Silver solder on previous soft solder joints
I have a broken pipe going into a T-connector with sweated soft solder joints. The plumber told me that they now only use silver solder which uses higher heat and would damage the other two soft solder joints.
The plumber proposes to cut out the T-connector by cutting and connecting into the copper pipes feeding into it.
However it feasible to heat the T-connector, break the other two soft solder joints and remove the and replace the T-connector. But will the new silver solder joints be strong on copper pipe where there has been a soft solder joint.
