I'm sweating a Moen tub rough-in valve assembly. here is a link to the assembly: Moen part # 4999
The tube from the each valve to the "T" are heavier gage 1/2 copper. I have a short standard 1/2" copper piece between the "T" and the outflow tube.
When welding the T fitting, the solder doesn't seem to want to draw inside. On the "hot" side, it sucked in, and on the outflow side, it sucked in, but on the "cold" side, it just seems to melt at the edge of the "T"... and not get drawn in.
I had the whole thing assembled, then installed, and the "cold" side leaked (my first leak ). I tried to sweat it again, but it didn't hold. A small fracture was apparent between "T" and the solder bead on the outside. So I took it all apart, cleaned, reamed, and tried to resolder with a fresh "T". Same problem, and again, on the cold side.
What am I doing wrong? When has a fitting had too much heat? Why won't it draw in? I've welded hundreds of joints, and have never had this problem...let alone on the same joint twice.
Thanks!!!
