I want to replace the old-fashioned, leaky boiler drains in my washing machine supply box with Oatey 1/4 turn valves. The old boiler drains are screwed into copper adapters which in turn are sweated on to the 1/2" water supply lines. There is about 3/4" of 1/2" pipe visible before it contacts the black plastic grommet in the plastic wall box (typical plastic box for washing machine supply valves/drain fitting).
Do you think I can unsolder the old fittings and sweat on the new valves if I put a heat shield around where the pipe comes through the grommet in the box? Or do I need to open up the wall?
