    They have defferent melting points, so I'd say no. Can't remove the old solder?

      The silver melts hotter than normal solder. BUT, impurities in the old solder/joint/pipe may cause problems with the flow of silver. It is possible, I've done it. Usually it's easier to do it the right way.

        Yes I do know big difference in temp. I have to get the copper cherry red before it will take the Silver solder .
        Dumb question !

          I figured you knew about the temp difference but I didnt know if you knew that the hotter temp could create the slag/inclusions in the old solder.

          No question is dumb.

            Yes, Either add soft solder to the joint or Silver solder (Braze) over the soft solder... Keep in mind ANY moisture in the pipe will make for a frustrating day if you attempt to braze.

              pretty simple to do, unless your fittings are brass.

                Why can't it be fixed conventionally?
                Buy cheap, buy twice.

                  Ben I have one joint , that after 20 Minutes It will grip occasionally ! Drained down twice and re soldered. I also, use My wet vac to purge out any water ! Driven Me nuts . Of course I'm using 95/5 solder. Question, would it help to go over the joint with 50/50 solder ,because of the low melting Temp. ? Thanks Tool

                    Cut the fitting out and redo it.
