    I'm trying to seperate the 1/2"copper tubing from my moen tub filler valve assembly. I was able to remove the copper from the brass "filler" tube, but cannot remove it from the brass "valve" tube. It looks like a sweat connection, it seems hot enough and touching solder to it melts instantly, but it is not loosening up. Are there "factory" welds, or do I need a different torch or something?

    Help, thanks!

    hot hot hot

    Are you talking about a Moen roman tub faucet?
    If so, I believe they come from the factory with the short pieces of copper already installed in the sides and bottom of the valves. So the installer is to assemble them with a tee and short copper tube for the tub spout. Since this requires the installer to make sweat connections within 3"-5" of the factory connections I would imagine these factory connections are brazed or at least use a joining material that has a higher melting point than that of your standard solder. If you haven't ruined the joint, then I would just use sweat fittings to extend the nipples as you want them.

    Some of these faucets come completely assembled on 10" centers.

    yep - then I need to replace them :(

    Darn, I was fooled by the easy to remove filler connection. I not only cut them too short, but I'm sure I overheated them as well. So - are replacements going to cost as much as a whole new setup?
