one reason n.y.c. code once stated " uncoated ex. heavy cast iron " . if it was cracked , you could not hide it.

    Can anyone tell me why old cast iron pipes crack. I have replaced many old pipes that split down one side. Not a straight crack - it goes all directions.

    with Bob.

    Had it on many occasions on buildings built in the 50's and it did seem like very thin cast iron.

    It did not seem to matter, either vericle or horizontal. It wouldn't take much to cut it out with the sawsall.

    pipes were installed in the 40's But it took me 45 mins to cut thru the pipe with a carbide blade. The cast iron pipe is about 1/4 thick and the crack opening ranges from 1/4 tp 3/8 - WOW

    I had

    those also. I believe they were a mixture of CI and steel because of the shortages during the war.

    I had one project (for a Judge, no less, who was a wonderful client) which required me to cut a half dozen or more stacks and connect them to the new sewer main that was replacing the line to the sepic system.

    All of them were in a low crawl space where I could not get the snap cutter in. Took forever but thank goodness it was a time and material project and not something I gave a quote on.

    Thanks for the walk down memory lane.

    They may have been cracked from the day they went in and just with wear are showing a leak. When the old timers of less than high standards cracked a piece when cutting it they often just grabbed the asphalt paint and covered up hairline cracks. Even then they had hacks.
    Cost is what you spend , value is what you get.
