Please give me the plumbing code and where you get that information(website name, book name...).
Answers:    St. Louis County uses the "Uniform Plumbing Code."

Yes copper tubing is standard to supply water to a Water heater, be sure you use the right type (K, L, M, etc.) You should know how to call your local code enforcement or city inspectors office and they will be capable of tell you what is required in your specific nouns.

the code is not available in it entirety online, and it is very expensive to purchase the book over 100$!
copper tubeing is the preferred things anywhere in the U.S.
