Hello,
I was doing some cable fishing in my attic today and I noticed that
two of the bathrooms on the second floor have their exhaut fans
terminating in the attic. Actually the end of the exhaust duct is
laying on the soffit vent. Is this proper under most building codes?
The attic has good ventilation with the soffit and ridge vents. But I
am still not happy with what the builder did.

I was thinking of using a wall cap and cutting a 5''x5'' hole in the
soffit and venting it this way as opposed to putting another PVC stack
thru the roof. Has anyone tried this before and is it any better than
what the builder did?
