Hi, I'm in the process of installing a new, homemade shower pan (thanks to the help of other posts) but am still in a dilema of how to install the new clamping style drain. I currently have a regular drain (cup with grate) embedded in concrete. I would love to have some kinda simple adapter but fear I need to remove the old drain.
Some people recommended I just jackhammer the whole thing, trying not to break the drain pipe. Is there a safer way (i.e. chisel?).
Should I expect when I get down the 2-3" that the drain will simply unscrew from the existing pipe as well?
Thanks in advance.
