I am finishing installing a gas water heater and am working on a 3/4" copper escape line from t/p valve. I am trying to connect to anexisting line going through an interior wall and only have 1 1/2" exposed on this side of wall and it is just no t round enough to allow a copper coupling! Is there a solution to this, a way to regain the roundness needed to sweat a coupling, or use a compression fitting of some kind? Brad
