I paid a plumber $500 to inspect my clogged sewer line. He came out to the house, scoped and videoed the inside of the pipes. He found a clog and showed me a very unclear video. He would give me the video if he cleaned the clog (more money) or sell me the video if I wanted a copy. I was looking online and there were a huge amount of Sewer Scoping machines. I purchased this Kentfaith machine because I have other Kentfaith devices that have served me well. Within hours of receiving the borescope my wife and I scoped the sewer line. we took a video of the scoping and played it back on our computer. We found the obstruction. We then used our electric sewer snake and knocked out the clog. The cost for the equipment was less than one plumber visit. We have since helped a few neighbors with similar problems. We figured we have saved a couple of thousand dollars so far and the equipment is as good as new.
The only thing I would caution the user about is to treat this scope very tenderly. If you encounter anything obstruction or clog, stop and take care of it. Don't forget to wear a protective cover for the camera. Don't try to force the camera through the obstruction. This is a wonderful machine. I would recommend this to any and all DIY people and maybe a professional.
