Can someone advise me on the differences in above terms. What type of pipe is best for carrying sewage. What type is best for carrying hot water (for shower). And what type is best for carrying drinking water? What are the best brands in pakistan and within those brands what kind of pipes should I buy?
PPR is normally used for hot and normal water. You can use UPVC or PVC Class 5 FOR LONG TERM AND CLASS 3 FOR MID TERM.
