You can call the sewer scoping contractor, also called a pipe inspection service, shows up with a very long coiled metal hose that has a tiny video camera at the end. The camera view is classically visible on a video screen close to the main utensils, and many services record the entire scoping on videotape for the home buyers. My friend you can take help from scoping contractor or if you want training then you can search from the site which is very helpful for the purpose of sewer scoping. Believe me my friend this site is very helpful. http://www.visaliacaplumbers.com/
