Can you have copper tubing for a water heater in ST. Louis county?

Question

Please give me the plumbing code and where you got that information(website name, book name...).

Answer 1

copper tubeing is the preferred material anywhere in the U.S.

Answer 2

St. Louis County uses the  "Uniform Plumbing Code."

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

the code is not available in it entirety online, and it is very expensive to purchase the book over 100$!
