause problems.

Ahhh. I guess that would make a lot of sense. Perhaps I might have to break down and read the instructions then. Thanks for the help.
