I have a Panasonic Whisper Warm 110 CFM exhaust fan above my shower.
It works great BUT it recently started to drip when on while shower hot and outside cold. At first it dripped thru the unit, now its dripping at drywall where the exhaust pipe meets unit. The exhasit pipe is 4" duct and travels about 1-0 before it 90's up to roof another 1-6 and out. I understand rules of condensation just dont understand how to beat it.....
I wrapped pipe in insualtion but only about 1/2 thick.....
any insight or ideas ?
thanks much
