hi all, I am considering a basement remodel and will need to remove a bath. My question is on how to abandon the waste pipes. I am assuming they are under the concrete (although the bath is up above the basement floor about 10)". I would like to reclaim all or some of this height. I think that the pipes are ABS althought the main vent is cast iron. I guess i could cap them but then I would lose space by keeping the floor up. Are there any problems with capping them? Is there another way to do this and be able to lower the floor back to concrete (without breaking up the concrete)?
Thanks Mike
