My basement has no entry. The pics were taken before floor of kitchen was tiled over, no more access. The shower trap is obviously clogged. As you can see, ancient iron cast pipes.

I want to access basement, clear dirt out and make accessible passage to work on pipes. Only that, my only option right now is, cutting through shower floor for access, pic shows Du-Rock floor with PVC pipe drainage connecting to brass pipes with a rubber connector, my snake can't get passed the rise of the rubber connector to the brass pipe. (?will professional plumbers rotating snake machine cause rubber connector to disconnect? concerned)

Appreciate any comments, Thanks.
