The Best Way to Joint PVC and ABS Plastic Pipe

If you’re plumbing in a new drain or vent and have to join two different kinds of plastic pipe, black ABS and white PVC, don’t assume that you can simply glue them together. Most plumbing codes don’t allow ABS pipe to be solvent-welded (glued) to PVC. Check with your local plumbing inspector.
