The "real" money in sewercam work is finding the major defect and digging to fix it. Which gets back to the thing Katen was talking about, which is you sort of need a dig crew, and a fix crew. Your right about that. When I was still in Chicago I use to work for a plumbing company and at that time we needed a drainlayers license to stick anything into a clean out. Do they still enforce that in the City? We always rented a camera when we needed one, and it not recommended to go past any obstruction, such as a small root blockage at 15'. You should pull the camera out, stick a rod in clean up the obstruction then continue on. So I don't know if those other companies you talk about carry a rodding machine with them, to fully inspect the line, or do they just stick the camera in for show? I guess what I'm try to say a camera is a major expense and could be economical for a sewer repair company, but just for strictly home inspections I think just subbing it out to a plumber is the way to go. I guess if you feel this is a good revenue source for your business, and in your area HI's are offering this service, then maybe it's a good idea, but in my area I have to worry about jurisdiction laws. Plus getting a homeowner to agree with a sewer line inspection, as part of a real estate deal. Also do you think your insurance might go up if your inspecting sewers? Frank
