I'm no plumber , so I'm going to ask here . My son needs to run a waterline from the road , to his home that is under construction . He want's to use 1 1/2 " pipe for future expansion to a shop , etc . His question is , what type of pipe should he use ? PVC SChed. 40 ? This is South Louisiana , so frost is not an issue . The run will be about 350 ft.
