My house was built on the cheap about 35 years ago, with little or no inspection during the build.

I have been Roto-rooting the Sanitary drain once a year, (Approx.) for the past 20 years.

It seems like it would be useful to get a Video scan of the line to determine where the intrusion occurs. Are they cost effective? What is a typical charge? (The house is setback 30' from the street, the street is 35' wide.)

If/when the scan finds a section of damaged/collapsed pipe, what are the repair options?

Am I just better off Snaking this line until I move?

Thanks in Advance,

Rog Smith
