What is drain tile ? A Drain tile system also called a French drain or weeping tile is a perforated pipe in a trench along side the footing inside or outside your house, “preferably outside” that carries the ground water away from the fountain. If you’ve ever had a backup or a flood, sewage and debris can cause issues and horrible smells, having your drain tile cleaned or flushed will fix that. It will also clear up the years of debris and sediment that have piled up. This is a possible cost effective solution to digging up your drain tile for a repair.
