Does a vent have to be a straight run or can it incorporate 90 degree right angles? I'm re-doing a shower stall; one wall is going to be glass block...right in the middle of that wall is a vent, so I'm wondering if I can simply re-route the vent to the other side of the stall using 90 degree connections and then up to the attic to meet up with the existing vent there?
thanks.
thanks.
