Experience Life Experience? Hmmmmmmm! Ran away at 15 and joined a carnival, Navy at 17 Merchant marine at 19 I've had a hellava life.
About 2 yrs ago I bought a house that is about 10 yrs old. While looking around in the attic recently I pulled back some insulation and found that the bathroom exhaust fans were both vented into the attic ! Actually they were blowing directly into a bat of insulation. There is no vent hose attached, and there isn't even an attachment plate on the fan itself to attach a hose. It has been romoved.
I have 2 bathrooms, back to back (1 in the master bedroom, 1 in a hallway), so the fans are relatively close together. Both are vented into the open attic.
My question has 2 parts. 1. Will venting hot, steamy air from the bathrooms into the attic eventually cause problems with mold or rotting of the ceiling joists? And 2. Would it be okay to tie in to the vent pipe running from both bathrooms up through the roof. I thought I could run a flex hose from each fan and put a "T" into the vent pipe, then a "Y" fitting to accept both flex hoses. But I didn't know if this was acceptable. What are your thoughts ?
Answer Good morning Gary, Good questions. If you live in a warm climate such as I do then your attic is ventilated, Sometimes with louvers and sometimes with a attic fan. There is air flow and the moist air will exhaust to the outside. Both my bathroom and the kitchen fan exhuust into the attic and in the 49 years that I've lived here there has been no mold or wood rot problem. However If you live up north where the attics aren't ventilated I can see where there might be a problem. Your idea of running each bathroom fan to a common vent cap on the roof has merit and most certianly will work out just fine. Hope this helps and thank you for rating my reply. Tom
