The bathroom fan runs well. model S10U CFM 110 SONES 1.5.
problem is it does not suck ANY air! we wondered if the ducting had a blockage.
included is a few pipes from the room. 2 look the same, maybe one is for the gas furnace and the other is for the bathroom fan which also starts the furnace fan. the little vent is for the ensuite fan - probably.
does it look like a block? where could it be? it is a 13 year old bungalow.
ideas very welcome!
