Chances are the pipe was eaten away by the concrete. Old radiant heating used
copper pipes buried in the slab. Concrete is a base (opposite of acid) and
slowly eats at copper. Very interesting, the systems failed in about 40 years.
Now all pipes running through concrete are plastic or routed through plastic
chases.
Karl should bite the bullet and reroute the pipes through the wall. He should
also expect to reroute more pipes in the near future.
