Hi, my kitchen sink was draining very slowly so I called a plumber to look into what could be the cause. He used a camera to show me that the cast iron pipe was broken and I would either have to have the pipe replaced (about $6700) or have some contraption adapted to the existing plumbing that would basically catch the water from the kitchen sink (bypassing the original drain pipe) and reroute it to the main pipe (about $3500). One's an expensive option, the other a VERY expensive option. I've attached photos of the pipe via the camera he used. I couldn't tell whether the pipe was broken so I was hoping one of you could verify. Additionally, are those prices fair for either option? Thanks in advance for your consideration.
