It’s amazing how time can change perception. At fifty years, I am sure he never had to thread a piece of 2″ pipe using a block die, but if he had he would never have nostalgia for the galvanized pipe era. And having had workers who “blew” the lead out of a lead pot by inserting a damp or cold ladle, I am not so sure that cast-iron lead joints were the safest either, besides the fumes in a closed room. i will stay with the copper/no-hub/ABS drains of today. Plastic water lines? Their biggest benefit is that it takes little time, skill or experience to install them, which is why it is being used in “tract” housing.
