    Bob gave you a detailed answer. Let's see if I can "simple" it out.
    PVC is for drainage and cold water lines. CVPC is for hot water lines.
    Schedule #20 is used in lighter applications with not much pressure.
    Schedule #40 is the most used in water piping and drainage.
    Schedule #80 is used in applications that require a heavier stronger pipe such as a commercial contract would call for. Hope this answers your question and thank you for rating my answer. Tom
