Heating piping embedded in concrete floor for 60+ years.
I recently inspected a split level house built in the 1950s that has baseboard heating in the upper areas, but there are two hot water radiators at grade level. The piping for the grade level radiators is embedded in the concrete floors. Since the system is original and more than 60 years old, I am concerned about degradation of the embedded piping, whether it is external corrosion from the concrete, rusting from condensation or some far out speculation of degradation if the piping could move while in the concrete. I know it is a stretch of the imagination, but thought I would ask anyhow.
Thanks for any advice.
