I need to run a power cord through an existing concrete foundation. There
is a schedule 40 PVC 1 5/8" ID, 1 15/16" OD waterline embedded in the
concrete that has 2 90degree bends, they are standard 90deg corners close to
each end of a ~20' run. Is there any chance that a standard fish tape would
be able to be pushed through?
