How do I connect 2" PVC to a 4" corrugated pipe?

Visit a plumbing section of Lowe's or other well stocked store that
carries plumbing supplies and ask the person who works the plumbing
section. Most of the time you can find an adapter that works from 2"
to 4" and seals tightly. All pipes and tubing aren't the same, but
the guy in the plumbing section will probably know.
