I have a set of concrete steps which go from ground level down to the basement; below ground. I have a drain in the lowest point in the base of the steps. I bought the house, but the owner failed to mention that the drain had been clogged for years. Everytime it rains, there is a possibility of a flooded basement. I have tried a plunger, and I tried using a wire hanger like a snake. The wire hangar goes down about a third of a meter and stops. No matter how I twist or push, it stops in the same spot. I cannot see anything obvious obstructing flow. Any thoughts or wisdom would greatly be appreciated. DK0965
