Bathroom Exhaust fan install question
Posted by peter on July 29, 2004 at 15:04:01:
Hi-I am working on putting a bathroom in my basement. The room was roughed in. I am working on the exhaust fan. I can only find a 1 1/2 inch white pipe that looks like an exhaust and is close enough to where the bathroom is, to be the exhaust (it is very close to my furnance, but nothing is attached to this piping). My question is all exhaust fans seem to come with a 3-4" aluminum piping. Do I need to purchase a step down aluminum 3-4 inch to plastic 1 1/2 inch or is this not the exhaust piping?
