A recent storm dumped a bunch of water into our window well, which then leaked into the basement. I was investigating the window well to determine how the water managed to pool, and I found a number of problems. From my research, it's my understanding there is a pvc pipe which is usually filled with landscaping rocks which allows drainage down to the weeping tile. I dug around in the bottom of the window well and found the pipe, but it was capped with an orange cap.
Does anybody recognize what this cap is meant to do? Should it have been removed before gravel was dumped into the window well? I screwed it off and the pvc pipe below is clean and empty. The cap is fully watertight when screwed on.
