One of my sons-in-law just installed a new stop & waste valve. It is leaking in a place that seems unexpected.

If you look carefully, you can see that it is weeping at the seam just to the right of the hex portion. Any thoughts? Can that be taken apart?
Disclaimer: if the subfloor above looks charred, that would have been done by some previous plumber. No soldering was done in place on this job.
