A 4 inch pvc elbow with a cap on it in the corner of my basement had a crack in it. I started to excavate and then realized that there wasn't a pipe connected to the other side of the elbow. I then broke off the top to see what was inside (hoping it was treasure). Instead, I found a 2 inch wet corrugated pipe.
Any idea what this thing is?
Thanks for looking.
Adding: I have the PVC elbow off now. The corrugated pipe has slits down the side. I don't know if its purpose is to let something in or out though.
Also, outside, my gutters drain in to 4" pvc that is routed to the storm sewers.
Edit: Adding second picture with the PVC elbow removed. You can see the 2 inch corrugated pipe with slots now. The pipe seems to bend about 2 inches below the surface and travel level with the floor.
Edit: I excavated further. The third picture shows how it looks now. You can now see the flashing over the footer.
