I searched your question because I didnt have an answer.....but I have just always used PVC.
"There are four types of plastic in general use. Black plastic, which is ABS,(Acylonitrile Butadine Styrene) and white plastic which is PVC and CPVC,(Polyvinyl Chloride and Chlornated Polyvinyl Chloride) ABS is used for drainage. PVC is used outside the house for cold water feed from the pump or the meter Also drainage both inside and outside the house. CPVC is rated for both hot and cold lines and can be used to plumb a house on the inside and then we have Polybutylene pipe,(PB or Polly Pipe) which is flexible tubing on water piping.:
Hope this answered your question.
