I have a whole house humidifier, unsure of exact brand, but it the same as either an Aprilaire 224 or 440.
My question is the water seems to continuosly run through the system even when the furnace isn't on. Is this normal? I normally leave the fan set to ON, because I like the airflow and I don't seem to get cold pockets throughout the house.
I recently, within a month or two, replaced the valve, because the old one was sticking.
I'm not sure where the humidity is set to, but I can check when I get home if that matters. It doesn't seem to be overtly humid in the house and I know it is set a little below normal, because the dryer air was giving my 3y/o nosebleeds.
