Will De-Rooting Pipes Work Forever?
Is there a point when de-rooting the drain line will no longer work?
Yes. The reason you have to de-root drain lines is because the roots have entered the pipes through holes in the joints. Each time you cut off the roots on the inside of the pipe, the root in the joint remains. Every year that root gets bigger and bigger and as it does, it puts pressure on the inside of the joint. Just the way roots growing inside a rock on the mountain side eventually break the rock, the roots in the joints eventually break the pipe and the dirt from the outside begins the flow into the pipe. It's an important step to have your drain line camera inspected. Once you see the condition of the inside of the pipe and the amount of roots in your drain or sewer line, you can begin to plan for that day when you will have to replace it.
