most people know that black pipe is "ABS"( Acrylonitrile-Butadiene-Styrene (ABS for short)).
it is commonly used for running sewer and waste water in houses
it would not be wise to use this because it isn't pressure rated
what i said was that you could buy a white PVC ( pvc (polyvinyl chloride) pipe) 90 and dye it black with rit dye :idea:
