This last winter, I had some flooding into the house from the outside drains from the gutter down pipes into the perimeter drain which backed up to a drain near a door. So I know that the drains from the roof connect into a common pipe that connect to a drain near the door. Okay, today I placed a water hose into this drain near the door and ran it for about 10 minutes before the water started to rise in the pipe. I do not know if the drains weep through holes in the pipe into the ground, or if they connect to a drain near the ditch at the front of the house. No water was seen at the ditch during this test. I also placed a second hose at another downspout from the gutters and it filled up quite fast, but did slowly drain down and is gone now. Again, no indication of where it went. Before I call some guy in with a camera to inspect the pipes, are there any suggestions from you guys? The pipe inspection guy will be well over $100.00, and of course if there is a plug, the cost goes up. Any thoughts?
