I searched this (and many other) forums, and have cannot find the right answer. So here it goes (yes it's a common one)! I have a window well that sits 18" below the grade, at the base of the well, there is a 4" drainage pipe (black, perforated). In the basement, I have a sub pump, where there is another 4" pipe that comes in from the outside (I'm assuming that there is a weeping tile around that drains to this) The well builds up with water, and slowly leaks through where the sill sits on the foundation. I don't want to be cheap and just caulk the sill.. Can I just run a sewer snake through the drainage pipe to unclog the drain? (assuming there is a clog) or run the snake from into the drain from the sub pump. Are there any other suggestions?
