Development
If the leak is at the joint between the header and a riser, it must be rebrazed.
Carefully remove any absorber fin which covers the leaking joint. On some
absorbers it is possible to use the "feather of a torch on the back side to melt solder
holding the fin on the tubes, then bend the fin back. On other absorbers, careful
work with tin snips will expose the joint.
The joint must be thoroughly cleaned and rebrazed (Figure 5-7). Use phoscopper or
silver bearing brazing alloy. Do not use solder! Even silver solder will not hold up to
the combination of temperature and mechanical stress this joint undergoes.
