PVC risers and valves for UDS
I have a friend that wants to build a UDS like mine, except he wants to use PVC risers instead of black pipe and PVC valves instead of brass. Does anyone have any experience with using PVC? I have seen images and it looks like they use black pipe 90 degree elbow coming out of the drum and use PVC from there upward. Any issues with heat/melting or transfer of fumes due to heat?
