How are you allowing makeup air to enter the house Des? I'm concerned about that negative pressure and the furnace etc. I was going to run another 4" duct from the same window that is essentially just an open pipe leading into the fish room.

Also where should inlet air and outlet be positioned? I think humid air sinks so shouldn't the new air vent be up top and the outlet on the bathroom fan be near the floor?

Hey Brett, I never thought about make up air....does it wreck my furnace? I guess my house is a big vacuum then. I guess I could run another 4" duct, but then rodents will get into my house....wouldn't want that.

As long as I don't die as a result of negative air pressure I guess I'm okay...it's been a little over a year like that. I think normal bathroom fans in houses are hooked to the furnace fan to have it kick on when the bathroom fan is on I think.
