I'm hooking up a bathroom fan in the attic. I need to make a sharp bend
in the duct work, and had planned on using 4" PVC drain pipe fittings. I
went to Home Depot, and they have 4" PVC sewer/drain pipe (the thin wall
stuff), but all the fittings they sell are styrene. Other folks do sell
PVC fittings, but if I want to use PVC, I'll have to go hunting for them.
I was wondering what the group's feelings are about PVC vs styrene for
this. The attic is going to get toasty, and I would think the styrene
will get brittle compared to the PVC. As a matter of fact, I was reallly
surprised to see that they were using styrene at all for drain pipes.
I'm also not sure what sort of solvent is needed to glue the styrene to
PVC. I suppose they may assume the stuff just gets forced together
because it isn't under pressure, but that seems pretty odd too.
