What’s under the slab?
Many of the big post-war planned communities and tract suburbs in Burlington and Camden counties were built on concrete slabs, with cast iron drains running beneath the floor. Inside, that iron builds up scale and rough spots over the decades, and grease and paper catch on them. The result is the same kitchen or tub clogging again a few months after it was cleared.
That is why the technician runs a camera before reaching for aggressive jetting: older iron needs the right tool at the right pressure, and the camera shows whether you are looking at buildup that cleans out or something that needs a different conversation.
