one building of an apt complex has a break in a cast iron line under it.
instead of busting up the concrete is it feasible to line the pipe?
if it is feasible, is it possible to only line the 1-2 feet where the break occurred?
finally, if it is feasible, the only entry point for the liner is 45 degree schedule 40 cleanout, would that handle the pounding of the ram?
thanks for your feedback.
