I want to replace my Main Water Line myself. The current Line is 50+ years old and is galvanized pipe (3/4"). I Live in Southern Ca so frost is not an issue and the run is about 35' to 40'. I wanted to use copper pipe to match the pipe in the house. I heard that mixing galvanized with copper needs a zinc connector and do not see one in the original conection. To be safe should i install one at the meter since the city pipe is most likely galvanized. And in addition i was thinking of wrapping the copper pipe with something to increase its life. Any Sugestions? I see wrap on buried gas pipe and thought there was some material used on water pipe buried as well. Thanks
