Going through the soffit is the right move with the vent.

Tie that shite into the existing exhaust. Don't run a new one.



Well i havent inspected it yet but the ole lady says the existing vent is just venting into the attic.

i.e. there aint no exhisting duct to tie in to.

I hadnt planned on putting in a heater. just a vent and light.


You should be good. It will be on the same switch so you will not have independent control of the light and fan. You can either turn them both on or both off. Also, vent it through the roof and not the soffit.

Oh ok, I thought you did since the other exhaust fan is already there.

Why through the roof? I don't see an advantage, only negatives.

Serious? You really should vent up through the roof.



Well that was my plan but also why i started this thread. Why is one better than the other?
Because soffits are designed to suck in air. All of the air you will be exhausting will be very humid air and once it goes out of your exhaust soffit, it will get sucked up by one of your other, nearby soffits and end up in your attic.

Which im ok with. We never even use that light now so the light and exhaust being on independent switches is not the biggest need.

The fart fan more than likely has a vent, I'm hoping the ductwork is just disconnected.

Makes sense enough but i'm not sure there are any other exhaust soffits on that side of the house. If that's the case would it be fine to go through a soffitt.

That's why I'm hoping it's a matter of it being disconnected, rather than no roof vent at all.

Dude, you can go through the soffit with no problem. You aren't venting a fricking dryer

I wouldn't. And I won't say it would be fine. The correct way is to run a duct and vent it through the roof and remove it totally. Not sure why you really want to take the chance on all of the hot, damp air coming back in your attic.

Well because going through the roof seems much harder for a DYI'er like me.

Maybe he doesn't want to cut a hole in the roof?
