Even informed 1950 plumbers properly installed pipes. Then pipes did not freeze even in unheated basements.
Please comprehend what was posted; stop justifying bad workmanship with ignorance. In venues where a frost line is 4 feet, then pipes must be buried more than four feet down. Even a ditch digger knows pipes must always be below the frost line. If not, then pipes are reburied deeper.
If a house is at 40 degrees, then an unheated basement should never have frozen pipes. But some believe failure acceptable. They do not even patch foundation cracks (which are often due to defective workmanship in the footings), do not install missing insulation, and do not replace defective windows. Conditions acceptable only in abandon buildings or the ghetto.
85% of all frozen pipes are directly traceable to a naive or lazy human. Most learn from their mistakes. Since the solution is so simple, so well understood, and easy. A frozen water pipe is fixed so that it never freezes again even in -20 degree (-30 degree C) weather.
A pipe repeatedly frozen identifies a human in denial. Who would lash out rather than admit to why the problem exists.
