How Do I Know if My Drain Tiles Are Working Properly?
Since your floor's footing tiles are not visible and typically cannot be adequately seen by a sewer camera, the only sign that they are working properly is if seepage through the floor, or around the floor/wall joint is detected. If such seepage occurs, and your sump pump is working, then your drain tile system is not.
