no exhaust fan in New England small bathroom
While we are on the subject, might I also ask a bathroom fan/exhaust question. I don't have a fan in the bathroom of my small old (70s) nothing fancy home. The problem is mildew or mold, whatever that black stuff is the grows on the ceiling. A couple of years ago, a very kind painter painted with KILZ underneath, which stopped it for quite a while.
As other people above, my fear about putting in a fan is that, although this is just a very inexpensive house (basically a tract home), it is very very tight against the very very cold NH winters. And I don't want to interfere with that. I guess a fan could be put in to exhaust either directly out (through the wall), or up into the unfinished attic, or maybe even down into the basement/garage. Any advice or thoughts would be very useful in terms of not having this turn into a fiasco. Thanks! R
Bathroom fan makes popping sound when windy outside
The exhaust fan in my upstairs bathroom makes a popping sound every 5 seconds or so when it is windy outside. I'm assuming that this is caused by changes in air pressure lifting and then dropping the backflow preventer flap. Is there an easy fix for this problem? The exhaust tube goes up, then does a 90 and exits on the side of the house. Thanks for the help!
