Televised ducts under slab floor. Ducts are metal with rusting and water throughout. Measured the height of the drain til in sum pit and the height of the ducts and they are about the same height. The draintil should be lowered to reduce the water table under the house. After the water issue is resolved the ducts should be retelevised to see if they can just be spray lined or if they need to be spin cast mortared as well.
