Plenty of fun and good times for all! This failed connection under this home was due to corrosion caused by electrolysis. Whenever you transition from copper to galvanized, a dielectric union helps transition the two differing metals and helps prevent electrolysis from occurring. Unfortunately, the original installers of this line did not utilize one, and as a result, the metal burned a hole in it and added just a bit of water to this homeownerâs crawl space. In making the repairs, we were able to eliminate the galvanized all together as the service lateral coming in from the street turned out to be copper, with about 10 linear feet of galvanized between the end of where they brought the copper in, and where the existing stop and drain is located. In eliminating the galvanized section, we now have copper going straight into a brass stop and drain, thus eliminating the non compatible metals that creates electrolysis.
