    Hello, I decided to remove the complete old flange and lead in my concrete basement and have some questions. While hammering the old flange I must have hit the lead? pipe riser and it now has a half inch (from top) hairline crack which is visible on the outside and inside. Don't know if the crack is a problem; surface of riser is still flush and will be partially surrounded by lead. Also, I will be adding back concrete I assume around the flange and don't know what order to do this. I assume I'd lead it first. For now, I have this order planned:

    1) Set flange to proper height; i.e 3/8 inch above floor for 3/8 inch tile.
    2) Fill w/ oakum and lead. How much oakum and how much lead? (too what level) At this point the flange is @ 1/2 inch higher than the riser if the flange is 3/8 above the floor and hope this isn't a problem.
    3) Fill concrete around flange after lead sets.
    4) Tile floor.
    5) Set/secure flange to concrete.

    Any advice is much appreciated. Thanks in advance, Joe

    There are a few different types of PVC flanges that you might want to consider. They go inside the 4" and may block/cover the crack. The crack may cause problems down the road when / if anything leaks out or the crack lenghtens. The flange should set on top of the finished floor.

    Hairline Crack

    Thanks for the advice Cass. I'm coming to the point where I may become a gongoozler because I don't want to mess this up. I'm wondering if there's a way to fix the crack? I'll do some research and maybe call a plumber. Thanks again, Joe

    Maybe I don't understand what you said but lead won't crack.

    The stub looks like steel pipe or cast iron that has been cut with a band saw.

    Either way you need to use a cast iron flange.

    Thanks Plumber1. I'm planning on pouring a lead joint w/ oakum, etc., and hope this all works out. The riser will be about a 1/2 inch below the top of the cast iron flange so I'm assuming I'll pour the lead up to the height of the riser and I will reduce any negative effects of the hairline crack.

    Yes, but you should use a deep flange to grab enough of the riser......
