Can PVC be used to vent a Dryer


I have a second floor laundry that currently has an aluminum exhaust vent. I was wondering if I can use pvc to vent the dryer so that I can easily install clean-outs (I haven't seen anything that will allow easy access in the aluminum round ducts that I currently have in place). The exhaust line is about 12 feet long with two 90 degree elbows. I am concerned about lint in the line (the dryer is gas) and would like to put in clean-out "y's" to vacuum the lint periodically.

No. The lint flowing thru the PVC will statically charge it making the lint stick to it like a magnet.

there are aluminum "saddle tees" that we use to connect gas water heaters to the side of a main vent pipe which you may be able to buy from a sheet metal shop or possibly HDepot. DO NOT use sheet metal screws as they catch lint, use foil metal tape from HDepot. Looks like this one except the branch part is connected to the body at a 45 deg angle.

I second this statement. Never thought about that until an inspector almost failed me when I did my laundry room in the basement. He let me pass as long as I took out the screws while he stood there inspecting other things.
