Monkeyboy.. please keep us posted on what you end up doing.. I'm in the same boat..
We have large master bath with a high vauletd ceiling.. in the bath room there's a seperate toilet room that has a window and an exhaust fan mainly for light and for the riddance of any foul odors
Well the vaulted ceiling collects the steam and moisture from the shower (wife takes really long ones.. not sure what's going in there, but that's another story..) We've started to develop small black spots (mold) on the textured ceiling..
So I bought a fan for the main bath area (130 cfm), tapped into electric for the light above the shower. I also ran the flexable ducting down to tie into the venting used for the one in the toilet room... I couldn'y find any Y's made for such an application, so I got a 3" (i.d.) pvc connector that had a straight thru piece and a curved connector coming in.. used large screw clamps to make sure it all good and tight..
Problem now is with the new bathroom fan on, and even though the toilet room fan has the flap in there to stop air from coming in, there's enough gaps in the flap for air to be pushed into the smaller fan (path of least resistance).. the run for the new fan is about 15 feet of ducting before it hits the pvc connector and about a 2 foot run from the pvc connector to the toilet room fan and 2 foot to the outside vent..
If I can't solve it now, I'm tempted to vent the toilet room fan to the attic and use the exterior vent for the new bathroom high volume one that will be used during and after showers.. when the toilet room fan is on, the door is usually shut and little or no moisure is present (again it for odors) and if a shower is taking place, the main fan will be on.
Anyone have any feedback or suggestions... if I vent the one for the toilet room to the attic, it makes sense to have the venting pour into an open area and higher up in the roof space (no directly into any insulation).. the attic space is huge (could dry wall it and live up there if someone wanted to).. a roof vent isn't a good option as it's 2 stories up.. if we hever get any roof repairs done, I'll install a vent then and be done with it..
Thanks for any suggestions!!
