Hi all! I've been having issues with my plumbing in the L.A. area. My hot water piped busted.1st plumber estimated $550 to patch it or $2,250 to replace the galvanized pipe with cooper. The home is 2K sq. ft and I'm thinking of doing a major pipe re installation. What would be the normal estimates for this time of work? How much to fix the pipe and to reinstall piping? Thanks in advance.
