New bath fan..

Am installing a new bath fan in a bathroom that's never had one.I do have a number of existing roof vents.Would it be alright to run duct to existing vent?As always..would appreciate any insight..(located in Washington State.)

Re: New bath fan..

It depends upon code in your fair city.

The concept to operate from is very straight forward - You don't want to be pumping humid hot air into your attic. That in mind, think about the wind blowing outside your house. Is there a possibility the wind can blow backwards down one of these old openings? If yes, then the moist air from the bath will not be properly vented.

Ideally you want a separate, one way vent to the outside.

Re: New bath fan..

A bathroom vent is different than other vents, and therefore should go from the fan unit to the outside, not into another vent.
