Title: Re: Copper steam line soldering
Post by: Stoker on May 22, 2025, 07:49:53 pm

With a bit of the right flux, that should go back together fine, but I'm not sure if trying to add lead free solder into what is already there is a good idea? I suspect that it is not!

Title: Copper steam line soldering
Post by: jkbixby on May 22, 2025, 06:09:17 pm

I should know this......but I don't.  Can copper steam lines be soldered with Oatey #53062 Safe-Flo Lead Free Plumbing Wire Solder which has a melting point of 420 - 460 degrees Fahrenheit ?  Also as shown in the photo, can the two pipes of different diameter which came apart during disassembly be soldered back together as before or is this too dangerous ? I wish the piping and fittings were of a more standard size and that I could silver solder them.
