They got in the insulation inside the band joist (that's the very
outside joist, between the first and second floors).  Stan's working
on the manifolds now.  They're a fancy tube with lots of brazed-on
pipe fittings.  They distribute the heated water around the floor
tubes.  Each tube has its own ball valve.  At least one of the
manifolds is in.  Stan wants to get the manifolds in, and the tubes
pressure-tested, so he can see if any of them leak before the guys
start to put the reflective insulation under the tubes.
