I am finishing a bathroom in my basement and was just getting ready to attach the toilet flange when I discovered, after removing the cap on the rough-in, that there was concrete in the drain pipe. The pipe drops vertically about 1' and then does a 90. I can see concrete approximately 1/2" thick in the 90 and running in the direction of the horizontal portion of the pipe downstream from the 90. I assume this concrete is from the initial pour of the basement floor when the house was built. There is evidence of the concrete running down the 1' vertical section and into the 90. Does anyone have any ideas as to how I can remove this concrete? I don't want to break the pipe because I just finished tiling the floor!
Thanks!
Thanks!
