The main ingredient is copper sulfate and it kills bacteria, algae, roots, plants, snails, and fungi. It's safe to use in city sewer. You can also use it in a septic tank but you would have to talk to someone who has experience using it in the septic tank. I have no experience with septic tanks. As far as copper sewer pipes, I don't see an issue using it on copper pipes.

You're welcome! =)
Thank you, how far can this Zep product goes?
I use one bottle every six months.
Is this for septic or city sewer also, can this be used on copper sewer pipes?
