Installing a bathroom exhaust fan and the proper way to vent it...
All,
I need a little advice from those that have installed bathroom exhaust fans and the proper way to vent them. I am in the process of deciding if I should just vent the fan into the attic or cut a hole/holes in the soffit and have the ducting terminate at this opening. One other option is to install a pvc T fitting in an existing plumbing vent and have it vent through the roof. Is the last method acceptable in most areas as far as the building codes? If I drill 6 or 7 1/2 inch holes in a 4'' diameter circle through the aluminum soffit and tape the end of the fan duct to the soffit at this location, will thismethod be sufficient to vent the fan? The problem I have is that the roof line is about 35-40 feet high so the only way I can access the soffits is through the attic. thanks |
