Need to Thaw Frozen Pipes Near Record Toronto Saturday March 3rd 1934 Interestingly the 1930's plumbing that we've uncovered was well executed and the materials were in very good shape considering their age. A neighbour from a family of construction workers pointed out that frozen pipes would have been a very big deal, this house and many others back then relied on radiator heating. I'm pleased to say that the old rads are still in very good shape.
