Some of the oldest lines in North County run under Escondido, some of them original to their houses, and an original line from that era has been underground for the better part of a century. Clay sections, the piping used back then, joints every few feet, decades of roots finding those joints, it all adds up to a simple point. When something goes wrong down there, guessing gets expensive, and the sensible first step is to see the pipe.
That's the inspection. A small camera travels the line from the cleanout, the capped pipe outside that opens into your sewer line, toward the street, sending live video as far as it can get, and most of what's wrong shows up on screen. It might be roots at the joints, grease, food and sludge built up along the wall, scale, the mineral buildup that narrows a pipe, a belly, which is a low spot in the line that holds water, or a cracked or shifted section. Plenty of times it's a line that's aged but still working, needing a good clearing and nothing more. You can watch it live, and no repair conversation starts until you've seen what's down there.
The moments that call for it are the expensive ones, a big repair quote, a house purchase with a 100 year old line, or backups that keep returning no matter what gets cleared. A short look on video puts real evidence in your hands, and every decision after it is yours.
